Abstract

The present invention provides a new method, device, and computer-readable storage medium for estimating video compression noise by using machine learning. Based on video features such as video bit rate, texture space gradient, and motion time gradient, the compression noise estimation model is used to estimate the Compression noise, and then adaptively adjust the pre-processing algorithm parameters in video pre-processing according to the estimated compression noise, so as to achieve effective video compression. Under the same subjective quality premise, the video coding rate can be greatly reduced; or in Under the same bit rate, the subjective quality of the video can be greatly improved.

Description

technical field [0001] The present invention relates to the technical field of video codec, in particular to the estimation of video compression noise in video codec. Background technique [0002] Video has developed into an important tool for people's entertainment and office work. The popularity of 4K, HDR and other videos and the growth of video transmission requirements have brought huge pressure on storage resources and network bandwidth. The development of various applications has produced various types and quality. These problems have brought strong demands and challenges to video coding and video enhancement technologies. Therefore, video coding technology and video enhancement technology have become research hotspots in academic and industrial circles. [0003] Compression noise, that is, compression distortion, is introduced in the process of video compression encoding. The same video is compressed and coded with different degrees of compression. The greater the ...
