A block-based face detection algorithm suitable for the video coding system is proposed. In the proposed method, the facial blocks are basically detected by using the DC values of chroma components. And the DCT coefficients obtained in video encoding are used for the accurate detection of the facial blocks. Simulation results show that the detection ratio and the computational gain of the proposed algorithm are averagely 88% and 50%, respectively.
