A gesture recognition system is developed based on the lasted skeleton extracting algorithm and Euclidean distance transform. The system consists of generic video acquisition module and ARM. Firstly
gestures region are segmented by dynamic forescene detection algorithm combined with skin color detection model of YCb Cr;secondly
the Delta-medial axis skeleton extraction algorithm and Euclidean distance transform are applied to obtain Eudidean skeleton so as to extract geometric parameters
and key points on the skeleton. Then a gesture recognition model is built by these geometric parameters. Test results show that the overall recognition rate reaches 94 %
processing time of each frame image is less than 25 ms
which shows that the system is real-time and effective.
