Video browsing system based on compressed domain feature extraction
We present a video browsing system that dynamically extracts features and other content-description (meta-data) from compressed video. We devise a description scheme for a video browsing system that combines color and motion descriptors extracted in the compressed domain. The extraction is fast and enables our proposed dynamic feature extraction based video browsing system. We examine the tradeoff between fast feature extraction and accuracy of matching to arrive at a combination of color and motion descriptors that is easy to extract and provides accurate matching.
