Abstract: A fast approach of face detection for video surveillance was proposed. A symmetrical frame difference was used to acquire tne motion area. A simple and fast segmentation algorithm, 1.e. mid?point-guiaed growing, was developed to search the skin-like pixels and segment the face-like regions. The distribution information of shape and feature in each face-like region was examined and those re?gions satisfying with the knowledge of a human face were located and marked. The experimental re?sults show that the accuracy and processing speed are very promising. The approach can be used to de?tect multiple faces with different poses and sizes. It is a practical method for developing visual surveil?lance system and can be used as a start point for face tracking research.
