Abstract

The embodiment of the invention discloses a video coding method and device, a video decoding method and device, electronic equipment and a storage medium. The video coding method comprises the following steps: determining a content area where at least one similar target is located in multiple frames of continuous images in video data; establishing a brightness time-varying prediction model of the video data according to the image data of the content area; and performing inter-frame motion prediction and / or intra-frame coding on the video data based on the brightness time-varying prediction model. According to the embodiment of the invention, the method calculates and predicts the change of the brightness of the image block over the time, and effectively solves a problem that the large brightness difference of a part of scenes affects the searching and coding efficiency.

Description

technical field [0001] The present application relates to the technical field of multimedia processing, and in particular to a video encoding and decoding method, device, electronic equipment and storage medium. Background technique [0002] Video is a dynamic image sequence formed by connecting pictures one by one. If every pixel data of each picture is directly stored, the bandwidth occupied by the video code stream will be immeasurable. The function of video codec is to compress and digitally encode the image after the camera captures the image to obtain a more optimized code stream with strong anti-interference ability for transmission. In essence, it is to transmit high-quality video data with the smallest possible bandwidth. A series of standards, from MPEG-1 to MPEG-2, from H.263, H.264 to H.265 (HEVC), and now H.266, are all aimed at optimizing the code stream, improving compression efficiency, Greater stability. [0003] Among them, the input of video encoding is...
