| Zusammenfassung: | 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).
잡음 있는 이미지들의 공지된 이미지 업스케일링 방법들을 이용하면, 잡음제거 동안 중요한 상세 정보가 유실된다. 잡음 있는 입력 이미지들을 업스케일링하기 위한 방법(100)은 잡음 있는 입력 이미지를 업스케일링하여(20) 잡음 있는 고해상도(HR) 이미지를 획득하는 단계, 잡음 있는 입력 이미지를 잡음제거하여(30) 잡음제거된 저해상도(LR) 이미지를 획득하는 단계, 잡음제거된 LR 이미지를 업스케일링하여(40) 업스케일링된 잡음제거된 LR 이미지를 획득하는 단계, 및 잡음 있는 HR 이미지와 업스케일링된 잡음제거된 LR 이미지를 결합시켜(50) 잡음제거된 HR 이미지를 생성하는 단계를 포함한다. |
