With the development of society, there is increasingly exigent need for the fast and valid automatic identification technology in each aspect. Because the Biologic characteristics are the inner attributes of human beings, possessing strong stability and individual diversity, so they are ideal basis for identification. Comparing with other biologic characteristics such as fingerprint and iris, face recognition is more easily accepted by users because of many advantages of directness, friendliness and convenience, so currently it has been a top research in realms of pattern recognition and artificial intelligence. Face detection and recognition technology as an important researching content in Human-Machine alternation, has great theoretical meaning and application value.This paper does a deep research on face detection method based on skin color information and face recognition algorithm based on Embedded Hidden Markov Model, and introduces the construction of developed face detection and recognition system, the performance analysis and concrete application.The main contributions of this work are as follow: process face detection, location and facial feature extraction for frontal color face image; propose the face recognition approach using 2D Discrete Cosine Transform and based on Embedded Hidden Markov Model for detected face region. Experiment demonstrates that the face recognition approach based on 2D-DCT and E-HMM makes better use of 2D statistic characteristic of face image and has higher recognition effect and robustness; research faces sketch recognition, propose a new image-to-sketch algorithm; apply face detection and recognition system into practice. For the corpse face recognition, construct anonymous corpse source searching system. Such system provides powerful technical support and guarantee for detecting case of security, which has important researching and developing value.
