IMAGE SEQUENCE COMPRESSION FEATURING INDEPENDENTLY CODED REGIONS |
摘要 |
In a MPEG or other video coding system, regions of each frame may be independently coded for later, independent extraction or processing directly from a compressed bit stream. An encoder/transcoder (115) receives raw video (103), standard compressed video (105) or compressed video already having independently coded regions ("ICRs") (107) that are to be edited in some manner. The encoder/transcoder permits user creation of regions, and provides automatic tracking features to identify and select those objects or regions through multiple frames (notwithstanding object movement). The encoder/transcoder re-uses as much compressed input data as is available in generating an output, and so, may be used for real-time encoding and editing processes. To this effect, the encoder/transcoder re-uses original bit stream data as well as original or new motion vector data in compiling an output, or any mix of them as appropriate. |
