Abstract
Video retargeting from a full-resolution video to a lower-resolution display will inevitably cause information loss. Content-aware video retargeting techniques have been studied to avoid critical visual information loss while resizing a video. In this paper, we propose a mosaic-guided video retargeting scheme to ensure good spatio-temporal coherence of the downscaled video. Besides, a rate-distortion optimization framework is proposed to maximize the information retained in the downscaled video.
