Abstract

The embodiment of the present invention discloses a method and device for rapid denoising of an image, wherein the method for rapid denoising of an image includes: dividing the image into regions according to the brightness values ​​of pixels in the image; Region, use the denoising intensity corresponding to the current region to denoise the current region. Using the technical solution provided by the embodiment of the present invention, a smaller denoising intensity is used for areas with higher brightness to ensure that the image details in areas with higher brightness are not lost, and a larger denoising intensity can be used for areas with lower brightness , can effectively control the noise, maintain the integrity of the original information in the low brightness area, can effectively improve the image quality, increase the signal-to-noise ratio, and better reflect the information carried by the original image.

Description

technical field [0001] Embodiments of the present invention relate to the field of image processing, and in particular, to a method and device for fast image denoising. Background technique [0002] With the popularization of digital products, images and videos have become the most commonly used information carriers in human activities. They contain a lot of information about objects and become the main way for people to obtain original information from the outside world. However, in the process of image acquisition, transmission and storage, it is often interfered and affected by various noises, which degrades the image quality. In order to obtain high-quality digital images, it is necessary to denoise the images to remove useless information in the signal while maintaining the integrity of the original information (that is, the main features) as much as possible. [0003] The currently used denoising algorithms all select different denoising strengths according to the amb...
