Embodiment Construction

[0023] In order to make the purpose, technical solution and advantages of the present application clearer, the present application will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present application, and are not intended to limit the present application. Meanwhile, in the description of the present application, the terms "first", "second" and the like are only used to distinguish descriptions, and cannot be understood as indicating or implying relative importance.

[0024] Digital images may be polluted by noise in the process of acquisition and transmission. Common noises mainly include Gaussian noise and salt and pepper noise. Among them, Gaussian noise is mainly generated inside the camera sensor components, salt and pepper noise is mainly black and white bright and dark point noise generated by image cutting, "pepper" me...

Abstract

The application belongs to the technical field of image processing, and particularly relates to an image denoising method and device, a terminal and a computer readable storage medium. The method comprises the steps of: partitioning a to-be-processed high-resolution image into a plurality of first image blocks; carrying out denoising processing on each first image block by utilizing a trained generative adversarial network, and generating a denoised second image block corresponding to each first image block; and carrying out splicing on all the second image blocks to obtain a denoised first high-resolution image. Image distortion caused by image denoising processing is efficiently reduced, image quality is improved, and meanwhile, an image denoising processing speed is improved.

Description

technical field [0001] The present application belongs to the technical field of image processing, and in particular relates to an image denoising method, device, terminal and computer-readable storage medium. Background technique [0002] In the process of image acquisition and transmission, various noises will be superimposed, such as salt and pepper noise and Gaussian noise, etc., which seriously affect the image quality. [0003] At present, there are bilinear filtering, median filtering and wavelet transform methods to remove noise. However, these image denoising methods may cause image distortion while removing image noise, and cannot effectively improve image quality. Contents of the invention [0004] Embodiments of the present application provide an image denoising method, device, terminal, and computer-readable storage medium, which can solve the technical problem of removing image noise while causing image distortion. [0005] The first aspect of the embodiment...
