Embodiment Construction
[0041] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.
[0042] Such as figure 1 As shown, the embodiment of the present invention provides a fast and efficient 3D-HEVC method for reducing complexity. First, the encoding information of inter-view, space-time and texture depth is jointly used to extract mode prediction features for the 3D-HEVC encoder. Then optimize the mode prediction mode of the current texture and depth tree block, and thus propose two methods: fast CU depth level range determination method and ad...

The invention provides a fast and efficient 3D-HEVC method for reducing complexity, and the method comprises the steps: firstly starting a decision of a tree block, and exporting prediction variableson the corresponding tree block of space-time, a previously coded view and texture depth; identifying the motion complexity of the adjacent tree block and the current tree block according to the prediction variable, and dividing the current tree block into a static motion tree block and a complex motion tree block; adaptively skipping the CU depth levels of the texture tree block and the depth tree block according to the motion characteristics of the static or complex motion tree block; and calculating the rate distortion cost of the current tree block and the rate distortion cost value of theadjacent tree block according to the prediction variable, skipping unnecessary mode decisions, and terminating mode prediction in advance. By executing the fast CU depth level range determination method and executing the adaptive early termination mode prediction method, the calculation complexity of the 3D-HEVC encoder can be reduced, and the HTM encoding time is effectively saved on the premiseof ensuring the rate distortion cost value performance.
Description
technical field [0001] The present invention relates to the technical field of image processing, in particular to a fast and efficient 3D-HEVC method for reducing complexity. Background technique [0002] 3D High Efficiency Video Coding (3D-HEVC) is the latest HEVC standard development to improve the compression performance of the Multiview Video Plus Depth (MVD) format. It employs several additional encoding tools to better represent associated texture and depth data. In order to improve the coding efficiency of MVD, the latest video standard HEVC has developed 3D High Efficiency Video Coding (3D-HEVC). [0003] To effectively compress MVD data, other tools are designed to exploit dependencies between components. However, those additional encoding tools bring significant computational complexity to the encoder and actually hinder the application, and the complexity of 3D-HEVC becomes a critical issue. Therefore, it needs to further reduce the computational complexity wit...
