Video data is growing exponentially daily due to the popularity of video-sharing platforms and the proliferation of video capture devices. The video summarization task has been proposed to remove redundancy while maintaining as many critical parts of the video as possible so that users can browse and process videos more effectively, which has received increasing attention from researchers. The existing research addresses the challenges faced by video summarization methods from various perspectives, such as temporal dependency, data scarcity, user preference, and high precision. This paper reviews representative and state-of-the-art methods, analyzes recent research advances, datasets, and performance evaluations, and discusses future directions. We hope this survey can help future research explore the potential directions of video summarization methods.
