Abstract

The invention discloses an unsupervised remote sensing image super-resolution reconstruction method based on image recursion. Obtaining an original low-resolution image; extracting a degradation kernel from the original low-resolution image; performing down-sampling on the original low-resolution image by using a degradation kernel to obtain a low-resolution image after down-sampling; training the super-resolution reconstruction network model based on the original low-resolution image and the down-sampled low-resolution image; and adopting the super-resolution reconstruction network model to test the to-be-tested low-resolution image to obtain a corresponding super-resolution reconstruction result. Through the method, a super-resolution reconstruction method can be applied to the remote sensing image, so that the accuracy of obtaining pairing data from the remote sensing image is improved, and a network realizes a good reconstruction effect on downsampling used for reconstruction synthesis.

Description

technical field [0001] The invention belongs to the technical field of digital image processing, in particular to an unsupervised remote sensing image super-resolution reconstruction method based on image recursion. Background technique [0002] Super-resolution reconstruction is a method of reconstructing low-resolution images with less details into high-resolution images with rich texture details. Single-frame image super-resolution reconstruction means that the input image data is non-sequential images, and the single-frame image Image processing tasks that process low-resolution image data into high-resolution images with rich texture details and better visual effects. At present, the super-resolution reconstruction of remote sensing images mostly adopts deep learning methods, and the supervised image super-resolution reconstruction methods based on deep learning are all trained by image pairs of low-resolution images and high-resolution images of the same area. It is v...
