Matching-Area-Based Seam Carving for Video Retargeting

This paper presents a video retargeting method considering both spatial and temporal coherence for resizing videos. Our algorithm is based on a novel matching-area-based temporal energy adjustment that allows per-frame seam carving to remove the optimal pixels to achieve spatially and temporally continuous resized videos. The temporal energy adjustment allows the seam to track the object it previously carved, and avoid carving the seam on different objects in two consecutive frames to achieve both spatial and temporal coherence. Our method outperforms other state-of-the-art retargeting systems, as demonstrated in the results and widely supported by the conducted user study.
