摘要
Preprocessing for motion-compensated video encoding such as MPEG includes lowpass filtering, temporal (310) and/or spatial (312), locally per pixel in response to motion vector analysis and prediction error (304) and temporal change (306). This de-emphasizes image areas of rapid change which corresponds to human perception de-emphasis.
