Abstract
A skin color detection method comprises: determining chrominance signal values in a luminance chrominance YUV domain of a pixel value corresponding to each pixel point in a target image under skin color detection; searching for a skin color probability corresponding to the chrominance signal values in a stored skin color index matrix based on the chrominance signal values in the YUV domain of the pixel value corresponding to the pixel point, wherein the skin color index matrix is generated through processing skin color images under various illumination conditions, and the skin color probability is a probability that the pixel point is a skin color point; and performing skin color detection based on the skin color probability corresponding to the chrominance signal values of each pixel point in the target image. A skin color detection apparatus and a storage medium are further provided.
