Combining video encoder and content analyzer to improve the encoding efficiency by content-aware algorithms is very challenging now. For the aiming application of low cost hardware real-time encoder with face detectionfor videophone, this paper proposes a face detection algorithm to detect each macroblock (MB) as one part of a face or not. This face detection algorithm has a unique estimation-and-verification process and can be combined with a H264 encoder by MB level pipeline architecture. 97.91% MBs in faces can be detected. VLSl architecture of proposed face detection algorithm is designed and an area of 4.3k gates is achieved. Power consumption is only 1.45mW at 100MHz. The detection speed achieves 1315fps in ClF sequences.
