Image processing method and apparatus, electronic device, and readable storage medium

An image processing apparatus, comprising:

• a processor and a memory;
• wherein the memory stores computer executable instructions, the processor executes computer executable instructions stored in the memory, enabling the processor to:
• acquire a to-be-processed image, wherein the to-be-processed image comprises a target object;
• acquire, by adopting a feature model, normal feature information and target feature information of the target object, wherein the target feature information comprises:
• depth feature information and/or tangent feature information;
• perform, based on the normal feature information and the target feature information, a lighting rendering on the target object in the to-be-processed image to obtain a lighting-rendered-image;
• output the lighting-rendered-image.

A non-transitory computer readable storage medium, wherein computer executable instructions are stored in the computer readable storage medium, and when a processor executes the computer executable instructions, the following steps are implemented:

• acquiring a to-be-processed image, wherein the to-be-processed image comprises a target object;
• acquiring, by adopting a feature model, normal feature information and target feature information of the target object, wherein the target feature information comprises:
• depth feature information and/or tangent feature information;
• performing, based on the normal feature information and the target feature information, a lighting rendering on the target object in the to-be-processed image to obtain a lighting-rendered-image;
• outputting the lighting-rendered-image.
