Abstract: An approach of key frame extraction from hazard installation monitoring video is presented. Due to the characteristics of hazard installation monitoring video, DC images is compared to reduce the redundant information and get effective video. Key frame extraction algorithm based on shot for MPEG compressed video is used to get the final result. The experimental result illustrates that the approach can extract key frames from hazard installation monitoring video effectively.
Key words: hazard installation monitoring, key frame extraction, DC image, MPEG video stream
