Abstract
The application relates to a portrait image skin retouching method, apparatus, an electronic device, and a storage medium. The method comprises the following steps: identifying a skin area and a portrait structure area contained in the skin area from a portrait image to be processed; determining a skin analysis area, which is a remaining area of the skin area except the portrait structure area; fitting a pixel value distribution in the skin analysis area by utilizing a Gaussian mixture model, to determine one or more model parameters of the fitted Gaussian mixture model; determining a retouching intensity parameter based on variances the model parameters; and performing skin retouching on the portrait image to be processed based on the retouching intensity parameter. With the method, the proper skin retouching effect can be achieved for portrait images with different image qualities.
