Abstract
A reduced-complexity but effective search scheme for rate-distortion (RD) optimisation of motion vector and displaced-frame-difference coding is proposed. Through predicting the relative order of the RD-Lagrange costs, a large proportion of suboptimal displacement vector positions are eliminated. In comparison with a popular H.263 test model, the proposed scheme leads to a ~0.5 dB improvement in the peak signal-to-noise ratio
