Embodiment Construction

[0021] The following description is the preferred embodiment of the present invention. The general terms are used to describe the invention but not to limit the scope of the invention. The scope of protection of the present invention should be defined by the appended claims.

[0022] As mentioned above, the adaptive block partitioning disclosed by Shimizu has the problem of high complexity and irregular memory access for larger PU sizes. Therefore, the present invention provides a partitioning method for determining view synthesis prediction of PUs. image 3 It is a schematic diagram showing that the entire prediction unit is uniformly partitioned according to a single partition decision according to an embodiment of the present invention. In one example, an 8x8 block of a PU with a size of 32x32 is divided into 8x4 sub-blocks (e.g. image 3 as shown on the left) or 4x8 sub-blocks (such as image 3 shown on the right). For convenience, each divided unit block is referred ...

Abstract

The invention provides a method and device for encoding or decoding a three-dimensional or multi-view video by means of view synthesis prediction. The method for encoding or decoding three-dimensional or multi-view video by means of view synthesis prediction includes the steps of receiving input data related with a current texture block in a related view, positioning a depth block in a reference view related to the preceding texture block by means of obtained disparity vectors, obtaining a single partition decision of the preceding texture block by means of the depth block, and dividing partition blocks of the current texture block into multiple sub blocks according to the single block decision. By means of the method and device for encoding or decoding the three-dimensional or multi-view video by means of view synthesis prediction, partition complexity can be effectively reduced and regular storage is achieved.

Description

technical field [0001] The present invention relates to a 3D video coding, and in particular to a method for optimizing view synthesis prediction (VSP) in a 3D coding system. Background technique [0002] Three-dimensional (3-dimensional, 3D) stereoscopic television is a trend of technological development in recent years, and its purpose is to bring viewers an amazing visual experience. Various technologies have been developed to enable 3D stereoscopic viewing, and multi-view video is the main technology of 3D stereoscopic television. Since all cameras capture the same scene from different views, multi-view video includes a large amount of view redundancy. In order to utilize view redundancy, 3D coding tools, such as view synthesis prediction, have been integrated into commonly used 3D High Efficiency Video Coding (HEVC) or 3D Advanced Video Coding (AVG). [0003] figure 1 The basic concept of VSP in 3D High Efficiency Video Coding Test Model (3D-HEVC Test Model, 3DV-HTM)...
