Real-time Hand Motion/Gesture Detection for HCI - Demo 1

[sawsenification]

slt,

plaize can you send me the code of this video : Real-time Hand Motion/Gesture Detection for HCI - Demo 1 to my mail yahoo: saloua.matmati@yahoo.fr

plaize help me

thank you

slt

Looks useful. What kind of background can you parse the hand from, because I noticed that finger tips aren't easily recognized when they lay over palm of hand? Also, how CPU-intensive is this for normal conditions?

Hi!, great work!!...

i'm in an openCv project too, can u helpme in the detection of the fingers?? i don't know how to find the points... :S

Thanks!

[feedmepaper]

Excellent work. Any chance of releasing an API soon so that some nice soul can port it over to AS3 for the lowly flash developers? The OpenCV face detection API has been ported over to AS3 by the guys over at the SPARC Project and it has fueled so much new development that I am sure that an awesome hand detection API like yours can really do wonders.

Thanks for sharing the video in any case and best of luck with whatever you are working on now.

The input video was only the hand or was there also a noisy background?

[nizkowsky2]

can u gave us the algorithm or codes to do a similar project

[15Larsy]

It doesn't seem to catch the thumb very well.

[geniox99]

Ccan you help with the coding?

[ElanHR]

I feel like the erroneous finger detections near the palm could be gotten rid of with the erode function in open cv. Very impressive none the the less. :)

@ElanHR

Oh hey! This is for professor Hager! Missed the first intro the first time, yay Hopkins! :)

[dane450]

Its master hand without his glove :O

@dane450 :)

[leemaomao1986]

Impressive!! which algorithm are you using? How can I do a similar project?

[smmy0705]

@leemaomao1986 Thanks. I devised my own algorithm to detect finger tips which is straight-forward and intuitive but works good as you see in the video.

[geniox99]

@smmy0705 can you help me with the code....im new to it.hope u can send me with the code 

[vastheaven]

what is your email address please?

[smmy0705]

@vastheaven It's in the video above -- m y j at j h u dot e d u

Hey guys, just wondering if you have an executable or the source to check the algorithm in action. Excellent report, I like how you finish it :)

Best regards,

Daniel

[smmy0705]

@dannyxyz22 The source codes or executable have not been released yet but it will be soon, hopefully. Yes, I still do remember the last part of my report... :)

[dannyxyz22]

Awesome results. Congratulations! I'm checking your report.

Best regards,

Daniel

[smmy0705]

@dannyxyz22 Glad you liked it! :)

[naosalem]

hi , i'm newbi in opencv and i'v started a code to detect the finger tip . untill now i can detect the contours of the hand and i dont know how to proceed can u give some help ; and how to englobe the hand into a rectangle

thanks

[smmy0705]

i just saw your comments. Sorry for the late response. If you still need some help, please email me. (you can see my email address in the intro part of the clip)

[b1ueocean]

Very Impressive - I've just recently downloaded OpenCV and blown the dust off of my C/C++ books - I have a biz idea that requires a decent level of gesture recognition. Can you recommend any publications (books, journals, sites) that assisted you in your work?

I've never heard of Bi-direction hysteresis, is there a good book or paper covering the fundamentals?

Many thanks in advance - keep up the good work.

[smmy0705]

Thanks :)

There are many many many papers, articles, and techniques available on the Internet. Probably you can get it easily if you want with several minutes' googling (email me if you want more specific references).

From my experience, however, the quality or the actual performance of algorithms were sometimes questionable. If your project really needs a pretty decent one, you definitely want to implement and compare them.

[manguztap]

How did you get the peaks of the fingers???

[smmy0705]

Bi-direction hysteresis to calculate peak points of a hand.

[manguztap]

Hey Muchas gracias, I'll implement it in my algorithm, I've not heard about it, but I'm gonna google it; I was using a trigonometric method to get the peaks, it is so unstable though. Regards from Mexico!!!

[smmy0705]

My pleasure :)

By the way, in the course of designing my algorithm, I've also implemented and tested the trigonometric method that you mention. The basic idea of the algorithm seems to be pretty good "theoretically," but it didn't work out well in my tests; it showed pretty high false positive ratio.

Anyway, please mail to me for more details; I 'm willing to share my experience with you.

[jacky5297]

may i know how did u get ur hand orientation ? Thanks :)

[smmy0705]

You can see a yellow box encompassing a hand. It is obtained from a binary hand mask that is the most tricky part of my algorithm.

Then I use the mask to calculate the orientation information which is pretty straightforward and easy.

Hope this might be a little bit helpful for you.

[jacky5297]

Would u mind revealing the algorithm of hand orientation ? or mayb a brief idea will do, thanks. :)

[smmy0705]

A brief idea is: the hand orientation is determined by the direction of the major axis of a hand, which can be obtained from a hand mask (binary image) - sorry for the late reply.

[multitouchy]

amazing stuff :)

[smmy0705]

Thanks :)

[marthastuart81]

This is awesome!! Can i share the algorithm??

[smmy0705]

Sure~ would be my pleasure. :)
