Abstract

For hyperspectral remote sensing imagery, the observation of image pixel usually consists of more than one material, causing it to be a “mixed pixel”. In order to analyze the hyperspectral dataset, it is necessary to decompose the mixed pixels into a collection of substances’ spectra and their corresponding abundance proportions. However, hyperspectral dataset usually contains hundreds of spectral images, which brings rather large computational complexity. This paper presents a quick approach to estimate the abundances by exploiting matrix triangular factorization, which can rectify possible bias in the given spectral by utilizing the data’s geometric spatial information. This property is rather effective especially when no pure-pixel presents in the imagery. Experimental results on real hyperspectral data indicate that the proposed approach can obtain desirable results
