Abstract

The invention belongs to the technical field of three-dimensional video image processing, and particularly relates to an advanced residual error prediction method based on a reconfigurable array processor. The method comprises the following steps: acquiring texture image data and corresponding depth image data of a current coding unit of a texture image to be coded; when the depth data of the current coding unit belongs to a depth range in a pre-obtained advanced residual error prediction rule, obtaining an advanced residual error prediction algorithm of the current coding unit through matching of the advanced residual error prediction rule; performing predictive encoding on the texture image data of the current encoding unit by adopting the obtained advanced residual prediction algorithm,wherein the advanced residual prediction rule is obtained by counting an advanced residual prediction algorithm adopted by a video test image coding unit, and the video test image and the texture image to be coded belong to the same scene. The method is low in calculation complexity and short in coding time, and meets the real-time coding requirements of video images in a multimedia system.

Description

technical field

[0001] The application belongs to the technical field of three-dimensional video image processing, and in particular relates to an advanced residual prediction method and an array processor based on a reconfigurable array processor. Background technique

[0002] Three-dimensional high-efficiency video coding (3-Dimensional-High Efficiency Video Coding, 3D-HEVC) is an extension of the HEVC standard for two-dimensional video coding, which is used for coding multi-view video and depth maps. Prediction, DCP), Advanced Residual Prediction (Advanced Residual Prediction, ARP) and other advanced coding tools to reduce redundant information between viewpoints.

[0003] The core of the new ARP algorithm in the 3D-HEVC inter-view prediction algorithm is to use the residual information between views to reduce the redundancy between views. The principle of ARP is as follows figure 1 As shown, where V0 represents the base view, V1 represents the non-base view, Dc represe...
