Abstract: By decomposing the color face image into HSI space;generating a three channel face image template;and using HSI-PCNN algorithm of three channels extracts facial feature sequence，the feature sequence can be used for face recognition. An experimental comparison shows that this method can distinguish facial features well，while retaining the skin color information from the face. The HSTPCNN face recognition method，when compared to the original PCNN method performed as well as other face recognition methods. The proposed method for face detection process is simple and the identification accuracy is high. In order to achieve better outputs，after repeated experiments and parameter adjustments，this proposed method using for face recognition showed strong robustness.
