Outline of Final Research Achievements

Inferring important region in a video is a technique that can be used for various applications, and a number of approaches have been proposed so far. Most of these approaches model the visual system of animals and inferred regions may not be very consistent with expected important regions, especially when watching a video. In this project, we focus on a videographer’s intention and propose an approach for important region inference when watching a video. We also develop fully-automatic video privacy protection and video summarization as potential applications of the proposed important region inference approach and experimentally demonstrate their performances.
