Hecate is a video analysis library released by Yahoo that detects scene changes in videos and picks representative frames to automatically create thumbnails, animated GIFs, and short summary videos. It filters out blurry or dark frames and scores segments to pick those that best represent the whole video. It is written in C++ on top of OpenCV and can be used both as a command-line tool and as a library.
Automagically generate thumbnails, animated GIFs, and summaries from videos
