The first algorithm, of which subjects investigated are dynamic video frequency grey images shooted by our lab and grey images of CMU single face database, combines coarse segmentation of difference image with multi-template matching to detect faces.

• 算法一是以本实验室拍摄的动态视频流灰度图像及CMU单人脸数据库中的灰度图像作为研究对象，将多模板匹配与差影法粗分割相结合来检测人脸。
