Title:
DEHAZING USING LOCALIZED AUTO WHITE BALANCE
Document Type and Number:
WIPO Patent Application WO/2021/184028
Kind Code:
A8
Abstract:
This application is directed to dehazing an image using localized white balance adjustment. A computer system obtains an input image and detects one or more hazy zones in the input image. A predefined portion of pixels having minimum pixel values are identified in each of the one or more hazy zones. The input image is modified to a first image by locally saturating the predefined portion of pixels in each of the one or more hazy zones to a low-end pixel value limit. The computer system further blends the input image and the first image to form a target image.
