SYSTEMS AND METHODS FOR STEREO DEPTH ESTIMATION USING GLOBAL MINIMIZATION AND DEPTH INTERPOLATION

摘要

Aspects relate to a method of generating a high resolution image containing depth information of an object. In one aspect the method includes downsampling a first reference image and a second reference image from a first resolution to a second resolution wherein the first resolution is higher than the second resolution and wherein the first reference image and the second reference image comprising a stereo image pair. The method further includes generating a depth map at the second resolution based on global minimization techniques using the downsampled stereo image pair. The method also includes upsampling the depth map from the second resolution to the first resolution and using a guided filter to align contours of the upsampled depth map to contours of the first reference image.
