Abstract: There usually exist some problems in color image such as noise，blur and background，which directly affect the face detection results.This paper puts forward a new method which combines image enhancement and skin segment with AdaBoost algorithm for face detection.The enhancement operation of smoothing and sharpening is used to input image to eliminate noise and enhance the edge information of the image.And the skin area from background using the skin segment method is effectively departed.The AdaBoost algorithm is utilized to locate accurately the face position in candidate region.The experiments illustrate that this method has a better improvement to the problem of leak detection and error detection.
