ABSTRACT:
An image processing system using bitstream information for enhancing visual display quality. The processing system retains I frames and some P or B frames from a standard MPEG-2 bitstream, and stores the information across multiple Groups of Pictures (GOPs). The system uses prediction block information in conjunction with detected object edges and bitstream vector information to analyze object optical flow and to reconstruct high quality image frames. The system can also utilize supplemental bitstream information such as layer coding, instructional cues, and image key meta data to further improve the quality of the image frames and for special system functions. When an input image does not include MPEG-2 motion vector bitstream information, the system uses techniques such as optical flow, block matching, or Pel-recursion to estimate motion that tracks the image object motion.
