Abstract: An image denoising method and system, and storage medium are disclosed, which relate to the technical field of image processing. The method including: performing blur processing on an image to be processed by means of empirical mode decomposition 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 using the improved anisotropic diffusion equation, diffusion processing on the image to be processed to obtain denoised image information. With the above method, the impact of the image noise on edge detection results can be weakened and the image denoising effect can be improved.
