Embodiment Construction

[0062] Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, the same numerals in different drawings refer to the same or similar elements unless otherwise indicated. The implementations described in the following exemplary examples do not represent all implementations consistent with the present disclosure. Rather, they are merely examples of apparatuses and methods consistent with aspects of the present disclosure as recited in the appended claims.

[0063] The compression quality obtained by processing the same image with different compression algorithms is different. The embodiment of the present disclosure provides an image processing method. For an image to be compressed, the compression algorithm with the best compression quality can be selected from several compression algorithms for compression. good question.

Abstract

The invention provides an image processing method and device, which relate to the technical field of image processing and can solve the problem of poor compression quality of a single image compression algorithm for different types of images. The specific technical scheme is as follows: obtaining the target image; determining an image class of the target image through a neural network classification model; determining a target algorithm according to preset mapping data; and compressing the target image according to the target algorithm. The present disclosure is for image processing.

Description

technical field [0001] The present disclosure relates to the technical field of image processing, and in particular, to an image processing method and device. Background technique [0002] Natural images usually have uniform and excessive colors, and there will be no step-type image information. Therefore, for natural images, the method of prediction plus frequency domain transformation is usually used for image compression, which can obtain better compression quality. [0003] Different from natural images, artificially generated images have their own characteristics. Firstly, the noise is controllable, and noise-free images can be generated; secondly, the image contains a large number of high-gradient signals, such as text and lines. If these high-gradient images are compressed by the traditional method of prediction plus frequency domain transformation, the compression effect is often not good compared with natural images. [0004] It can be seen that an image compress...
