METHOD FOR UPSCALING NOISY IMAGES AND DEVICE FOR UPSCALING NOISY IMAGES

摘要

When conventional image upscaling methods are used in noisy images, important detailed information is deleted during noise removal. A noisy input image upscaling method (100) according to the present invention comprises: a step of obtaining a noisy high-resolution (HR) image by upscaling a noisy input image (20); a step of obtaining a noise deleted low-resolution (LR) image by deleting noise from the noisy input image (30); a step of obtaining the upscaling and noise deleted LR image by upscaling the noise deleted LR image (40); and a step of generating a noise deleted HR image by combining the noisy HR image with the upscaling and the noise deleted LR image (50).
