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 …

High-quality dense stereo vision for whole body imaging and obesity assessment
… work of our lab, we developed a prototype active stereo vision system that demonstrated a potential to fulfill this goal. But the prototype required four computer projectors to cast artificial textures on the body which facilitate the stereo-matching on texture-deficient images (e.g., skin). This …
