Matching-pursuit video coding .II. Operational models for rate and distortion
For pt. I see ibid., vol.12 , no.1, (2000).We introduce two models for predicting the rate and distortion of the matching-pursuit video codec. The first model is based on a pre-coding analysis pass using the full matching-pursuit dictionary. The second model is based on a reduced-complexity analysis pass. We evaluate these models for use within existing rate-distortion optimization techniques. Our prediction results suggest that the models have sufficient accuracy to be useful in this context, and that significant complexity reductions could be achieved compared to exact rate-distortion computation.
