 Okay, so we have many students who were not able to do so, but no issues. We will be guiding them. We would be supporting all of you to get the access of those resources and so that you can start working on the quiz and can ensure your certificate for the bootcamp. Okay, so now I will start with our today's part. Okay, so again, welcome to the code over 2021 mission AI bootcamp number one. And today is the day three where we are going to learn about the object detection. But before that, let's see what do we have. So, as you already know, that code over 2021 international, we have title sponsors as more one is a foundation. This competition is hosted by stamp area and art park AI in robotics technology part, which is an initiative of ISC Bangalore. The competition is accredited by stand.org. We have my still schools and well your subjects as an AI education partner. We have amazing price sponsors, hero cycles, lilligo sun founder and cipher toys. We have also a good community partners who are spreading spreading the words of artificial intelligence to the students around the world. We have Guru Shala, Niti IO, Augusta Foundation, Jodo Mission AI, and I start really. Now, I hope you might have already downloaded the certain downloaded the pictoblocks and installed it in your favorite device. But again, if you have not downloaded the pictoblocks, no need to worry, you can scan this QR code on your screen. Also, we are going to share you the links on the chat from there. You can download the pictoblocks and all your devices so that you can learn and make projects in your ease. So I would be helping you regarding the registrations in the pictoblocks like signing into the pictoblocks, but don't worry. Yeah, we would be sharing that. Don't worry. But still, as I mentioned, the first thing is like if you have not downloaded the pictoblocks, don't wait. Okay. Please download the pictoblocks and the link is so now you can see we are going to share you the link to download the pictoblocks. If you want to download it in your laptop PC, here is the link. If you want to download it in your Android phone, this is the link which you can use which I'm just now pasting on it. If you're using the iOS application that is iPad or iPhones. So again, you can use the link mentioned on the chat to download the pictoblocks. Now, a small recap that what we did last day. So if you are new, don't worry the things we are starting. So we are going to give you a small recap. So we talked about. So the questions of the students, right? So we would be taking your query students towards the end of the session. Don't worry. I would be demonstrating you each and every part, each and every issue you are facing. Okay. So now the small recap. So last session, we saw the introduction to artificial intelligence where we were able to see how what exactly AI is that to which machines we are calling that these are enabled with artificial intelligence. Then we came up onto the applications of AI that were exactly the AI is used like we saw about expert system gaming systems and making recognitions. Okay. Now, the next part was how the face detection work to hope you remember that the face detection works with the you can see the image as well with the face landmarks. It is detected. It first detects the face landmarks, then it makes a pattern and after that it compares it with the knowledge what computer have. Now, the next part was making a face expression detector activity. So I hope you all have already made this activity. Okay. And if not, if you are finding a problem, don't worry. Don't worry about it. We would be sharing the replay video that would definitely we will be sharing your replay video link that is going to definitely help you to revise the lesson. So as I mentioned, don't worry if you have not attended the last sessions, we have a replay videos for you. So let me just paste the playlist for all of you. So I'm just stopping the chat for reserve now so that you can all get the links with you. So this is the link for the replay. Okay, okay, you might have also received this in your emails and today after the session also you would be given the link in your emails, but still if you want to have it you can have it from here let me just change a little bit to this. So this is a playlist for the replay video. Okay, so I think now it's on your chat box. So if you have missed any of the sessions no need to worry you can revise or you can check out the video on to the YouTube. Don't forget to subscribe the YouTube channel. Now, coming to the next part, the object detection. So as you know, today we are going to learn about the object detection, that how exactly it works, what are its benefits, what are its different applications and how can we make an activity into the pictoblogs. So are we all ready to learn the object detection. So can we have a response on the chat with object detection that will make me understand that are we are we are all excited to learn this topic. You can just write OD, okay, you can just write OD, that means object detection on the chat that will give me an understanding that we all are excited to learn today's topic. Can I have your responses on the chat students, I'm waiting for your responses of OD that will give me an understanding that we are all ready to learn today's topic. So I'll just check with Neera, Neera, I'm audible clearly. Okay, okay, that's great. So now I think, okay, I'll just, okay, I'm sorry, I disabled the chat again, I was waiting for your chance. So now, okay, now let's move to I can see now the OD on the chat. Okay, thanks students. So now we'll move further with today's topic. Okay, so the first things come up that what exactly the object detection is okay and wherever where are the different fields, we are locating it right where are the different fields we are using it I should say. So, object recognition is a general term to describe a collection of related computer vision tasks okay that involves identifying the project in different photograph. So you might have been thinking what exactly this is written and that how exactly I'm going to relate to it. Okay, so you can see the image here. Okay, you can see a video is running on just beside of it. So what exactly this means is that object detection is a normal technique of a computer vision. Okay, which is able to find and locate the different objects, like you can see on the image that the machine is able to detect the bus, the person, the people, I should say the car, the motor. I hope I'm audible, I think there was some technical glitch that's why I just came out of just went out of the room need of audible. Yeah, you are audible. Okay, that's great. So now I am available I can see where he is where the service so I'm here now. Okay, can you see me and hear me properly students. Okay, yes. Okay, thanks. Okay, thanks for mentioning. Okay, I got your message here. Okay, they want you mentioned audible, your video and audio is clear mentioned by Tanmay, and all the students so thanks for responding on the chat and confirming it. So we were talking about the object detection rate. So as I mentioned that object detection is basically you can say it as like it is going to, it's a set of activities it's not a complete one thing, but it's a set of activity where first it is analyzing the different images. Okay, after that it is coming up with the detection of the objects. And the third part you can say it, it is locating the different objects with a bounding box and coming up with a tag. Okay, so this complete things called as a object detection. So as on the side also it is mentioned that it locates the presence of object with a bounding box. So you can see it was in the image also. So it is able to detect the people person bus car everyone and also coming up with a bounding box. So this is what we called as an object detection. Things come up that how exactly this object detection work. Yeah, Jesse, I will take your question. So the things come up that how exactly this object detection work. So object detection works in the three steps. Okay, this is very like major three steps, although there are very small, small steps in between. But if I talk about a major three steps, so the first is it generates the small segments in the input. So you can see a picture of a person holding I should say, a baseball pack. There is a ball, right. So now this is the first part what happens in backend, or I should say in background is it is able to okay so Mr. Neera I would kindly request you to paste the attendance form as well. Okay, I'll just paste this. Okay, so this is the attendance form students, you can fill it later or you can fill it. But the first important thing is you should also be presented the session okay so you can fill it later you can keep the link with you. So now talking about that how exactly this object detection is working. So as I mentioned the first part is it is going to generate the small segment so you can see the picture is now being divided into the segments. And after that you can see the second points come up that they are feature extracted from the segmented rectangular area to predict there is an object or not. So in the second picture you can see there are very small rectangles and now the new rectangles have came up. Okay, so they are trying to detect that this is an object or not. Okay, so now you can see here you can see there is a small box near to a ball there is a box on to the bat. Okay, you can see there are two boxes on the person. Right, so just in this way there comes a many boxes so far just demonstration we have showed you a small boxes but what happens here is there are many big boxes coming up here. Okay, which is going to basically just give me a second which is going to come up and predict whether there is an object or not. Okay, once the objects are finalized. Okay, the third steps comes up that the overlapping boxes so you can see there are so many overlapping boxes right. So if I talk about the one object that is a person so you can see there are three different boxes right so what happens here is the final output is that it is able to detect the multiple objects after overlapping the small boxes. So now the machine told us okay after finalizing all the things I found the three objects one is a person one is a bat and one is a ball. So yeah, you can ask your doubt. So I hope this part is very clear I'll just give you a small recap on this. So the first part what happens here is the image is first divided into small segments. Okay, so this input image has been divided into very small segments. After that the features are extracted on a new rectangular box come up overlapping overlapping each other where they are trying to detect or predict that there is an object. Once this is finalized you get a final output that yeah confirm this is one object. This is one object as a bat and this is one object as a ball. So I hope this part is pretty clear to all of you. Now moving to the next part is of course the thing which you always wait for that is making an object detected. So I think we all are very much ready for this. Okay, so now I will just stop my share and we'll move to I'm sorry we'll move to directly to the pictoblocks. Okay, so I'm sorry. Okay, I hope my pictoblocks screen is visible to everyone right. So no worries if you have missed the attendance form for day one no issues Karnika. Okay, there is no problem. How to get a new project so I will tell you you can get a new project by going to the file and clicking on to the new in this way you will be able to get a new project. Okay, I think Jerry and some of the students were asking this question so you can get a new project by clicking on the file and then clicking on the new button. Okay, so now coming to back to the point which we were discussing about the object detection. Okay, so now how we can make an object detector into our own pictoblocks. So the first part which is very, very important is signing into pictoblocks. So right now I'm signed in so I'll sign out myself. Okay, and now I would be signing in back I would be showing how you can sign in. So I would request all the students to see this very, very carefully because this is a very major step for making this project. Okay, without signing in, you won't be able to use this extension. So make sure you sign into the pictoblock as soon as you click on sign in. Okay, if you are like I should say new user, you have to click on register. After that, you have to click on student, you have to mention about your age, and then you have to give your email ID. After this, you have to create your own username, create your own password, confirm that password and click on create my account. This process is going to send you an email on to your email ID which you have mentioned. And there you have to click on I agree to agree. You have to click on I agree. And that will basically make verify you as that you are the owner of the email ID. Okay, and then you have to come back to this screen just fill a small information and you will be signed in. Okay. Also, I would like to tell you that we are going to use one of the best extensions of pictoblocks today. So that will require some credits. So I will tell you what exactly the credit is. Let me just get into my account. So what exactly the credit is. Okay, so to use the premium services of the pictoblocks, you should have the pictoblocks user credit so that you can make wonderful projects on artificial intelligence, and you will be happy to know that we have decided to give all the students 5000 credits, very free of cost. The code for the getting I should say the key I should say the redemption key would be sent on to your emails. Okay, by the end of the day for so that you can redeem that key and get 5000 credits. How you are going to redeem that case, you once you are signed in, you have to click it here. You have to click on the credit, and then you have to click on you have to, I should say, give the key which I would be sending out to you, and you have to click on go. Okay, once you will click on go, your pictoblocks user credits will be increased by 5000. As I mentioned, we have decided only these for the students who are attending the boot camp. Okay, so this is very important that you check your emails for the code. You will try to send you buy that today. Also, if you are signing in for the first time, you would be getting 1000 credits for free. So some of you are saying that you already have an account. So it's amazing. In that case, you only need to go to this part click on credit and get your keys redeem which we will be sharing it to you. Now, coming to the topic of object detector that how exactly we can make it. So you have 1000 credits. So it's great but as I mentioned you would be requiring more to make wonderful projects to be part of the COVID whatever competition. That's why we would be giving you more credits for free of cost. Okay, so now, now coming back to the, the activity rate that is the object detected. So how can we do that. So the most, the most important thing is that we will need to add the extension. So what do, so what do you need to do here is you will be in need to click on add extension button. Okay, so just give me a second. Yeah, so you will be in need to click on add extension button. My screen is little blurred. Okay, just give me a second. Let me find a solution to it. So just give me a couple of seconds. I'll try to find a solution to it so that you will be able to see everything clearly. Just give me couple of seconds students. I think now my screen would be clear rate. So can I have your responses students that now my screen is clear. I hope now my screen is pretty clear that now you can see the blocks and everything right. So now to start with the activity it's really very important as I mentioned that you have to sign into the picture blocks and after signing into the picture blocks. So now what you have to do is you have to click on our extension. As soon as you click on our extension. So today, we are going to use. So I can see some more. Yes. Okay. So may I confirm this with Neera. Neera is my screen clear. Can you hear me? Yeah, I can hear you. Your screen is visible. It's clear. Clear. Okay, that's great. So now the thing which we need to do here is the students we need to add an extension. So some of you mentioned that you were not able to add an extension. So what do you need to do is you will need to click on add extension button here. Okay. And as soon as you will click it here you will be able to find the different extension. So the extension what we used last day was face detection. And today I can see you guys are mentioning about different extension or I should say the extension which you are going to use. Okay, how can we download the pictoblocks in our Android phone? So now you can download it in your Android phone directly by searching it onto the Play Store or also we would be sharing you the link. Okay, so don't worry about it. We would share you the link so that you can access you can directly download it. So today we are going to add an extension that is AI extension. Right. And here I can see we're done. Yeah, I would request not to spam the text. It's good. We don't that you know it and we can see it clearly but don't spam the chat. Okay. So yeah, we have added an extension. This of course require an internet right. So now coming to the part that how do how we should start. So today what I'm going to do is I'm going to start with the first block that is when green flag is clicked. So I hope this is pretty clear to you means it is visible although I just try to make it more visible. Okay, so the first block is when green flag is click. Now a very important thing is that we need to give the data. Right. So how can we do that is we would be able to doing that by using a block into an extension that is turn on the camera. So this is the block. Okay, let me just minimize a little bit. Yeah. So this is a block students where you will be able to see the video on your picture blocks as soon as I click it here, I would be visible on to like I would be visible here as well. Right. So I think I'm visible on to your picture blocks as well. Right. So now the this is going to help me to detect the objects from the camera, but if in case I want to detect the objects from different images in that scenario, what you are going to do is you're going to add a backdrop. Okay, and after adding a backdrop, you will be recognizing the things. So the next very important block which you need to use is that is the recognize the image feature from the stage. Okay. And this is the block students very important because this is only going to recognize the different things. The first was the first block was going was opening the camera. The second one is detecting the images detecting or I should say recognizing analyzing the images from the stage. So this is very, very important. Now, the things come up that there could be many objects on the screen right now if I talk about so you can see many objects right. So, okay, just let me just go through with the chart. Okay. Okay, so now coming back to the this activity as I mentioned the next part is like we would be detecting many objects, but of course, we would also know the counting of the objects right that how many objects are exactly present right now. So to count those objects. So someone asked me this question on the first day that what exactly the variable is the student variable are like a box where you can store the numbers or you can store the alphabetical units that we called as a string. Okay, so you can store a string or you can store a number inside a variable, and you can make your own variable using an option of make a variable. And why we are making a variable so that we can keep track that how many objects are currently present on the screen. So I'm going to click on make a variable and I will give the names as objects. And I would be keeping the data type as numbered because of course I want to store the number here and I will just click it here. And as soon as you click, okay, you would be able to see the objects coming up on the stage. So this is by this checkbox. So if I'm going to uncheck this, it will go away. If I'm going to check this book again, this would come up. The important thing here is students is that again, like, like on every detection, like every time I'm starting a program, I want my machine to start the counting from zero, right. Okay, can you zoom on to the box. Dear, if I zoom it, it will just go a little bit. It will just get cut. Okay, no issues. I think you would be able to see now. So what we have to write on key while signing is so you don't need to write anything. That's an optional. You can just keep it blank and get into the next step. Okay, so now students as I mentioned, I have already clicked into the all its price. Okay, so I was telling you about this was the first step and we created my variable to get that keep the track of number of objects in my image or I should say on the live camera. But of course, as I mentioned, every time it the this program is a starting, it is very important that it is very important that the counting start from zero. So for this, I have a block that is set my variable to zero. And here I would in need you can name it at objects. Yeah, I have named it at object. So now here you have to select the name of the variable, what you have created, right. You have to select it as zero. And why am I doing this as I mentioned that every time I start a program. My machine should start the counting with zero. It should not be like this that in this image, there were three objects that counted one, two and three. And then in the next it count the counting started from five, I should say 456 to start every time with zero, we are putting up set the objects to zero. Now, again, there are some very important concept concepts or no, we would be sharing you the link of attendance or you can even see the attendance link on top of your chat box. Now coming to the part that, of course, the number of times the object is going to be there, we need the number of times the sprites are coming. Okay, so one of the major thing I wanted to tell you here was that today we won't be using the Toby as a sprite. Okay, we would be changing our sprite. So what am I going to do here is I'm going to choose a new sprite. Okay, and that would be a square box. Because to locate the object, of course, I won't be able to do it with the Toby. So if I want to locate the objects, I want some sprite like a square box that can help me to locate the objects. Okay, so this is why I'm choosing this square box as a sprite. But now you would be thinking that I have written everything in Toby, I'm not able to see it on the square box. Okay, so no issues. What you can do is you can just just give me a couple of seconds. So now if you have you are seeing this square box as an empty. So what do you need to do is you need to just drag this script and go to square box. And if you will see square box moving rate, we will see the square box is shaking, the sprite is getting shaped in that way you will be able to copy the sprite. So this was very important thing I wanted to cover that how you can, I should say copy the sprite script from one sprite to another. So now I would be deleting the Toby from here. So now I only have one sprite. That is the square box, which I would be using to locate the different objects. Okay, so I can see students are also sharing the attendance form. So are now I would request you not to spam the chat, we would be sharing you the link of that and inform. Okay, so I'm keeping the chat off for some time so that everyone in the chat can get the link for this form. Okay. So now, as I mentioned, I have added a square box as an sprite and I copied the complete script from Toby to square box. Now, how many times I want this sprite to locate the objects. Okay, so this should be equal to the number of objects. Okay, so like right now if I say there will be five objects. So I want my square box to move five times. So this is one object, this is one object, this is one object, this is one object, right. So my sprite should move five times or I should say it should come up five times onto the screen and to repeat the things as I have mentioned. That you need a block which is which says repeat. So I'll just bring this block which says repeat. So now you can see there is a number of course we are not confirmed with the number right because there can be five objects there can be 10 objects or there can be one object. So what we can do is we can use option that is recognized object count. Okay, and this is going to automatically update that how many times do I want my sprite to come up on the screen. Now the next point which is very important as I mentioned, so we need to track the number of objects. So to track, of course we would be in requirement to increase the number as well. So first time it's zero. So after once one object is counted, we need to add one number, right. So we'll go to variables and we will change the variable by one. So the name of my variable here is objects. So every time a new object is detected, I want it to get added to zero. Okay, this will start increasing the number so that at the end of the program I would be able to get the final number of objects. Now, here comes a very important concept that we have only one square box, right, but we can have a multiple objects on the screen. So how can I get my box or I should say how can I get my sprite multiplied by many times. Alright, how can I get multiple sprites with only one sprite selected. So we can get multiple sprites with only one sprite selected by creating the clones of that sprite. And you can do it very easily by choosing the control and what do we need to do is we have a block which says create the clone. Here you will see there are two blocks and these are complementary blocks. That means if you are going to use this block, you have to use this block. Because if you are asking the sprite to clone, then in that case you have you also need to mention that what should be done when you are creating a clone. So this is why we are creating a clone here. Okay, and now we are also using that when I start as clone. So what do we want to do when we start as clone. The first very important thing would be that I want my sprite to set its size. Okay, so how can I do that. So in the looks, we have a block which is going to help me set the size to so I'm taking down this. Okay, and this is written as set the size to but what I want how exactly what should be the size of the box, which is coming up. It should be something I should say big enough to surround the object which has which it has located. So what do we need to do here is we are going to go to the artificial intelligence, and we are going to go to image features. And here you are going to get an block which is going to say recognized object count. And instead of x, you can choose the height. Okay, so right now I'm setting the object. I'm or I should say I'm setting. Let me just minimize this here. So I'm setting basically the size of the sprite. Okay, what I'm doing, I'm setting the size of the sprite that it should be equal to the height, or it can be also the width. So we have seen that it's we find a good answers with the height. So this is what we are doing that if it is coming on my face. So right now you can see it is not covering all of my face. So I want the when it is finding the object, it should be also getting a size of the object. Okay. Now, the second important thing, as I mentioned that in object detection, it's very necessary that it locates the object that if it is detecting me, it should come here. If it is detecting robot, it's my machine should say my sprite should go somewhere in the backside. I'm not able to hold this. Yeah. Okay, now it should come here. It is if it is detecting some other so it should locate that objects rate to locate that objects, we have to go to the motions and we have an option to set the X and Y coordinates. Okay, so I will take two of the blocks that is set X to and set Y to and here we're going to see choose the same block. Okay, that we use was let me just bring it down. That is recognized recognized object X position recognized object Y position. So I will just change it to Y position. I will again explain you this part that when I started as long that I mentioned key when I would my sprite would be making its clone. I want the clone size should be the height of the objects detected. It should be located at the X position of the object detected. It should also be located at the Y position of the object located right after this, of course, a very important thing is to get the name. So what do I will do is I'll just go to look. So I'm sorry, I'll go to look and bring up this block which says say, okay, and this is going to help me to say the name of the object. And again, I will go to artificial intelligence, and I have a block here, which is going to help me to say the name, which you can see it here. Okay. Now, you would be thinking that we are tracking the number but why we are tracking the number. So we are tracking the number because so means I should say, we would be able to locate this box onto different objects, we are numbering the objects right. So here on this part when I started as clone, you can see all the numbers are 111111. Okay, so what it is going to do is it is only going to come up over the, I should say, the object number one, okay, and it is only going to set its height as object number one. But of course, we don't want that. What we want here is it should come up onto all the objects, like it should come onto the object number one, then it should come up onto the object number two, then it should come up on the object number three, and it should be done automatically. So I'm going to bring this object variable, which contains the different, I should say, it contains the different numbers inside it, right. So I'm just going to put object inside this. I'm also going to put object inside this part, so that it gets automatically update and the things come up onto all the objects which are detected. Okay, so I'll just minimize this so that you can see the complete script in one go. Just give me a second. Okay, a little bit here. Okay, I think now it would be clearly visible. Okay, and now let's see whether it works or not. I will show you one important concept here. Okay. So now what do I need to do is let's keep this right somewhere at the corner. Okay, I want all of you to focus there that I'm keeping this is right at the corner. Okay, and now if I click it on the green flag. So now you can see the two sprites came up the first was a person so this is what I wanted right so I wanted it should come up with my height. This is not exactly the my height which is visible on the camera, the box came up with that height. Again, on the glasses part, so it came up with that height, or you can choose the width also. So it's totally upon you, but a very important thing. I detected two objects, and here there are two clothes coming up. But as I mentioned that this was the original sprite, and it was still there at the corner. So what do I want to do is I will be in need to hide it. So I can go to looks and what I want is I want my original sprite to be hidden. So I'm just directly going to put a high block here on to the top. This is going to hide the original sprite. And it will only bring the clones. So what I'm going to do here is I'm going to bring a show here, and I'm going to put it show when I start as well. So I'm hiding the original sprite and only showcasing the clones of it right now if I'm going to click on green flag. Now you can see the original sprite is hidden. And now let's see. So now you can see it has came up with person and the glasses. So you can see if I use the width, although it's covering due to like I should say, due to with what it is doing is it is covering my whole face. So that is why I what I thought of keeping it to height, then also you can see every time I'm starting it. So the objects are getting changed or I should say the number is getting updated by two. So now you can see how easily it is getting getting the things detected. So I can try one more thing here. I have a bottle. So let's see whether it is able to detect this bottle or not. Okay, it was not able to detect the water bottle. Let me just try it again. So now you can see it detected the three objects right first one was the person second one was the glass and the third one is the bottle. So now this way you would be able to detect the different objects. Now, coming to a very important part that students might be facing. Okay, so let me just see this. Okay, that you mentioned that how do we use the camera into the picture blocks of the smartphone. Right. So what I'm going to do here is I'm going to stop my share and reshare the things for you.
