Video summarization has become increasingly important in today's world where vast amounts of video content are produced daily. The process involves creating a shorter and condensed version of a long video, which can still provide the main information and context of the original video. Video summarization can be achieved through different techniques like shot detection, scene segmentation, keyframe extraction, and video summarization algorithms. Therefore, the summarization technique depends on the purpose of the summarization. For instance, the purpose may be to extract a particular scene, highlight a crisis, or extract a critical insight. Moreover, summarization technology can be applied in numerous fields, including security, surveillance, news broadcasts, education, and entertainment. It can, for example, help to reduce hours of video to a few minutes, making it easy to search, browse and manage video data. Besides, it helps to minimize the storage and transmission of vast quantities of data, therefore saving time and resources. In conclusion, video summarization is crucial in various fields as it enhances the efficiency of video data handling and creates a more manageable format of video content.
