This chapter introduces several feature selection and pattern recognition methods that are often used in hyperspectral imagery. Distance metrics and feature search strategies are two main aspects in the feature selection. The goal of linear projection-based feature selection methods is to transform the image data from original space into another space of a lower dimension. A second-order statistics-based classification method needs the assumption of a probability density model of the data, and such an assumption itself is a challenging problem. Neural networks are nonlinear statistical data modeling tools, which can be used to model complex relationships between inputs and outputs in order to find patterns in the image data. The kernel method appears to be especially advantageous in the analysis of hyperspectral data. For example, support vector machine implements a maximum margin-based geological classification strategy, which shows the robustness of high dimensionality of the hyperspectral data and low sensitivity of the number of training data.
