Abstract

The invention discloses a method, a device and equipment for removing human eye perception redundant video codes. The method comprises the following steps: simulating perception characteristics of a human eye vision system to calculate a perception redundant threshold; and modulating the quantization coefficient to suppress the image. According to the method, the influence of quantization distortion in video coding on perception distortion is fully considered, multi-dimensional perception redundancy threshold values are calculated by simulating perception characteristics of a human eye visionsystem, different modulation coefficients are set according to different quantization QPs, and overlapping of the quantization distortion and the perception distortion is effectively reduced.

Description

technical field [0001] The present invention relates to the field of video, in particular to a method, device and equipment for removing redundant video coding perceived by human eyes. Background technique [0002] In current video coding, the compression ratio of video coding based on objective quality has reached its limit. In order to meet people's higher requirements for video quality, more and more people have begun to study perceptual video coding based on subjective quality evaluation. Perceptual video coding has become a research hotspot. At present, most of the texture complex calculations for perceptual video coding use the traditional Sobel operator and Gabor filter, and the characteristics of the encoder itself are not well considered. The main problems are as follows: [0003] (1) Video coding based on objective quality cannot well meet the current various new types of high-resolution ultra-high-definition video services; [0004] (2) The current perceptual vi...
