Discriminative dictionary learning aims to learn a dictionary from training samples in order to improve the discriminative ability of their coding vectors. Gabor wavelets have recently been successfully applied for hyperspectral image (HSI) classification due to their ability to extract joint spatial and spectrum information. Due to the high discriminative power of Gabor features, an efficient method,...
In this paper, a three-dimensional (3D) Gabor phase coding and Hamming distance matching approach, called 3DGPC-HDM, is proposed for hyperspectral imagery classification. Specifically, the Gabor phase features with certain orientations are utilized, which are then encoded by a simple quadrant bit coding scheme. Next, a normalized Hamming distance matching method has been introduced to determine the...
