Abstract

An electronic device and method for texture map generation are disclosed. A set of color images from a set of viewpoints and depth information of a subject's face are acquired. A 3D model is generated based on a color image and the depth information. A set of viewpoint-specific projections of the 3D model are generated along the set of viewpoints. The 3D model is refined based on minimization of difference between each viewpoint-specific projection and a corresponding color image. A set of texture maps corresponding to the set of viewpoints is generated, based on the refined 3D model, and set of color images. A dynamic programming workflow is executed to determine seams along which respective portions of the set of texture maps are to be stitched and the respective portions are stitched along the seams to generate a final texture map for the refined 3D model of the subject's face.
