Problems solved by technology

[0004] However, since the distribution of pixel values ​​in the image may have specific rules, for example, the content displayed in the image is black and white stripes, and the pixel values ​​​​of adjacent pixels are arranged at intervals of 0 and 1. If the sampling method used is interval sampling, that is, every One pixel is sampled once, and the pixel values ​​of the sampled pixels are all 0 or 1, resulting in that the compressed image cannot accurately express the information in the original image.

Abstract

The present disclosure relates to an image compression method, comprising: determining the distribution law of pixel values ​​of pixels in an image; if the distribution law conforms to a preset distribution law, changing the distribution law of the pixel value by a preset method; according to the changed pixel value Regularly distributed images generate compressed images. According to the embodiments of the present disclosure, by changing the distribution law of pixel values, the image after the change can reduce the regularity of the distribution of pixel values ​​compared with the image before the change. The impact of the value distribution makes the compressed image unable to accurately express the information in the original image, which is beneficial to ensure that the compressed image can express the information in the original image relatively accurately.

Description

technical field [0001] The present disclosure relates to the technical field of image processing, and in particular to an image compression method, an image compression device, electronic equipment, and a computer-readable storage medium. Background technique [0002] With the update and progress of image acquisition equipment, the resolution of the collected images is getting higher and higher, which leads to an increase in the amount of image data. [0003] However, in some cases, an image with a very high resolution is not required. In order to reduce the amount of image data in related technologies, image compression is mainly realized by sampling. [0004] However, since the distribution of pixel values ​​in the image may have specific rules, for example, the content displayed in the image is black and white stripes, and the pixel values ​​​​of adjacent pixels are arranged at intervals of 0 and 1. If the sampling method used is interval sampling, that is, every One pix...
