A study of fast, robust stereo-matching algorithms
Stereo matching is an actively researched topic in computer vision. The goal is to recover quantitative depth information from a set of input images, based on the visual disparity between corresponding points. This thesis investigates several fast and robust techniques for the task. First, multiple …
