Abstract
Described herein is a method and system for video classification. The method and system can use predetermined color ranges to classify a video block. On a relative basis, a greater number of bits can be allocated to perceptually important video data such as skin. The quantization is adjusted accordingly. Determining relative quantization shifts for macroblocks in a picture prior to video encoding enables a corresponding bit allocation that can improve the tradeoff between perceptual quality and bit rate.
