Abstract: The face recognition system of parallel genetic neural network was realized in the paper.BP network is one of the most effective algorithms in face recognition field.This paper pointed out some places that not fit the multi core computer system in the algorithm of BP network,and then put forward a new parallel algorithm of genetic neural network,which optimizes the BP neural network algorithm from the topology and weight value.The new algorithm improves the recognition rate and speed than the original algorithm more significantly.The effectiveness of genetic neural network parallel algorithm was proved in the ORL experimental data.
