Occlusion Boundaries from Motion: Low-Level Detection and Mid-Level Reasoning

摘要

The boundaries of objects in an image are often considered a nuisance to be “handled” due to the occlusion they exhibit. Since most, if not all, computer vision techniques aggregate information spatially within a scene, information spanning these boundaries, and therefore from different physical surfaces, is invariably and erroneously considered together. In addition, these boundaries convey important perceptual information about 3D scene structure and shape. Consequently, their identification can benefit many different computer vision pursuits, from low-level processing techniques to high-level reasoning tasks.
