Problems solved by technology

Due to the larger observation range of remote sensing images, richer texture information, and richer landform features of different types of objects, in order to achieve a certain reconstruction effect, the size of the dictionary will be increased to ensure the number of effective atoms, resulting in excessive reconstruction speed. slow

Abstract

The invention provides a remote sensing image super resolution method based on dictionary learning, comprising the following steps: S1, performing dictionary learning of corresponding feature types based on an image library of different feature types; S2, identifying the feature type of an original image; and S3, carrying out an image super resolution reconstruction process using a corresponding feature type dictionary. The invention puts forward a super resolution method based on dictionary learning using the idea of feature classification. As the number of atoms in a dictionary used in the reconstruction process is reduced greatly, the dictionary scale is reduced greatly. The proportion of effective atoms in the classification dictionary used is increased significantly, so that the number of effective atoms in the dictionary used in the reconstruction process is almost the same as a general dictionary, and the speed of reconstruction is improved significantly while the quality of reconstruction is ensured. The process only involves the adjustment of parameters, the computation efficiency is high, and the reconstruction quality of remote sensing images is high.

Description

technical field [0001] The invention relates to the technical field of remote sensing imaging, in particular to a method for super-resolution of remote sensing images based on dictionary learning. Background technique [0002] With the development of computer science and space science, remote sensing technology, especially remote sensing imaging, has developed rapidly. Image spatial resolution is a key index for evaluating the quality of remote sensing images, and also an important parameter in the application of remote sensing imaging, which is crucial in the acquisition and application of images. Compared with traditional low-resolution remote sensing images, high-resolution remote sensing images can clearly express the characteristic distribution and spatial correlation of ground objects, and can distinguish the more detailed structural composition of ground objects, providing a basis for interpretation and analysis. Excellent condition and foundation. In recent years, ...
