| Abstract: | Based on analysis to the principles and indexes of similarity measure by set theory and set operation, the similarity measure to spectral vectors in hyperspectral RS image was transformed into the similarity measure to corresponding sets. Two approaches used to spectral similarity measure based on set theory were proposed, one is similarity measure by the area of spectral polygon, and the other is by locations of characterized bands. It proved that the approach based on spectral polygon can be used to similarity measure and image retrieval effectively because of its synthetic applications to albedo and wavelength information. |
