Abstract
Classical matching criteria for motion estimation determine the match quality by operating in the spatial domain. The resulting displaced frame difference signal is, however, compressed by means of frequency transformations, and any optimal matching criteria should estimate the cost of coding the composite bit stream. Such criteria are presented in this paper and shown to offer some improvement in the PSNR of the reconstructed sequence
