1. A method for replacing original texture in a set of frames included in a video sequence with synthesized texture such that a bit rate of the video sequence that includes the synthesized texture is less than a bit rate of the original video sequence, the method comprising:

  • selecting original texture from an initial frame within the set of frames;

    removing the selected original texture from the set of frames in the video sequence;

    determining texture parameters from an analysis of the removed texture; and

    inserting synthesized texture, based on the texture parameters, into the set of frames, the inserting synthesized texture into the set of frames, further comprising;

    synthesizing the removed texture by;

    applying, in a prescribed order, coefficient magnitude correlations, cross scale statistics, coefficient correlations, marginal statistics, overall color, and color saturation qualitative constraints if the original texture is structured and busy; and

    applying, in a prescribed order, coefficient magnitude correlations, cross scale statistics, overall color, and color saturation qualitative constraints if the original texture is unstructured and smooth.
