Star skeleton for human behavior recognition

Against to the traditional single-view two-dimensional body shape can not describe the diversity and ambiguity of human action, this paper present a 2D action recognition method based on human 3D star skeleton. It use multi-view two-dimensional body shape to describe and identify human action. The offline training process set up the 2D star skeleton codebook and 3D skeleton sequence. The online recognition process put up the vector quantization, get the matched 3D skeleton and then identify the human action. The experimental results show that this method has high recognition rate.
