Abstract

The embodiment of the invention discloses a computer device for removing multiplicative noise of a color image and equipment. The computer device comprises a noise removal assembly used for carrying out multiplicative noise removal on an input color image to be processed, and the noise removal assembly comprises an image collector used for obtaining the color image to be processed and a model construction module used for constructing a denoising model in advance and determining various parameters of the denoising model. The model construction module comprises a similarity processing sub-moduleused for determining the similarity between the to-be-processed color image and the denoised color image based on data items of a universal multiplicative noise model, and a smoothing processing sub-module used for determining the smoothness of the denoised color image based on rule items of a coupling MTV model and a high-order TC model; and the data processing sub-module is used for calculatingvarious parameters of the denoising model by utilizing an augmented Lagrange method and an alternate optimization multiplier method. The non-edge area of the denoised image is smooth and natural, thestep effect is eliminated, and the edge and corner points of the color image are well kept.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of image processing, in particular to a computer device and equipment for removing multiplicative noise in color images. Background technique [0002] With the rapid development of computer vision technology, its application in all walks of life and daily life is becoming more and more extensive. Image processing is a key part of computer vision technology. very important in the implementation process. [0003] It is understandable that the image will generate noise during the transmission or storage process, and the noise has a great impact on the image quality. Effectively removing the noise in the image is conducive to obtaining a high-quality image, increasing the signal-to-noise ratio, and better reflecting the original image. information carried. According to the relationship between noise and signal, image noise can be divided into additive noise and multiplicative noise. The ...
