Shot detection in HEVC/H.265 video

The huge number and volume of video and video usage have caused most of them saved and transferred as compressed video. Nowadays, indexing, searching and retrieving video directly in compressed domain has been taken great attention. The first step in video indexing and retrieval is segmenting a video into chronological sets and manageable pieces or shots. In recent years, a new video coding standard say H.265 has been introduced and it is needed to develop the methods and algorithms for analyzing, indexing and retrieving H.265 compressed video. In this paper, a novel method has been proposed for shot detection in H.265 compressed video without full decompression. In the proposed method, macro block coding information which is in headers of compressed H.265 bit-stream by a threshold is used for shot detection of compressed video. The results indicate that the proposed method detect video shots in H.265 video by 80% accuracy and 84/3% recall.
