[0041] The present invention will be further described in detail below in conjunction with specific embodiments.
[0042] figure 1A specific implementation flow of the video-based face tracking and recognition technology of the present invention is given. In step (2), a face detection operation is performed on the decoded video frame image. The present invention adopts the features of Block-Local Binary Pattern (BLBP) statistics samples (face images and non-face images) with region weights, and introduces them into the AdaBoost face detection framework. LBP is an operator that describes the contrast relationship in the local area of an image. Its calculation formula is as follows:
