Abstract:
1. A face image processing method, which is applied to an electronic device, comprising the steps of: automatically performing a face detection to a digital image to obtain a face image in the digital image; marking a frame on the face image after the face image is obtained; performing a skin color detection to the face image corresponding to the frame to exclude non-skin features on the face image, and forming a skin mask on the face image within an area range belonging to a skin color, wherein a multi-seeds algorithm is adopted when the skin color detection is performed to the face image, and the multi-seeds algorithm comprises the steps of: forming a predetermined quantity of uniformly arranged seeds within the frame; determining whether or not a pixel color at a corresponding position within the frame is the skin color according to the position of each seed, in order to perform a skin color filtering; computing a center color for the pixel colors belonging to the skin color after the skin color filtering takes place; and sorting the pixel colors and the center colors corresponding to all the seeds, and deleting the seeds having colors different from the center color over a predetermined chromatic aberration, and the remaining seeds become the skin mask; and performing a filtering process to the area range corresponding to the skin mask on the face image to filter high-frequency, mid-frequency and low-frequency noises in the area range of the skin mask.
