Abstract

It has become more and more demanding for users to obtain quick comprehension of video content, while big multimedia data is growing exponentially. Video summarization, also known as video abstracting, extracts the essential information of a video to produce a compact and informative version. In this talk, he will present recent studies of his team in this field. While most of the existing methods rely on global visual features to characterize each video frame, they for the first time formulate the video summarization task as a keypoint selection problem from a local feature point of view. Based on this new perspective, they develop a new keypoint coverage approach and a novel Bag-of-Importance (BoI) model for static video summarization. He will demonstrate their state-of-the-art results, as well as discuss potential directions of this topic.
