Hand gesture detection and recognition using openCV
Related Posts: Hand guesture recognition using openCV
Clicking the pictures and the detailed previews will display which show the hand contours extracting from video capture. These pictures illustrate the results of color based segmentation for hand gesture detection ( not recognition yet ). it is a real time programme, however, in this demonstration, the programme still depends on environments’ light , because of the color based segmentation method. If, combinned with motion detection and background substraction, it supposes to be robuster.








Hi andol. Great work! How did you finally manage to detect the contour of your hand with the noise and stuff? From an older post it reads “But the noise is easy to take off”… how did you do that?
Well, i used two steps to get the noises away which include using blur to smooth big contours and to melt numerous small contours, secondly, according to the hand characters, select largest contour as target.
Hi. Will you be posting your code for this as you did for the circle detect? In the circle detect, there are two includes for math.h. Not being a C++ coder, I wonder what the differences in syntax between ” and < are for the math.h include files. Cheers.
Oh, the twice includes of math.h in circle detection codes was a mistake. You can delete one of them and debug it again, that would be fine, no different. About the code, yeah, i ll update it soon.
can u share the source code for this?
The codes have been published.
The codes are here: codes
hi li,in the page http://www.andol.info/hci/1097.htm
I dont find the gesture recognition code , I have download hsv.cpp in the “sharing code” page which is not the one showing in this page.
Oops, sorry for that some posts were lost by mistake couple days ago while debugging. So that post number is not previous one with source code. Big apologies.
Me podrias ayudar, estoy tratando de hacer algo parecido, mas segun yo voy en la segmentacion
plz Andol
i do a project that detect the hands in a difference states so w need ur advice how do this ??/
sure i would like to.
Thank you,
very interesting article
you welcome
hi would you please show this code ,i need this kind of code for my implementation
fantasfic work ..really helpfull.
hi i need this codes ,the codes u specified is not avilable woud u helo me
sorry the previous codes are indeed invalid. New codes refer here: http://download.andol.info/hsv.cpp
Hi Andol! I’m new to opencv…lately i’ve been trying to do hand detection (detect hand and place a circle around it)…can you please help me? do i need to use haar classifier?
Thank You
haar classifier is used to detect specified and predefined gestures, it is stable and effective once the training is finished. If you can get sufficient examples both positive and negative it would be very recommended to do so.
I m doing the exact project in my engineering final year project but i have not used HAAR cascades but i have used skin segmentation to filter hand skin…. wud be glad if u can share ur email address so that i can clarify my doubts….. need some guidance in hand gesture recognition.
contact can be found in http://www.andol.info/about
Sir i have mailed u on ur hotmail account with some screenies and our exact problem…. we r anxiously waiting for ur reply…
thank you…
