Abstract

Determining disparity includes obtaining a first image of a scene and a second image of a scene, determining correspondences between one or more pixels of the first image and one or more pixels of the second image, performing local denoising on the correspondences based on at least on a strength and direction of gradient values for the one or more pixels of the first image and the one or more pixels of the second image, and generating a disparity map based on the determined correspondences and local denoising.
