Abstract

Abstract: The motion vectors and macroblock type during video transcoding based on resolution reduction are refined in this paper. A model of adaptive motion vectors is proposed based on the sum of the differential quantization errors, thus to reduced the search area. It is possible to achieve fast motion estimation for near-optimal outgoing motion vectors. This method may improve the computational complexity without significant losing in quality.

Key words: transcoding, resolution reduction, adaptive, motion estimation, video
