Abstract
Description
technical field
[0001] The invention belongs to the technical field of computer vision, in particular to an image denoising method. Background technique
[0002] Images are an important source of information for people to obtain. However, due to various reasons when acquiring images, noise will be mixed into the image, which will lead to the degradation of image quality, which will bring great trouble to the subsequent processing of the image. Image processing such as "edge detection", "image segmentation", "feature extraction" and "pattern recognition" has a serious impact. Therefore, image denoising is a very important part of image processing and the basis of subsequent image processing.
[0003] At present, there are many algorithms for image denoising, which are mainly divided into two categories: one is the traditional image denoising algorithm, and the more typical algorithm is Gaussian filtering. However, using this method for image denoising will cause blurring of...
