Abstract

The invention provides an image denoising method, an image denoising device, a storage medium and electronic equipment, and relates to the technical field of image processing. The image denoising method comprises the steps of partitioning a to-be-processed image to obtain a plurality of image blocks; respectively determining a plurality of matching blocks corresponding to the current image block in a plurality of reference frames through multi-frame motion estimation; and performing weighted fusion on the plurality of matching blocks and the current image block to perform denoising operation on the current image block to obtain a target image corresponding to the to-be-processed image. According to the embodiment of the invention, the image denoising effect can be improved, and the image quality is further improved.

Description

technical field [0001] The present disclosure relates to the technical field of image processing, and in particular, to an image denoising method, an image denoising device, a computer-readable storage medium, and electronic equipment. Background technique [0002] As the requirements for image display become higher and higher, in the process of image processing, image denoising operations can be performed to improve image quality. [0003] In the multi-frame denoising algorithm of the related art, methods such as non-local mean are mostly used, and for each image block of the image in the spatial or temporal domain, multiple matching blocks are searched for matching according to the similarity between the image blocks to perform fusion filtering , in order to achieve the purpose of denoising. Wherein, because only the similarity of the image blocks is considered, the number of matching blocks obtained through matching is too large, which increases the computational complex...
