Coding mode selection method and device, electronic equipment and computer readable medium

Abstract

The embodiment of the invention provides an encoding mode selection method and device, electronic equipment and a computer readable medium. The method comprises the following steps: respectively estimating a symmetrical inter-frame prediction mode and a motion merging prediction mode for a prediction unit to obtain rate distortion costs of the symmetrical inter-frame prediction mode and the motionmerging prediction mode; determining a first candidate prediction mode according to the rate-distortion cost of the symmetric inter-frame prediction mode and the rate-distortion cost of the motion merging prediction mode; determining a second candidate prediction mode set from the asymmetric inter-frame prediction modes according to the first candidate prediction mode; carrying out candidate asymmetric inter-frame prediction mode estimation to obtain the rate distortion cost of a second candidate prediction mode set; and determining a target prediction mode of the target coding unit accordingto the rate-distortion costs of the first candidate prediction mode and the second candidate prediction mode set. According to the technical scheme, the second candidate prediction mode set is determined under the guidance of the first candidate prediction mode, the operation data volume can be effectively reduced, and the encoding speed is increased.

Description

technical field [0001] The present disclosure relates to the field of natural language processing, in particular, to a coding mode selection method, device, electronic equipment and computer readable medium. Background technique [0002] The future development trend of video is high definition, high frame rate, and high compression rate. The current popular compression methods have certain limitations in principle and cannot meet future needs. Therefore, various encoding protocols suitable for video compression should be used. And born. However, the current encoding protocol is relatively complex and requires relatively high machine performance. When applied to ordinary machines, its encoding speed is relatively slow, and real-time encoding cannot be realized. For example, the current encoding protocol requires traversal of each encoding mode, so as to determine the optimal encoding mode in each encoding mode according to the traversal result. The above-mentioned complica...
