Abstract

The invention discloses a code rate allocation method and device. The method comprises the steps that a current frame image is acquired; the current frame image is classified into a salient region and a non-salient region, wherein the saliency measure of the salient region is higher than the saliency measure of the non-salient region; different code rate resources are allocated to the salient region and the non-salient region, wherein code rate resources allocated to the salient region are more than code rate resources allocated to the non-salient region. According to the invention, the technical problem that the effect of a code rate allocation method in the related art is poor relative to human eye perception is solved.

Description

technical field [0001] The present invention relates to the field of image coding, in particular to a code rate allocation method and device. Background technique [0002] Bit rate allocation is an important link in the video coding process, and the number of bits allocated to each frame of image by bit rate allocation largely determines the quality of the encoding. In the case of limited network bandwidth resources, how to balance bit rate allocation and video quality has become a hot issue for many researchers. In H.264, the compression effect is generally evaluated by parameters such as PSNR (Peak Signal to Noise Ratio) and SSIM (Structural Similarity Index) after video compression, but the values ​​of these parameters can only reflect The overall situation of the video cannot meet the requirements for the obvious perception of the human eye. [0003] In the traditional bit rate control method, the principle of bit rate allocation takes into account the complexity of th...
