Abstract

The invention relates to a video frame processing method and device, computer equipment and a computer readable storage medium, and the method comprises the steps: calculating the complexity of each to-be-processed original video frame according to the width, height, QP value and image two-dimensional entropy information of the original video frame for different to-be-processed original video frames in a preprocessing stage; and selecting a preset sampling magnification to carry out adaptive down-sampling on the original video frame to be processed to obtain an initial video frame according to the complexity. In the preprocessing stage, for different video frames, different multiplying powers are selected for down-sampling according to the complexity of the video frames, the higher the complexity of the video frames is, the higher the sampling multiplying power is, and the video quality is ensured while the code stream size of the video is reduced.

Description

technical field [0001] The present application relates to the technical field of video encoding and decoding, and in particular to a video frame processing method, device, computer equipment and computer-readable storage medium. Background technique [0002] With the development of digital media technology and computer technology, video is used in various fields, such as mobile communication, network monitoring, network TV and so on. With the improvement of hardware performance and screen resolution, users' demand for high-definition video is increasingly strong. The higher the high-definition video, the higher the bit rate, and the higher the requirements for the network. Under the low bit rate channel, there is the problem of difficult high-definition video transmission. [0003] Existing technologies generally use static video preprocessing decisions, that is, uniform sampling preprocessing is performed on video frames before encoding to ensure video quality at low bit ...
