Embodiment Construction

[0049] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0050] The main process of the solution of the present invention is to first obtain the motion information of the current CU in the 2Nx2N Merge mode, and use the information to determine whether it is necessary to perform the FRUC Merge mode. If the 2Nx2N Merge mode is enough to match, it is unnecessary to perform the FRUC Merge mode. After testing multiple sequences, the judgment accuracy reaches more than 95%. Due to the spatial correlation of the video content, and through the test, it is found that the time of the Bilateral mode in the FRUC Merge mode is relatively large, so it is judged whether to use the Bilateral mode based on the mode information of the adjacent blocks in the airspace. Finally, the calculation in Bilateral mode is simplified by the motion vector obtained in 2Nx2N mode.

Abstract

The invention discloses a video coding Merge mode rapid selection method and a video coding Merge mode rapid selection device based on time-space domain correlation. In the method, a FRUC Merge mode is ended in advance via the information of a time domain and a space domain, computation complexity of the FRUC Merge is simplified according to motion information, so that coding time is greatly reduced while coding quality is ensured. The method and the device provided by the invention are simple and easy to use and simple in structure, and greatly improve practicability of JEM.

Description

technical field [0001] The invention belongs to the field of video decoding, in particular to a method and device for quickly selecting a video coding Merge mode based on time-space domain correlation. Background technique [0002] FRUC (Frame-Rate Up Conversion) is a technology for converting any two video display formats with different frame rates. In addition, FRUC can also be applied to low bit rate video coding (LBR). Many scholars in the field of video coding have already studied FRUC technology, and recently, in the formulation of a new generation of video coding standards, FRUC was proposed again and applied in new standards. [0003] In 2015, ITU-T VCEG and ISO / IEC MPEG established an expert group JVET to start research on a new video coding standard whose compression rate will significantly exceed the existing HEVC standard. JEM, as the latest encoding software that is currently hotly discussed, still uses the HEVC framework in the encoding framework, including m...
