Motion based object tracking in MPEG-2 stream for perceptual region discriminating rate transcoding
Javed I. Khan, Guo Zhong, Wansik Oh · 2001
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.
