Fast face detecting method

The present invention relates to a rapid human face detection method which uses a human face detection device. The device comprises a digital signal processor which is provided with a first-in first-out memory, a synchronous dynamic random memory, an erasable memory, a complex programmable logic device, a video decoder, an image pick-up device, positioning algorithm software and data, as well as a computer-television signal display. The rapid human face detection method is to initialize a system, acquire an analog video signal including a human face image, convert the analog video signal into a digital signal as an input image, perform normalization processing to the image, perform image integral calculation, human face characteristic structure preprocessing analysis and CS-ADAboost classifier judgment so as to perform accurate post-processing and save detection results, finish whole-frame processing, and output detection results. The present invention can overcome the influence of illumination and pose in a certain degree to detection, and realizes human face detection function rapidly and accurately.
