Description
Summary:In this paper, we consider the problem of Blind source separation (BSS) method by taking advantage of the sparse modeling of the hyperspectral images. These images are produced by sensors which provide hundreds of narrow and adjacent spectral bands. The idea behind transform domains is to apply some transformations to illustrate the dataset with a minimum of components and a maximum of essential information. To take advantages from the new representation of hyperspectral data, a novel classification approach based on using Binary Partition Trees (BPT). The BPT is obtained by iteratively merging regions and provided a combined and hierarchical representation of the image in a tree structure of regions.
