Parallel research of shape context face recognition algorithm based on CUDA

The shape recognition serial algorithm of Shape Context and parallel processing platform of CUDA are studied in this paper. According to multi-processor pipepine characteristics of CUDA platform, the Shape Context algorithm is made to be adapted to CUDA platform. Through paralleling algorithm, the higher implementation of precision and more than 130-fold speedup are obtained. The purpose of dealing with the real-time processing of the huge amounts of data on face recognition is satisfied.
