Hand guesture recognition using openCV

When i was searching in google for openCV’s hand guesture recognition, i found one library which is called HandVu by accident. On its demoes showed on webpage, the functionalities seems indeen powerful, interacting with virtual 3D objects, controlling virtual menu and the most important thing is that it is background independant.

However, i think, openCV’s default functions which are included in its library maybe probably have this abilities. As a result, today i found a openCV function called

CvConvexityDefect

-Structure describing a single contour convexity detect

and there isĀ  a illustration picture on the side of the instruction like below:

So, on the positive side, that means once the hand contour is extracted, it is possible to detect what guesture the hand has. And that, would be a big step of object recognition.

    Hi!
    First of all congrates for doing such wonderful an motivating works. May be you are so havituated to all those, bu for me you are a rock-star. Presently I am involved in a project of “Controlling Robot Motion by Hand Gesture”, and your suggestions are really proving helpful to me. Keep doing good jobs.

    Thanks,
    Deb, India

    Hi!
    In hurry I did some spelling mistakes in the reply…Whatever leave it. I want to know; have you done any project for hand gesture matching in OpenCV?

    hi will you tell briefly how to detect the gesture of hands to perform action from it

    Hi Andol,
    I am a beginner in openCV, what should i learn in openCV to make interactive programs for my projects.

    thank you
