Abstract

The embodiment of the invention discloses an image denoising method and device and a storage medium, belongs to the technical field of image processing, and can solve the problems that the denoising process is high in complexity and the denoised image is poor in display effect. The method includes: determining at least two fusion weights according to component information of a first component of at least one pixel in a first image block, wherein the at least two fusion weights comprise the fusion weight of the first image block and the fusion weight of the at least one reference image block, the first image block is any image block in the first image, and the first image block comprises one or more pixels; and for each component in the R component, the G component and the B component, according to the at least two fusion weights, weighting the component value of the at least one pixel and the component value of the pixel corresponding to the position in each reference image block of the at least one reference image block to obtain a target component value of the R component, the G component and the B component corresponding to the at least one pixel.

Description

technical field [0001] The present application relates to the technical field of image processing, and in particular to an image denoising method, device and storage medium. Background technique [0002] In the existing RGB spatio-temporal joint denoising scheme, each component in RGB is usually denoised separately, without considering the correlation characteristics of each component, resulting in high complexity of the denoising process, and due to the R, G The difference in the denoising strength of the three components of B and B may result in poor display effect of the denoised image. Contents of the invention [0003] Embodiments of the present application provide an image denoising method, device, and storage medium to solve the problems in the prior art that the denoising process is highly complex and the denoising image display effect is poor. [0004] The first aspect of the embodiments of the present application provides an image denoising method, the method co...
