Video coding method and device, video decoding method and device, electronic equipment and storage medium

Abstract

The invention discloses a video coding method and device, a video decoding method and device, electronic equipment and a storage medium, and the coding method comprises the steps: carrying out the feature extraction of a video according to a current video analysis task, so as to extract video feature information; determining feature value information of an image in the video based on the video feature information, and generating segmentation information and recombination information of the image in the video through the feature value information; carrying out segmentation processing on an image in the video based on the segmentation information so as to segment the image into a plurality of image blocks; performing recombination processing on the image blocks based on the recombination information to generate a recombined image; and compressing the recombined image to obtain a video data stream, sending the feature data stream and the video data stream, and transmitting the segmented and recombined information through the feature data stream. According to the method, corresponding coding and transmission parameters are applied to the video data according to the features extracted by the video analysis task, so that efficient coding and decoding are realized.

Description

technical field [0001] The present invention relates to the technical field of video coding, and more specifically, the present invention can provide video coding, video decoding methods and devices, electronic equipment, and storage media. Background technique [0002] Block-based video codec technology has the characteristics of mature technology and moderate computational complexity, so it has developed very rapidly in the past few decades. Currently, mainstream codec technologies include H.264 / H.265 / H.266 and MPEG2 / MPEG4, etc., all of which rely on block-based video codec technologies. However, the implementation of traditional block-based video codec technology is based on human visual perception, for example, it is highly dependent on the insensitivity of human eyes to high-frequency information, which leads to block-based video codec technology for high-frequency information in video data. The frequency components are compressed to a greater extent. [0003] However...
