Abstract

A system and method for stereo matching of at least two images, e.g., a stereoscopic image pair, employing a global optimization function, e.g., a belief propagation function, that utilizes dynamic programming as a preprocessing step are provided. The system and method of the present disclosure provide for acquiring a first image and a second image from a scene (402), estimating the disparity of at least one point in the first image with at least one corresponding point in the second image (404, 406), and minimizing the estimated disparity using a belief propagation function (410), e.g., a global optimization function, wherein the belief propagation function is initialized with a result of a deterministic matching function (408), e.g., dynamic programming, applied to the first and second image to speed up the belief propagation function. The system and method further generates a disparity map from the estimated disparity and converts the disparity map into a depth map.

Description

technical field

[0001] The present disclosure relates generally to computer graphics processing and display systems, and more particularly to systems and methods for stereo matching of at least two images employing a global optimization function that utilizes Dynamic programming is used as a preprocessing step. Background technique

[0002] Stereoscopic imaging is the process of visually combining at least two images of a scene taken from slightly different viewpoints to create the illusion of three-dimensional depth. This technique relies on the fact that human eyes are separated by a certain distance and therefore do not see the exact same scene. Tricks the viewer's eyes into a perception of depth by presenting each eye with an image from a different perspective. Typically, when two different perspectives are provided, the component images are referred to as the "left" image and the "right" image, also referred to as the base image and the supplementary image, respective...
