Embodiment Construction

[0028] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0029] The present invention designs a fast decision-making method for an inter-frame coding merging mode for a CU of a 3D video non-independent viewpoint texture map. In actual use, the encoder will call the method of the present invention to complete specific encoding work. image 3 It is a flowchart of the method of the present invention. Definition J skip (CU cur ) represents the rate-distortion cost obtained by encoding the current CU with merge-skip mode, Jmerge (CU cur ) represents the rate-distortion cost obtained by encoding the current CU in merge mode. Method steps of the present invention are as follows:

[0030] Step 1: Read in the video sequence according to the configuration file of the encoder, and configure the encoder through the parameter information in the configuration file.

[0031] Step 2: sequentially extract the CUs to be coded ...

Abstract

The present invention discloses a fast decision-making method for 3D-HEVC inter-frame coding merging mode. 1) Extract CUs to be coded from texture maps of dependent viewpoints. 2) The current CU checks merge mode and merge-skip mode in 2Nx2N partition mode. 3) Determine whether the frame where the current CU is located is a P frame or a B frame. 4) Through the judgment of the previous step, if the obtained result is a P frame, judge whether the division level of the current CU is 3 and whether the condition a and condition b are satisfied at the same time; 5) Through the judgment of step 3, if the obtained result is a B frame, The 5 reference blocks of the current CU in the view direction are determined by the disparity vector (DoNBDV) obtained from the adjacent blocks, including the corresponding block of the current CU in the view direction and its 4 adjacent blocks. Judging whether the current CU satisfies condition c and condition d at the same time: the method of the present invention can save an average of about 6.5% of total encoding time and 20.4% of non-independent view texture map encoding time while ensuring encoding quality.

Description

technical field [0001] The present invention relates to the technical field of video coding, in particular to a method for fast decision-making of an inter-frame coding combination mode in the 3D video coding standard 3D-HEVC based on the high-efficiency video coding standard HEVC. Background technique [0002] The High Efficiency Video Coding standard (HEVC) was jointly established by the International Organization for Standardization / International Electrotechnical Commission (ISO / IEC) Moving Picture Experts Group (MPEG) and the International Telecommunication Union Telecommunication Standardization Organization (ITU-T) Video Coding Experts Group (VCEG). A new generation of video coding standard formulated by the Joint Video Coding Working Group (JCT-VC), its official name in ISO / IEC is the second part of the MPEG-H standard, and its official name in ITU-T is H.265 . With the continuous improvement and development of HEVC, MPEG and VCEG established the 3D Video Coding Join...
