Abstract
The paper illustrates a method for affine warping based motion compensation that exploits the same prediction mechanism as the H263 Advanced Prediction Mode, only introducing new constant weighting matrices in the H263 Overlapped Motion Compensation algorithm. In particular we show that, with reference to a regular-mesh based motion estimation algorithm, image prediction using affine morphing can be easily performed with fixed coefficients, when a proper linear resampling is used. The performance of a H263-like coder based on affine transformation and linear resampling is illustrated through experimental data.
