Aiming at the problem of lowactivity recognition rate from 3D human skeleton sequence based on a single descriptor and a single feature coding method,we propose a method based on multi-descriptor feature coding. Firstly,moving pose descriptor and angle descriptor are extracted respectively from 3D human skeleton sequence. Then,vector quantization coding,sparse coding and locality constrained linear coding are employed respectively to get six kinds of feature based on two kinds of descriptor. Finally,linear ...
