Refinement of Depth Maps by Fusion of Multiple Estimates
First Claim
1. A computer-implemented method, comprising:
- generating a plurality of initial depth maps for a first image of a stereo pair, wherein the plurality of initial depth maps for the first image are generated using at least two separate and distinct techniques for depth estimation;
generating a plurality of initial depth maps for a second image of the stereo pair, wherein the plurality of initial depth maps for the second image are generated using at least two separate and distinct techniques for depth estimation;
generating a fused depth map for the first image based on the plurality of initial depth maps for the first image and the plurality of initial depth maps for the second image; and
generating a fused depth map for the second image based on the plurality of initial depth maps for the second image and the plurality of initial depth maps for the first image.

Abstract
A method, system, and computer-readable storage medium are disclosed for generating fused depth maps. A plurality of initial depth maps are generated for a first image of a stereo pair, using at least two separate and distinct techniques for depth estimation. A plurality of initial depth maps are generated for a second image of the stereo pair, using at least two separate and distinct techniques for depth estimation. A fused depth map is generated for the first image based on the plurality of initial depth maps for the first image and the plurality of initial depth maps for the second image. A fused depth map is generated for the second image based on the plurality of initial depth maps for the second image and the plurality of initial depth maps for the first image.
