1. A method for three-dimensional face generation, comprising:
- calculating an inverse depth map based on a depth map and an inverted first matrix, wherein the inverted first matrix is generated from two images in which pixels are aligned vertically and differ horizontally;
normalizing the inverse depth map to correct for distortions in the depth map caused by image rectification; and
generating a three-dimensional face model based on the inverse depth map and one of the two images.

Abstract
A method for three-dimensional face generation is described. An inverse depth map is calculated based on a depth map and an inverted first matrix. The inverted first matrix is generated from two images in which pixels are aligned vertically and differ horizontally. The inverse depth map is normalized to correct for distortions in the depth map caused by image rectification. A three-dimensional face model is generated based on the inverse depth map and one of the two images.
