法要好-This article describes the DSP6711 hardware features　analysis of face detection, recognition of the principle and algorithm selection　the use of the LDA transform domain DCT-based feature extraction method, to achieve automatic recognition of human faces. In the Yale face database of experimental results show that the algorithm is the recognition rate than the direct use of PCA for feature extraction method is better
