Abstract:

     This article designed a face detecting and cutting system based on skincolor space and integral projection. Firstly, this article set skin color model from the input image. In this step, a part of the skin area sample is selected,upper limit and lower limit of chroma threshold by experimental statistics is determined, and then the skin area is cutout by “double threshold” methods. Secondly, morphological process binarization image is carried out. Finally, integral horizontal projection and vertical projection are made, the skin area is determined by locating eyes, and the image is cut in accordance with the requirements. In condition that input images are limited to “contain single bareheaded face, face clear, expression natural and solemn”, our detection accuracy is above 96%. This system has strong practicability, and is easy to operate.
