- W2377144496 abstract "Spectral unmixing is an important and challenging task in the field of hyperspectral data analysis. The existing methods of blind unmixing have certain limitations. In this paper,we present a new blind unmixing method,namely the ATGP-NMF algorithm,for hyperspectral imagery. The method is based on the improved target endmember acquired through integration of the Automatic Target Generation Process( ATGP) algorithm and the Non-negative Matrix Factorization( NMF). The Harsanyi-FarrandChang( HFC) algorithm was introduced firstly to determine the number of target endmembers. Then the ATGP algorithm and NonNegative Least Squares( NNLS) were used to obtain the spectra and abundances of the target endmembers,which were then used as initial values for the NMF algorithm to obtain the refined endmembers. Finally,an improved cross correlogram spectral matching method was introduced to match the corresponding land cover type of each endmember. Three different sets of data,namely simulated data,laboratory-controlled spectral experimental data and remote sensing imagery,were used in this study to test the effectiveness and robustness of the proposed method,in comparison with the original NMF algorithm. Results from these experiments show that the ATGP-NMF algorithm can obtain endmembers with high accuracy and it is more robust and efficient than the original NMF algorithm in different situations,regardless of the existence of pure pixels,inter-class diversity,or correlation among the endmembers' spectra. The ATGP-NMF algorithm thus has great potential of application in blind unmixing for hyperspectral imagery." @default.
