Zusammenfassung: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. 在利用已知的关于有噪图像的图像分辨率上调方法的情况下，在去噪期间丢失重要的细节信息。种用于对有噪输入图像进行分辨率上调的方法(100)包括：对有噪输入图像进行分辨率上调以获得有噪高分辨率(HR)图像，对有噪输入图像进行去噪(30)以获得去噪低分辨率(LR)图像，对去噪LR图像进行分辨率上调(40)以获得经分辨率上调的去噪LR图像，以及将有噪HR图像与经分辨率上调的去噪LR图像进行组合(50)以生成去噪HR图像。
