Title:
IMAGE DENOISING METHOD AND SYSTEM, AND STORAGE MEDIUM
Document Type and Number:
WIPO Patent Application WO/2023/115792
Kind Code:
A1
Abstract:
The present application relates to the technical field of image processing, and discloses an image denoising method and system, and a storage medium. The method comprises: performing, by means of empirical mode decomposition, fuzzy processing on an image to be processed to obtain a blurred feature image; performing edge detection processing on the feature image to obtain an edge detection operator of the feature image; calculating a diffusion threshold of a preset anisotropic diffusion equation according to the edge detection operator, and determining an improved anisotropic diffusion equation according to the calculated diffusion threshold; and performing, by means of the improved anisotropic diffusion equation, diffusion processing on the image to be processed to obtain denoised image information. By using the method, the influence of image noise on an edge detection result can be weakened, and the image denoising effect can be improved.
