Extraction of features for indexing MPEG-compressed video
Vikrant Kobla, David Doermann · 2002
Development of various multimedia applications is dependent on the availability of fast and efficient storage, browsing, indexing, and retrieval techniques. Given that video is stored efficiently in a compressed format, the costly overhead of decompression can be avoided by analyzing the compressed representation directly. We describe techniques that can be used to extract viable features for indexing shots of video directly from the compressed domain. We develop a type independent representation of frames present in an MPEG video and show how it can be used directly for indexing.
