Pop quiz: Clapping hand

asked 2013-04-05 11:20:44 -0500

I'm working on a project where I have to detect hands clapping - ideally where the hands meet; the approaches I've tried thus far are: - getting the centre of gravity from the last frames mask (using the absolute difference from an accumulated background image)

  • centre of gravity on a mask based on skin thresholding

  • optical flow; I group all the features based on distance and work out the average distance between the 2 largest groups.

(2 example images shown below).

The user can clap anywhere (ie not in a controlled environment/situation).

Any suggestions, hints, tips, solutions would be greatly appreciated,

Josh

You could try how the kalman tracker performs, based on your skin segmented hand regions.
