feature extraction (FE)

A New Spatial?Spectral Feature Extraction Method for Hyperspectral Images Using Local Covariance Matrix Representation Abstract-In this paper, a novel local covariance matrix (CM) representation method is proposed to fully characterize the correlation among different spectral bands and the spatial?contextual information in the scene when conducting feature extraction (FE) from hyperspectral images (HSIs). Specifically, our method…
