Refinement of Depth Maps by Fusion of Multiple Estimates

A system, comprising:

• at least one processor;
• and
• a memory coupled to the at least one processor, wherein the memory stores program instructions, wherein the program instructions are executable by the at least one processor to:
• generate 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;
• generate 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;
• generate 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
• generate 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.

A computer-readable storage medium storing program instructions computer-executable to perform:

• 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.
