Problems solved by technology

For the current CU, the encoder needs to traverse all the division methods allowed, and determine the optimal division method according to the rate-distortion cost of each division method. Although this traversal division method can accurately find the optimal division method, but It will multiply the complexity of the encoding side

Abstract

The present invention discloses a Gabor-based fast decision method, device and medium for CU division. The method includes: acquiring a block area of ​​a current coding unit; when the block area satisfies a preset first condition, executing the current coding unit vertical filtering processing and horizontal filtering processing to obtain a vertical filtering image and a horizontal filtering image of the current coding unit; calculating the first energy of the vertical filtering image and the second energy of the horizontal filtering image; according to the The first energy and the second energy determine a target division mode; the current coding unit is divided according to the target division mode. In the embodiment of the present invention, the current coding unit is filtered in the horizontal and vertical directions respectively, and the horizontal and vertical texture features thereof are extracted respectively, and the division method in the horizontal or vertical direction is skipped according to the difference of the texture, which can reduce the division It can be widely used in the field of data processing technology.

Description

technical field [0001] The present invention relates to the technical field of data processing, in particular to a Gabor-based fast decision method, device and medium for CU division. Background technique [0002] The China Audio Video Coding Standard (AVS) Working Group was established in 2002 to provide high-quality standards for the compression, decompression, processing and representation of digital audio and video. With the advent of the 5G communication era, new application scenarios such as 4K / 8K ultra-high-definition video, virtual reality (VR) video, and cloud gaming have put forward demands on video coding technology. The AVS working group started the formulation of the third-generation audio and video coding standard (AVS3), which is based on the international VVC (Versatile Video Coding) standard, and completed the preliminary formulation in March 2019. [0003] Compared with the previous generation of video coding standards AVS2 and HEVC, AVS3 has added many ne...
