Abstract
Local binary patterns (LBPs) have been extensively used to yield spatial features for the classification of general imagery, and a few recent works have applied these patterns to the classification of hyperspectral imagery. Although the conventional LBP formulation employs only the signs of differences between a central pixel and its surrounding neighbors, it has been recently demonstrated that the difference magnitudes also possess discriminative information. Consequently, a sign-and-magnitude LBP is proposed to provide a spatial–spectral class-conditional probability for a Bayesian maximum a posteriori formulation of hyperspectral classification wherein the prior probability is provided by a Markov random field. Experimental results demonstrate that the performance of the proposed approach is superior to that of other state-of-the-art algorithms, tending to result in smoother classification maps with fewer erroneous outliers even in the presence of noise.
