Color Tracking Kalman Filter

[marskahn]

interesting~~~I like it~~~

[pr4wn5tar]

Getcho freak on!

[sira1rc]

like this..

I am a beginner learn openCV. Could u send to me this programing?? I will to try make program how to detect object..

[belloorso]

Hello i see the kalman filter and i need the matlab implementation. Help me , my mail is alfaromeo78@libero.it Thank you

[decasT]

lol, the first thing some people seems to do is to ask for the source code. How laughable is that.

[r3dux]

@decasT How is that laughable? I'm learning OpenCV and I'm doing so by reading books, experimenting with and dissecting other peoples code (including that from the book).

You learn through experimentation, and that's just what the people asking for the source code want to do. At best, they'll do something cool with it and share THEIR source code, at worst they do nothing with it.

[sficht]

source code?

[moutazaramin]

nice work

can you send to me the source code

moutaz_aramin@yahoo.com

[moutazaramin]

nice work

can you send to me the source code

moutaz_aramin@yahoo.com

[moutazaramin]

please i need the source code

[robomatics]

Very cool man, I'm trying to do the same in visual basic, but thanks to you, i think I now get how to do it. Thanks for the inspiration!

[msukar23]

hi it is amazing work

i am engineering student

i need to know how i can tracking accelerating object like this

can u send to me the matlab object

i will be very happy if u help me

if u interested : this is my email ssukar23@hotmail.com

[ysfkfnd]

Wont you share this great implementation with us. I'm willing to understand Kalman filter better but can't yet because of the bulk of theoretical background. I would be very happy understanding how you modelled your tracking system.

my email is antiderivada at gmail

thanks.

Hi this is excellent..

Am also working on object tracking using kalman filter ,previously i worked using mean of the object..

now am not getting the kalman filter , can u please send me your matlab code.

I have taken a video offline and read this into matlab using mmreader and segmented it . and in each frame i located the object using its color and found mean. Now i want to do  it using kalman filter ,please can u helpo me. thank you for your valuable time.. waiting for ur reply.......

[scifi4000]

Thanks for sharing great Kalman demo and MATLAB implementation. I'm trying to present the Kalman filter at the end of out digital signal processing course. Can you share code with me?

[sidouo]

can u tell me how we can do gabor filter with openCV plz

[sergio1020881]

excelent

[FairOnlineWorld]

this music is making me crazy in a bad way lol

[vuthienanvn1]

hello,

can you share the matlab code with me

[isabelceo]

may you please share the maltab code with me

[justinkwj]

hello can you please share the matlab code with me

[isabelceo]

I'm doing my degree project with kalman filter using matlab, will that you can give me advice

[hoangsonk49]

yes,of course. Kalman filter is better than Histogram, because if you use histogram to track, it 'll be difficulte for u to detect objects with many colors. And industry doesn't like it

[MrPholos]

nice but i dont understand for what the tracking??

[rfengr]

to demonstrate Kalman filter algorithm with a simple color tracking application. This could be used as the basis for tracking moving objects of different colors when it is correlated with a coordinate system. For example, colored balls, or tracking robots playing soccer. There are many applications for this in many domains.

[nikerun2004]

muy buen trabajo y aproposito cual es el nombre de la cancion

[isabelceo]

you can share the matlab code with me

[hoangsonk49]

I think he used Open CV. Actually, Matlab or open CV is not good for researching. You should use Visual C

[rfengr]

No, it was matlab.

[sira1rc]

@hoangsonk49 it's openCV right?? could i know the code?

[umeshnarayanan]

nice one , i think you have devloped this one with openCV using color filtering , can u explain it how the alogrithm working

[ehrenk1]

i am wondering how you modeled the control inputs for this system being non linear (asuming your movement is unpredictable) this would mean your using EKF? extended kalman fiter? Or is this a simple implementation being position + (vel state1-state0) + noise.

any help would be appreciated. Im not running matlab but processing.

[nowqin]

Can you share this kalman matlab code?

[JeromeDemers]

Very nice!!

You should try tracking a bouncing ball!

[sacevoy]

nice - should check out the applications of kalman filtering in high frequency finance ...

make some $ from filtering

[maple03maple03]

cool, nice job!

[strpwnownz4]

ok,

[strpwnownz4]

wat for progamme u use?

[rfengr]

matlab

[csikjarudi]

I thought the matlab does not calculate fast enough for this (almost) real time tracking, does it?

So you say I do not need to write some C code for this speed, right?

[rfengr]

this video was not real-time. It was recorded in frames, one picture at a time, and made into a video. This is why you see the picture jumping and skipping. However, I did optimize a very simple color tracking code for real time tracking, and yes it performs very well. In other words, it depends on how efficient your code is, and what you need the application for.

[rfengr]

Actually, if you notice that one of the printed parameters is Frames: out-of/600, so there are approximately 600frames/60sec, so about 10frames/sec for this color tracking using matlab. Realistic real time, like TV, requires around 50 to 60 frames. Computer Games/graphics require at least 30frames/sec.

[csikjarudi]

Thanks for your answer. Great job, anyway.

[eemahsa]

rfengr, could you share the code or if it is on the web give the address. thanks in advance

[Mifiglio47]

where did you get the Kalman filter algorithm?

[rfengr]

I got it from the farmer's market. It was a bit rusty and old, but after I buffed it a little bit it was shiny again :p.

well.. what do you mean where did I get it? you have to read articles, publications, and notes, and then you develop the code from the math.

[Mohannaddess]

I hope your aint using matlab builtin filter... anyways . nice work

[rfengr]

Actually, I did use Matlab, but it was not a built in filter. I developed the code.

[Mohannaddess]

Cool Man... Whats your background if i may ask?

[rfengr]

Electrical/Computer Engineering and Computer Science

[Mohannaddess]

I thought so dude, I am actually taking stochastic control course at the ECE /UofT although i am not ECE, i must admit, you are doing a good job here,

[rfengr]

Cool, your about three hours away from Queen's

[Mohannaddess]

walking!

[ashishrd]

Awesome! I like that blue thread which stretches between two objects.

[karanNdrums]

I like the line concept. It gives an actual rubber band feel. I think this concept can be used in areas like CAD.

[rfengr]

Note: the orange color has a Kalman-filter tracking algorithm that predicts the next center location coordinate of the orange color. The predicted Kalman location is the purple point, which closely follows the center location blue point.

The green color is another tracked color the represents a reference point. The distance between the two colors (or centers) is displayed as a blue line.
