Abstract: Face recognition is a crossed subject of computer vision, pattern identification, biology character identification, and digital image processing. Skin color division is one of the most important steps of face recognition. Aiming at the current condition that the skin color division based on YCrCb color space can't distinguish the face accurately in the strong light, a modified division method of YCrCb color space is put forward to improve the adaptability and accuracy of YCrCb in strong light. The experiment verifies the conclusion that this new method can reduce the influence of light luminance on the human face segmentation operation, therefore it will be more accurate to find the face region and the error ratio is low.
