Abstract

Motion plays a fundamental role in coding and processing of video signals. Existing approaches of modeling video source are mostly based on explicitly estimating motion information from intensity values. Despite its conceptual simplicity, motion estimation (ME) is a long-standing open problem itself and accordingly the performance of a system operated on inaccurate motion information is unlikely to be optimal. In this paper, we present a novel approach of modeling video signals without explicit ME. Instead, motivated by a duality between edge contour of image and motion trajectory of video, we demonstrate that the spatio-temporal redundancy in video can be exploited by Least-Square(LS) based adaptive filtering techniques. We consider the application of such implicit motion models into the problem of error concealment or more generally known as video inpainting. Our experimental results have shown the excellent performance of the proposed LS-based error concealment techniques under a variety of information loss conditions.
