Document Type and Number:
WIPO Patent Application WO/2022/012085
Kind Code:
A1
Abstract:
Provided in embodiments of the present application are a face image processing method and apparatus, a storage medium, and an electronic device. The method comprising: by acquiring original face image data, generating a face grid image according to the original face image data; determining an offset vector of each pixel point on the face grid image according to a normal texture map; offsetting each pixel coordinate on the face grid image according to the offset vector of each pixel point on the face grid image to obtain deformed face image data; and rendering the deformed face image data to obtain a deformed face image. Performing an offset vector calculation on each pixel point during the process of acquiring deformed data and not involving complex square root extraction and other operations improves the accuracy and fluency of processing a face image and improves user experience.
