- Abstract
A novel classification approach for hyperspectral data based on sparse representation framework is proposed in this paper. This new method divides all spectrums of hyperspectral samples to sub-dictionaries based on spectral characteristics of the data themselves. Meanwhile, a weighting algorithm based on minimum residual is adopted to combine sub-dictionaries. Experimental results show that our proposal obtained higher accuracy comparing with that of a whole dictionary.
