Tools for Compressed-Domain Video Indexing and Editing

Indexing and editing digital video directly in the compressed domain offer many advantages in terms of storage efficiency and processing speed. We have designed automatic tools in the compressed domain for extracting key visual features such as scene cut, dissolve, camera operations (zoom, pan), and moving object detection and tracking. In addition, we have developed algorithms to solve the decoder buffer control problems and allow users to "cut, copy and paste" arbitrary compressed video segments directly in the compressed domain. The compressed-domain approach does not require full decoding. Thus fast software implementations can be achieved. Our compressed video editing techniques will enhance the reusability of existing compressed videos.
