Embodiment Construction

[0029] The present invention will be described in detail below in conjunction with the embodiments and accompanying drawings, but the present invention is not limited thereto.

[0030] like figure 1 As shown, a fast selection method for multi-view video coding inter-view prediction, comprising the following steps:

[0031] (1) Input multi-viewpoint video data and depth information;

[0032] (2) Macroblock intra-mode estimation;

[0033] (3) Active calculation of macroblock inter-mode division;

[0034] (4) Depth information texture complexity calculation of macroblocks in 16x16, 16x8, 8x16, 8x8 division modes;

[0035] (5) Inter-view prediction selection for each small-size inter-mode in the macroblock;

[0036] The intra-frame modes include Intra16x16, Intra8x8, and Intra4x4; the small-size inter-frame modes include: Inter16x8, Inter8x16, and Inter8x8.

[0037] Step (3) is specifically:

[0038] Utilize the best intra-mode obtained in step (2), calculate the inter-mode ...

Abstract

The invention provides a fast selection method of inter-view prediction for multi-view video coding (MVC). The fast selection method comprises the following steps: (1) inputting MV data and depth information; (2) estimating intra-frame modes of macroblocks; (3) calculating partition activity of inter-frame modes of the macroblocks; (4) calculating the texture complexity of the depth information of the macroblocks under partition modes such as 16*16, 16*8, 8*16 and 8*8; and (5) selecting inter-view prediction for each small-size inter-frame mode in the macroblocks. The fast selection method provided by the invention is applicable to selecting inter-view prediction for MVC; and by adopting the method, the overall computation quantity for MVC can be reduced and meanwhile distortion performance of the coding rate can be maintained.

Description

technical field [0001] The invention relates to the field of digital video coding, in particular to a fast selection method for inter-viewpoint prediction of multi-viewpoint video coding. Background technique [0002] Multiview Video (MV) is the video data obtained by shooting the same scene with cameras in different positions. It contains rich visual information and can be applied to 3D TV, free viewpoint TV, video surveillance, virtual reality and other fields. . Multiview Video Coding (MVC) efficiently compresses multiview video data to solve the problem of storage and transmission of its huge data volume. The Joint Video Team (JVT) has completed the standardization of multi-view video coding as the fourth addition to H.264 / AVC (see ITU-T and ISO / IEC JTC 1, Advanced video coding forgeneric audiovisual services, that is, "Advanced Video Coding for Audio and Video Services", ITU-T Recommendation H.264 and ISO / IEC 14496 (MPEG-4 AVC), 2010). In order to improve the coding ...
