基于BP网络的人脸朝向检测

he field of biometric identification, face recognition with high practical value and broad application prospects.In order to make intelligent robot vision system to recognize the human face direction, This paper uses BP neural network and the Matlab neural network toolbox research face recognition technology, research person face's direction in image. Experiments based on BP network designed by Matlab toolbox, realize the face recognition.?Using the knowledge of BP neural network.Discussed input and objective vector design, and network parameters and training parameter setting, etc. Experimental results show that the BP network can according to the input image information, with certain accuracy recognition of image face toward.
