摘要

基于对象的比特分配可以显著提高相对低比特率视频的感知质量。本文描述了一种新颖的内容感知视频转码技术，该技术可以接受视频对象的高级描述，并从传入视频流中提取视频对象，并将其用于基于感知编码的极端视频降阶。

Motion based object tracking in MPEG-2 stream for perceptual region discriminating rate transcoding

Object based bit allocation can result in significant improvement in the perceptual quality of relatively low bit-rate video. In this paper we describe a novel content aware video transcoding technique that can accept high-level description of video objects and extract them from incoming video stream and use it for perceptual encoding based extreme video downscaling.
