Abstract :
Classification of AVIRIS data is considered with respect to enhanced statistics. The performance of enhanced statistics is investigated in terms of feature extraction for both pixel and spatial classifiers. The feature extraction methods applied are decision boundary feature extraction and discriminant analysis. The classification results obtained by enhanced statistics are excellent and show the classifiers to be able to distinguish between several geological units with very similar spectral properties
