Abstract

The invention provides an image denoising method and device, electronic equipment and a storage medium, and relates to the technical field of image processing, and the method comprises the steps: determining a first sampling point and a first weight in a first direction; according to the current pixel value of the to-be-processed pixel point, the pixel value of the first sampling point and the first weight, performing first filtering processing in a first direction to obtain a first pixel value of the to-be-processed pixel point; and determining a second sampling point and a second weight in a second direction, and performing second filtering processing in the second direction according to the first pixel value of the to-be-processed pixel point, the pixel value of the second sampling point and the second weight to obtain a second pixel value of the to-be-processed pixel point as a current pixel value of the to-be-processed pixel point. According to the invention, the image denoising efficiency is improved, the operation complexity is reduced, the image denoising capability is improved, and the image quality of ISP processing can be improved.

Description

technical field [0001] The present disclosure relates to the technical field of image processing, and in particular, to an image denoising method, device, electronic equipment, and storage medium. Background technique [0002] At present, in order to enable customers to obtain a real perceptual experience of the house, a "VR viewing" has been launched, which uses VR technology to truly restore the three-dimensional scene of the house. Users can roam and visit from multiple angles through keyboard and mouse control. Indoor and other scene data can be obtained through panoramic cameras, depth cameras, lidar and other equipment to construct a 3D scene of the listing. "VR viewing" needs to integrate and apply multiple technologies. The house photos presented to customers need to be processed by ISP (Image Signal Process, Image Signal Processing). During the ISP processing, the image needs to be denoised. Since the final photos presented to customers during the VR viewing will a...
