Method for upscaling noisy images, and apparatus for upscaling noisy images

摘要

With known image upscaling methods of noisy images, important detail information is lost during denoising. A method for upscaling noisy input images comprises upscaling a noisy input image to obtain a noisy High-Resolution (HR) image, denoising the noisy input image to obtained a denoised Low-Resolution (LR) image, upscaling the denoised LR image to obtain an upscaled denoised LR image, and combining the noisy HR image and the upscaled denoised LR image to generate a denoised HR image.
