Abstract :
New methods for processing of multisource and hyperdimensional data are discussed both in terms of feature extraction and classification. An extension to decision boundary feature extraction (DBFE) is proposed. The extension is based on a recently developed covariance estimator, the leave one out covariance (LOOC). The extended decision boundary method is tested on a multisource remote sensing and geographic data set
