Abstract

The present work presents a new program for spectral classification of hyperspectral images based on the positioning of the absorption band. The program generates an image where the value of the pixel is the wavelength of the absorption band after of the continuum removal. That program when used in he presence of similar spectral features it provides a classification with better results than the usual procedures (SAM, SCM, SFF, correlation coefficient R used by Tricorder). That program was tested in hyperspectral image AVIRIS obtaining excellent resulted so much in the mineralogical discrimination as of the vegetation
