The Scene Analysis and Keyframe Extraction for Content-Based Indexing on Compressed Image Sequence
압축된 영상 시퀀스에서 내용 기반 색인을 위한 장면 분석 및 키 프레임 추출
Abstract
In this paper, we proposed several scene analysis algorithms. These algorithms using image difference and histogram operate on the sequence of DC coefficient which is extracted from Motion JPEG or MPEG without full-frame decompression. Since DC sequence has the most information of full frame while it has reduced data. Experimental results show less than 1/64 of full frame analysing complexity and exactly analyze scene changes and extract key frames.
