Embodiment Construction

[0042] The embodiments of the present application are described below by specific specific examples, and those skilled in the art can easily understand other advantages and effects of the present application from the contents disclosed in this specification.

[0043] Although in some instances the terms first, second, etc. are used herein to describe various elements, these elements should not be limited by these terms. These terms are only used to distinguish one element from another. For example, a first decoder could be referred to as a second decoder, and similarly, a second decoder could be referred to as a first decoder, without departing from the scope of the various described embodiments. Both the first decoder and the decoder are describing a threshold, but unless the context clearly indicates otherwise, they are not the same decoder.

[0044] Also, as used herein, the singular forms "a," "an," and "the" are intended to include the plural forms as well, unless the co...

Abstract

The present application relates to the technical field of image processing, and specifically provides a compression method, decompression method, system and storage medium for obtaining video files, including: obtaining multiple pieces of image data to be compressed in chronological order; The color attribute of the pixel, the color value of each pixel in each image data is mapped to each pixel position in the multiple image blocks; the image corresponding to each image data in the multiple image data and having the same color attribute chunks are compressed to get the video file. The solution provided by the present application can effectively reduce the code stream and ensure high-fidelity image quality at the same time. Since the compression method in the present application can effectively reduce the amount of data, the 8k video can be encoded by the 4K encoder in the prior art. Since the current stable uplink peak value of 5G is 90Mbps, it can realize 5G real-time transmission of 8K video, and at the same time have high-fidelity picture quality.

Description

technical field [0001] The present application relates to the technical field of image processing, and in particular, to a compression method, decompression method, system and storage medium for obtaining video files. Background technique [0002] As people's playing quality of multimedia playing data is getting higher and higher, the data volume of multimedia playing data is also increasing. For multimedia playback data with a large amount of data, after the traditional method is used to compress and encode it, the amount of data still cannot be controlled within the range that can be stably transmitted. In order to ensure that the multimedia playback data can be transmitted stably, the multimedia playback data can usually only be further compressed, but this method will cause serious loss of color information and cannot meet the requirements of high image quality. Therefore, people expect to have a better compression method, so as to achieve a high-fidelity effect for mul...
