Content, psychovisual, region of interest, and persistence based adaptive quantization for video coding

摘要

Techniques related to improved video encoding including content, psychovisual, region of interest, and persistence based adaptive quantization are discussed. Such techniques may include generating block level rate distortion optimization Lagrange multipliers and block level quantization parameters for blocks of a picture to be encoded and determining coding parameters for the blocks based on a rate distortion optimization using the Lagrange multipliers and quantization parameters.
