Other AbstractThe invention relates to a key-frame extraction method based on dictionary selection. The method includes the following steps: adopting a VIBE background modeling method to judge whether each frame of an original video is a foreground frame or a background frame and extracting a foreground video section with continuous foreground frames; using a video semantic segmentation method to carry out second segmentation on the foreground video section so as to obtain video sections; extracting characteristics of each video section and aggregating the characteristics of the video sections so that a dictionary is formed; and using a dictionary selection method to extract key frames. The key-frame extraction method based on the dictionary selection uses key frames to substitute a complete video so that monitoring efficiency is improved, transmission time and storage space of monitoring videos are saved, resource waste is reduced and device utilization rate is improved.
