Abstract:
1. A method for generating a virtual image for a virtual view of a 3D scene based on a texture image and a depth image, wherein the depth image includes an associated dense depth image and associated sparse dense features, comprising steps of: applying a first depth enhancement to the dense depth image and the sparse depth features to obtain a first enhanced depth image; determining a plurality of candidate depths for each pixel of the first enhanced depth image; determining; for each candidate depth, a cost that estimates a synthesis quality of the virtual image; selecting a candidate depth with a least cost to produce an enhanced depth for the pixel in the first enhanced depth image; and applying view synthesis to the first depth images and the corresponding texture image to generate the virtual image, wherein the least cost is based on stereo cost, a color intensity consistency between two views, and a color difference cost wherein the steps are performed in a processor.
