Method and apparatus for adjusting skin colors of portrait, electronic device and storage medium

An apparatus for adjusting skin colors of a portrait, comprising:

• an image acquisition module, configured to acquire an initial portrait image to be adjusted;
• a skin color category probability determination module, configured to determine a plurality of skin color category probabilities that the initial portrait image respectively belongs to a plurality of skin color categories predetermined;
• a mapped pixel value determination module, configured to calculate a mapped pixel value of each pixel in the initial portrait image according to the plurality of skin color category probabilities and a plurality of skin color mapping tables respectively corresponding to the plurality of skin color categories, and wherein the mapped pixel value determination module is further configured to:
• acquire the plurality of skin color mapping tables corresponding to at least one of the plurality of skin color categories,
• determine, for each pixel in the initial portrait image, a plurality of skin color mapped values by mapping an original pixel value of the pixel to the plurality of skin color mapping tables:
• and
• determine the mapped pixel value of each pixel by using the plurality of skin color categories probabilities as weights to perform a weighted summation on the plurality of skin color mapped values;
• and
• a skin color beautified image determination module, configured to determine a skin color beautified image based on the mapped pixel value of each pixel.
