Description

technical field [0001] The present invention relates to the technical field of image processing, in particular to a super-resolution image reconstruction method and system based on a recursive very deep network. Background technique [0002] Image super resolution (super resolution, SR for short) refers to the process of restoring high resolution (high resolution, HR for short) images from low resolution (low resolution, LR for short) images, which is an important technology in computer vision and image processing. Means, with a wide range of practical applications, such as medical imaging, security monitoring and remote sensing images and other fields. In addition to improving the perceived quality of images, it can also help improve other computer vision tasks. Since the image super-resolution is very challenging, it is an ill-posed inverse problem since there are cases where multiple HR images correspond to a single LR image. [0003] The image super-resolution methods ...
