Image processing method and apparatus, computer-readable medium, and electronic device

An image processing apparatus, comprising:

• at least one memory storing a program;
• and
• at least one processor configured, when executing the program in the at least one memory, to:
• respectively project, according to a plurality of view angle parameters corresponding to a plurality of view angles, a face model of a target object onto a plurality of face images of the target object acquired from the plurality of view angles, to determine correspondences between regions on the face model and regions on the face image, the face model having a given topological structure;
• build a two-dimensional (2D) texture image template according to the face model;
• respectively extract, based on the correspondences and target regions in the face model that need to generate a texture image, partial texture images corresponding to the target regions from the plurality of face images, wherein each partial texture image represents texture of a connected pixel region on a face depicted by the plurality of face images;
• and
• fuse, according to the 2D texture image template, the partial texture images that correspond to the target regions and that are respectively extracted from the plurality of face images, to generate the texture image, the texture image being a 2D image.

A non-transitory computer-readable medium, storing a computer program, the computer program, when executed by at least one processor, causing the at least one processor to perform a plurality of operations comprising:

• respectively projecting, according to a plurality of view angle parameters corresponding to a plurality of view angles, a face model of a target object onto a plurality of face images of the target object acquired from the plurality of view angles, to determine correspondences between regions on the face model and regions on the face image, the face model having a given topological structure;
• building a two-dimensional (2D) texture image template according to the face model;
• respectively extracting, based on the correspondences and target regions in the face model that need to generate a texture image, partial texture images corresponding to the target regions from the plurality of face images, wherein each partial texture image represents texture of a connected pixel region on a face depicted by the plurality of face images;
• and
• fusing, according to the 2D texture image template, the partial texture images that correspond to the target regions and that are respectively extracted from the plurality of face images, to generate the texture image, the texture image being a 2D image.
