Abstract:

With the wide application of hyperspectral images in various fields, the theory of sparse representation of signals has been getting more attention from researchers. This paper presents a classified redundant dictionary-learning algorithm of hyperspectral image based on geologic feature. Experimental results showed that hyperspectral image signals could be expressed with the greatest fidelity. The algorithm constructs redundant dictionary library through a sparse decomposed image according to the geologic feature based on clustering, which more accurately represents the spectral signal in sparse reconstruction. To apply the classification dictionary library to super-resolution restoration of hyperspectral image, sparse decomposed hyperspectral image is needed to obtain high and low resolutions of a redundant dictionary. Then, low resolution and dictionary of hyperspectral image restoration could be obtained. The algorithm could effectively improve image resolution to ensure the quality of image restoration.
