Abstract

This paper develops a novel approach that embeds minimum noise fraction (or noise-adjusted principal component analysis) in canonical analysis (called noise-adjusted canonical analysis, NACA). The objective is to take the discriminability of targets and quality of image into account simultaneously when extracting features from hyperspectral image data sets. Experimental results indicate that the NACA algorithm for classification task can produce better results than principal component analysis, conventional canonical analysis and minimum noise fraction from an airborne and an EO-1 Hyperion image data.
