Skin image processing method and device, equipment and storage medium

The invention provides a skin image processing method and device, equipment and a storage medium, and relates to the technical field of artificial intelligence. The method comprises the steps of obtaining a to-be-processed skin image; performing bilateral filtering iteration processing on the skin image to be processed to obtain at least one filtered image; determining a diffuse reflection image corresponding to the to-be-processed skin image according to the to-be-processed skin image and the at least one filtered image; and inputting the diffuse reflection image into a pre-trained deep learning model to obtain at least one skin substrate layer pigment image corresponding to the to-be-processed skin image, the skin substrate layer pigment image being used for displaying pigment features of the skin substrate layer. According to the technical scheme, the skin substrate layer pigment image corresponding to the to-be-processed skin image can be obtained based on the deep learning model, and the pigment features
