Abstract:
1. An processing apparatus for motion-compensated video encoding, comprising: (a) means for providing a frame in a video sequence for motion-compensated encoding; (b) for a pixel in said frame, means for comparing a difference between (i) the value of said pixel and (ii) the predicted value of said pixel from motion compensation prediction of said frame to a first level; (c) when said comparing of step (b) indicates said difference is greater than said first level, means for applying lowpass filtering to said pixel; (d) for said pixel, means for comparing said difference to a second level which is less than said first level; (e) when said comparing of step (d) indicates said difference is greater than said second level but less than or equal to said first level, means for comparing the magnitude of the motion vector for the block containing said pixel to a first threshold; (f) when said comparing of step (e) indicates the magnitude of said motion vector is greater than said first threshold, means for spatial lowpass filtering to said pixel; and (g) motion-compensated encoding of said frame after said filtering, wherein said filtering of step (c) is both spatial in said frame and temporal over other frames of said video sequence.
