VIDEO ENCODER WITH LOW COMPLEXITY NOISE REDUCTION

摘要

Noise reduction is achieved during video encoding with low complexity by making use of the motion estimation decision sets for noise reduction. Motion estimation is performed N times (where N is integer) on each macroblock to yield N sets of motion estimation data, each set including a reference picture index and a motion vector. Typically, although not necessarily, each set of motion estimation data makes use of a different reference picture. For each macroblock, the N sets of motion estimation data are used to create a noise-reduced macroblock, which is then encoded.
