Abstract
A large number of cameras record video around the clock, producing huge volumes. Processing these huge chunks of videos demands plenty of resources like time, man power, and hardware storage etc. Video summarization plays an important role in this context. It helps in efficient storage, quick browsing, and retrieval of large collection of video data without losing important aspects. In this paper, we categorize video summariztion methods on the basis of methodology used, provide detailed description of leading methods in each category, and discuss their advantages and disadvantages. Moreover, we discuss the situation in which each method is most suitable to use. The advantage of this research is that one can quickly learn different video summarization techniques, and select the method that is the most suitable according to one’s requirements.
