A survey of recent work on video summarization: approaches and techniques

Abstract

The volume of video data generated has seen an exponential growth over the years and video summarization has emerged as a process that can facilitate efficient storage, quick browsing, indexing, fast retrieval and quick sharing of the content. In view of the vast literature available on different aspects of video summarization approaches and techniques, a need has arisen to summarize and organize various recent research findings, future research focus and trends, challenges, performance measures and evaluation and datasets for testing and validations. This paper investigates into the existing video summarization frameworks and presents a comprehensive view of the existing approaches and techniques. It highlights the recent advances in the techniques and discusses the paradigm shift that has occurred over the last two decades in the area, leading to considerable improvement. Attempts are made to consolidate the most significant findings right from the basic summarization structure to the classification of summarization techniques and noteworthy contributions in the area. Additionally, the existing datasets categorized domain-wise for the purpose of video summarization and evaluation are enumerated. The present study would be helpful in: assimilating important research findings and data for ready reference, identifying groundwork and exploring potential directions for further research.
