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 (100) for upscaling noisy input images comprises upscaling (20) a noisy input image to obtain a noisy High-Resolution (HR) image, denoising (30) the noisy input image to obtained a denoised Low-Resolution (LR) image, upscaling (40) the denoised LR image to obtain an upscaled denoised LR image, and combining (50) the noisy HR image and the upscaled denoised LR image to generate a denoised HR image.
