Intra-frame coding block division processing method and hardware device

Abstract

The invention discloses an intra-frame coding block division processing method. The method comprises the following steps: acquiring a coding unit to be processed in a video frame; determining a targetprocessing mode corresponding to the to-be-processed coding unit according to the corresponding relationship between the similarity of the texture information at different positions in the coding unit and the processing mode, wherein the target processing mode comprises the step of not dividing the to-be-processed coding units or dividing the to-be-processed coding units by adopting a target division mode; and processing the coding unit to be processed according to the target processing mode. The invention further discloses a hardware device. The invention aims to select the processing mode of the coding unit in real time, simplify the process of dividing the coding unit of the video frame, reduce hardware resources occupied by data processing in the video coding process, and improve theefficiency of completing the division of the video coding unit by hardware.

Description

technical field [0001] The present invention relates to the technical field of video processing, in particular to an intra-frame coding block division processing method and a hardware device. Background technique [0002] In the new generation of audio and video coding standards (such as AVS3, VVC, etc.), the division of coding units adds a more subdivided division mode, which increases the division mode of coding units from the original 2 to 6. In so many In the division mode of the coding unit, in order to ensure the encoding quality, it is necessary to select the best division mode to divide the video frame. [0003] However, currently, when selecting the best division mode for the unit to be divided in the video frame, the encoder sequentially uses multiple selectable division modes to perform subsequent encoding work such as intra prediction, quantization, transformation, and entropy coding on the current coding unit , and then obtain the precoding information of the d...

[0003] However, currently, when selecting the best division mode for the unit to be divided in the video frame, the encoder sequentially uses multiple selectable division modes to perform subsequent encoding work such as intra prediction, quantization, transformation, and entropy coding on the current coding unit , and then obtain the precoding information of the division mode. After obtaining the precoding information of all division modes, the best division mode is selected from the division modes to be selected according to the rate-distortion optimization strategy, which will cause strong Data dependence and delay, occupying more hardware resources, seriously affecting the efficiency of hardware to complete video coding unit division
