Problems solved by technology

[0004] It can be seen that in the related art, it is necessary to calculate the coding cost for each prediction mode by traversing the decision-making prediction modes. However, since the calculation of the coding cost itself is relatively complicated, the computational complexity of calculating the coding cost for all prediction modes is relatively high. High, the processing load of the entire decision-making process of the prediction mode is large, and the efficiency of video coding is low

Abstract

The invention discloses a prediction mode selection method and device, video coding equipment and a storage medium, and belongs to the technical field of video coding. The method comprises the following steps: obtaining a pre-analysis motion vector of a down-sampling unit corresponding to a to-be-coded unit, wherein the down-sampling unit is obtained by performing down-sampling and division on a current coding frame where the to-be-coded unit is located; determining M candidate motion vectors according to motion vectors respectively corresponding to at least two coded units adjacent to the to-be-coded unit in the current coding frame; determining a target motion vector from the M candidate motion vectors according to a current to-be-selected target prediction mode; and when the pre-analysis motion vector and the target motion vector meet a preset condition, determining the target prediction mode as a prediction mode for coding the to-be-coded unit. In combination with the motion information of the pre-analysis stage and the motion features inherited from the adjacent coded units, the prediction mode can be quickly judged, the decision time of the prediction mode is shortened, and the decision efficiency of the prediction mode is improved.

Description

technical field [0001] The present application relates to the technical field of video coding, and in particular to a prediction mode selection method, device, video coding device and storage medium. Background technique [0002] Video coding technology mainly achieves video compression by eliminating redundancy in video signals, among which predictive coding technology is more commonly used. In the process of predictive coding, it is necessary to divide each frame of video image into multiple coding units, and then perform predictive coding on each coding unit respectively. [0003] Before predictive coding is performed on the coding unit, a prediction mode needs to be decided first, that is, an optimal prediction mode needs to be selected from multiple prediction modes defined by video coding standards to perform predictive coding. The method of determining the optimal prediction mode in the related art is: traverse each prediction mode to calculate the coding cost corres...
