Embodiment Construction

[0031] The technical solutions in the embodiments of the present invention will be described below with reference to the drawings in the embodiments of the present invention.

[0032] The technical solutions provided by the embodiments of the present invention are applicable to scenarios of inter-frame predictive coding.

[0033] Inter-frame prediction is to use the correlation of the video time domain to predict the pixels of the current image using the pixels of the adjacent coded image, so as to effectively remove the redundancy of the video time domain.

[0034] The essence of inter-frame predictive coding is to obtain the coding block in the video data that is relatively similar to the block to be coded, call the coded block a matching block, and calculate the motion vector between the block to be coded and the matching block, and convert the block to be coded The motion vector between it and the matching block is called the target motion vector; the prediction informatio...

Abstract

The invention provides a video coding method and device, electronic equipment and a storage medium. The method comprises the following steps: respectively calculating the rate distortion cost of a to-be-coded block in a merge mode and a first AMVP mode, wherein the first AMVP mode is motion estimation of 1 / 4 pixel precision in the AMVP mode; when the preferred mode determined based on the rate distortion cost is a skip mode in the merge mode, judging whether the coding index of the first AMVP mode is smaller than a preset threshold value or not; when the coding index of the first AMVP mode issmaller than a preset threshold value, determining that the target coding mode is a skip mode; and encoding the block to be encoded according to the target encoding mode. According to the invention, the coding time can be reduced and the coding efficiency can be improved.

Description

technical field [0001] The present invention relates to the technical field of coding, in particular to a video coding method, device, electronic equipment and storage medium. Background technique [0002] In video coding, video is an image sequence formed by continuous image frames. Due to the limitation of scene change speed, there is a high correlation between adjacent frames, that is, there is high temporal redundancy. Motion estimation in the inter-frame predictive coding method is to use the correlation between adjacent frames in the video image sequence to establish the expressive relationship between adjacent frames, thereby reducing time redundancy and improving video coding efficiency. an important method. [0003] In the previous generation of video coding standards, such as the High Efficiency Video Coding (HEVC) standard, the motion estimation process only supports motion estimation with 1 / 4 pixel precision. In the new generation of video coding standards, mot...
