The invention relates to a method and a system for adjusting the skin color of a human skin area in an image. The method comprises the following steps: obtaining a to-be-processed image, preprocessing the to-be-processed image, and obtaining a gray-scale map of the to-be-processed image based on a pre-trained skin color image detection model according to the to-be-processed image after preprocessing. Since the intensity of the grey-scale map corresponds to the probability of the skin color transformation area, the skin color transformation area in the grey-scale map is determined according to the grey-scale intensity of the grey-scale map, and compared with an algorithm for detecting the skin color through deep learning and determining the skin color transformation area according to the original to-be-processed image in the prior art, the method is more accurate, higher in speed and lower in time delay; in addition, the skin color does not need to be changed through a color lookup table, and extra space consumption cannot be caused. According to the invention, color transformation is carried out on the skin color transformation region based on the preset rule, soft light mixing is carried out on the skin color transformation region after the color transformation and the skin color transformation region before the color transformation, and output is carried out to obtain the processed image.
Description
technical field [0001] The present application relates to the technical field of image processing, and in particular to a method and system for adjusting the skin color of a human skin area in an image. Background technique [0002] Skin color transformation is one of the new requirements in the field of modern image and video processing, which requires users to freely change their skin color. There are two issues to be considered when performing skin color transformation processing on an image, one is how to identify the skin color area, and the other is how to transform the skin color. In the prior art, when identifying the skin color area, most of them find a better range containing the skin color in different color spaces, and use the color falling within this range as the skin color to determine the skin color transformation area, but this The accuracy of the method to determine the skin color transformation area is low. When the image or video contains a color similar...
