Abstract

The embodiment of the invention provides an image denoising method and device, electronic equipment and a readable storage medium. The method comprises the steps: determining brightness information ofeach target pixel in a to-be-processed pixel neighborhood matrix currently extracted from a target image; according to the brightness information of each target pixel, calculating a variance of the brightness information of the target pixel in each preset direction by taking the to-be-processed pixel as a center; judging whether the to-be-processed pixel has directivity or not according to the variance; if yes, calculating the final denoising weight of each target pixel in combination with the intensity of the directivity of the to-be-processed pixel; otherwise, directly calculating the denoising weight of each target pixel; and finally, denoising the to-be-processed pixel according to the denoising weight of each target pixel. According to the embodiment of the invention, the calculationcomplexity of image denoising processing based on the pixel point direction can be effectively reduced, and the denoising effect of the image can be effectively improved.

Description

technical field [0001] The embodiments of the present application relate to the technical field of image processing, and in particular, to an image denoising method, device, electronic equipment, and readable storage medium. Background technique [0002] At present, image sensors of mobile terminals usually use complementary metal oxide semiconductor (Complementary Metal Oxide Semiconductor, CMOS for short) chips. It usually contains noise, so it is necessary to use a related noise removal method to denoise the acquired image data. Among them, in the process of denoising image data, it is generally necessary to set different denoising strengths for different regions in combination with related factors such as brightness, detail, and direction. Combining the image edge direction to denoise the image can achieve smooth and more continuous image edges while ensuring noise removal, which is of great help to improve the denoising effect. [0003] In the prior art, when denoisin...
