Abstract

The invention provides a method for multi-viewpoint video coding side information integration, which comprises the following steps: a reference frame step: at a moment point, obtaining a target frame at a standard viewpoint, and simultaneously obtaining a first reference frame and a second reference frame respectively at a first reference viewpoint and a second reference viewpoint near the standard viewpoint; obtaining a front reference frame at the standard viewpoint before the moment point and obtaining a rear reference frame after the moment point; a motion estimation step: respectively estimating a front estimation frame and a rear estimation frame by adopting a motion estimation mode, and obtaining the weighted value of the front estimation frame and the rear estimation frame as a time estimation frame; a parallax estimation step: respectively estimating a first estimation frame and a second estimation frame by adopting a parallax compensation mode, and obtaining the weighted value of the first estimation frame and the second estimation frame as a space estimation frame; and a side information estimation step: constructing a membership function, and obtaining the membership function values of the time estimation frame and the space estimation frame to obtain side information.

Description

Technical field [0001] The invention relates to a method for multi-viewpoint video coding side information fusion. Background technique [0002] In recent years, traditional video coding technologies have encountered bottlenecks in applications such as wireless sensor networks, and how to reduce the computational burden on the coding end has become an important issue. In response to this problem, the distributed video encoding technology proposed by scholars can shift the computational burden from the encoding end to the decoding end. At the same time, multi-viewpoint video can observe scenes from multiple different perspectives and can obtain richer information, making multi-viewpoint video coding widely used in many fields such as education, entertainment, and production. [0003] In distributed video coding, the quality of side information is an important factor related to system performance. Similarly, in the research of distributed multi-view video coding, how to obtain high-...
