The exponential growth of technology has resulted in a profusion of advanced imaging devices and eases internet accessibility, leading to an increase in the creation and use of multimedia content. Analyzing representative or meaningful information from such massive data is a time-consuming task that impacts the efficiency of various video processing applications, including video searching, retrieval, indexing, sharing, and many more. In literature, numerous video summarization techniques which extract key-frames or key-shots from the original video to generate a concise yet informative summary have been proposed to address these issues. This paper presents a discussion of the state-of-the-art video summarization techniques along with limitations and challenges. The paper examines summarization techniques in a holistic manner based upon the distinct attributes of evolving video data types on the basis of parameters such as the number of views, dimensions, modality, and content. Such a categorization framework enables us to critically analyze the recent progress, future directions, limitations, datasets, application domains etc., in a better comprehensible manner.
