This post is about to introduce an efficient method of detecting and recognising hand gestures using the convexity detection of openCV, as illustrated in the picture on the left. In contrast to the previous work of detecting hand contours, this method steps further to recognise gestures of hand pretty accurately, meanwhile this shows possibilities of extend such work into using simple hand gestures to manipulate computer applications.
For more details, here is a relevant tutorial video made by original author who explains who this works.
Here gives the source code of this video demonstration.
