1. A method of coding facial animation parameters (FAPs) for synthetic video, comprising:

  • generating a temporal sequence of FAP frames for a synthetic video signal, each said frame representing a time sample of spatially correlated parameters in an n-dimensional space;

    transforming each said FAP frame from the n-dimensional space into an m-dimensional subspace where m<

    n to reduce the intra-frame spatial correlation; and

    coding the temporal sequence of m-dimensional FAP frames into a bitstream.
