The document presents a video summarization technique called Correlation for Summarization and Subtraction for Rare Event (CSSR). The technique extracts frames from input video, calculates the correlation between frames to identify redundant frames, and discards similar frames to create a summarized video. It also identifies objects or actions in areas of interest by subtracting summarized frames from the stored background image of that area. The technique was tested on videos and able to successfully create short summarized videos while also detecting objects in specified areas of interest. The authors conclude the technique provides an optimized solution for automatic video summarization and security monitoring with reduced manual effort.
