  • Patent number: 7068720
    Abstract: Methods for coding the current frame of a video data bit stream are provided. Methods include, for example, creating and maintaining a global codebook of historic values for the macroblocks of previous frames; searching entries in the global codebook to find the best estimation of the current frame and calculate a measure of the difference between values for the two macroblocks; comparing the effectiveness of the estimation macroblock provided by the global codebook entry to the estimation provided by a motion compensation scheme; choosing the best estimation method and coding the current frame; and updating the global codebook based on the new coded macroblock.

  • Patent number: 6804403
    Abstract: A region-based system, method and architecture for encoding and decoding digital still images to produce a scalable, content-based, randomly accessible compressed bit stream is disclosed. According to the system raw image data is decomposed and ordered into a hierarchy of multi-resolution sub-images. Regions of interest are then determined. A region mask is defined to identify the regions of interest and then encoded. This data is then sorted on the basis of the magnitude of the multi-resolution coefficients to produce the scalable, content-based randomly accessible compressed bit stream.
