Abstract
A FAP coding technique that realizes enough coding gain to transmit multiple synthetic talking heads over a band limited channel without introducing perceptible artifacts into the reconstructed synthetic talking heads. This is accomplished by exploiting the spatial correlation of each FAP frame and/or the temporal correlation of the sequence of FAP frames. To remove intra-frame correlation, each FAP frame is transformed prior to segmentation from the n-dimensional space into an m-dimensional subspace where m<n using an energy compaction transform. To remove inter-frame redundancy, the sequence is segmented and each parameter vector is transform coded to decorrelate the vector.
