Abstract
This application provides an image processing method performed by an electronic device. The method includes: acquiring a diffuse reflection map and a shadow map of a three-dimensional (3D) model of an object, wherein the 3D model is constructed from a plurality of photos of the object within a predefined lighting environment; acquiring a shadow texel in a shadow region of the diffuse reflection map according to a corresponding shadow region in the shadow map; querying an average color lookup table according to spatial coordinate information of the shadow texel for an average brightness difference corresponding to the shadow texel; and determining restoration color information according to the average brightness difference, and restoring color information of the shadow texel according to the restoration color information. In this way, shadow in the diffuse reflection map of the 3D model can be effectively removed or at least attenuated.
