Title: IMAGE DENOISING METHOD AND DEVICE, AND COMPUTER STORAGE MEDIUM
Abstract:
Disclosed are an image denoising method and device. The method may comprise: traversing pixel points of an image to be processed according to a preset direction template set, to obtain a current direction and current direction reliability for each pixel point; performing DWF filtering according to the current direction of each pixel point and a preset direction-based weighted filtering DWF template, to obtain a DWF filtering result for each pixel point; performing filtering on the pixel points of the image to be processed according to a preset bilateral filtering (BF) template, to obtain a BF filtering result for each pixel point; and performing mixed output according to the DWF filtering result and BF filtering result of each pixel point and based on the respective current direction reliability, to obtain a denoised image. Also disclosed is a computer storage medium.
