Problems solved by technology

The current standard generally adopts the frame of single-view coding for processing, but it does not actually consider the characteristics of the double spelling attribute of the signal source. As a result, the performance of double spelling stereoscopic video coding is very low

Abstract

The invention provides a motion estimation method and device for dual-spelling stereo video coding, the method comprising the steps of: down-sampling a first path of video sequence and a second path of video sequence, and splicing the first path of down-sampled image sequence and the second path of down-sampled image sequence; selecting a current block a1, and acquiring an initial matching block set; up-sampling the a1 and the initial matching block set, and searching for a current block a2 corresponding to the a1; calculating a difference value and energy between the a2 and each matching block, and acquiring a motion vector between each matching block and the current block a2; calculating a difference value block between the a1 and a matching block b2, and coding; and splitting a restructured dual video sequence, and up-sampling the split image sequences so as to obtain restructured binocular video sequences corresponding to the first path of video sequence and the second path of video sequence. By utilizing the embodiment of the invention, the method is more precise to code and better in coding compression property. The device is simple in structure and easy to carry out.

Description

technical field [0001] The present invention relates to the technical fields of computer vision and video processing, in particular to a motion estimation method and device for Shuangpin 3D video coding. Background technique [0002] In recent years, with the popularization of 3D stereoscopic applications, research on stereoscopic images and videos has become a hot topic. Since the data volume of original images and videos is very large, and the bandwidth cannot be increased without limit, in order to use the limited network bandwidth to complete the image transmission of large data volumes, effective video compression technology has become one of the research hotspots at home and abroad. [0003] For the stereoscopic video coding of Shuangpin, the prior art still maintains a single-view coding mode, and there is no standardized and targeted unified coding mode. The current standard generally adopts the frame of single-view encoding for processing, but actually does not con...
