Abstract :
Occlusion/disocclusion is one of the fundamental problems for semantic video object (SVO) extraction because the tracking degradation from occlusion/disocclusion creates difficulty for the pixel-wise accuracy requirement and adds to the amount of user interaction required in off-line video editing applications. We present an approach based on the application of a new extensive operator in a lattice of partitions, that exploits information from various views of the scene to address the disocclusion problem by using a regional Bayesian formulation. Our multiview operator builds on the application of the maximum a posteriori (MAP) principle, by integrating a single view region classification stage and a multiview stage that solves for disoccluded regions labeled as uncertain. Results on several real sequences show that this approach improves the quality of the extracted SVOs and reduces the total amount of user interaction
