- W2016239178 abstract "In this letter, we present a novel approach for spectral-spatial classification in hyperspectral imagery. To this end, after applying principal component analysis (PCA) for dimensionality reduction, we extract the spectral-spatial information by first reorganizing the local image patch with the first d principal components(PCs) into a vector representation, followed by a sorting scheme to make it invariant to local image rotation.. Since no additional operation except sorting the pixels is required, this step is performed efficiently. Afterwards, the resulting feature descriptors are embedded into a linear support vector machine (SVM) for classification. To evaluate the proposed method, experiments were preformed on two hyperspectral images with high spatial resolution. The experimental results confirmed that the proposed method outperforms the existing algorithms on classification accuracy." @default.
