摘要

This letter presents a correntropy-based sparse spectral clustering (CSSC) method to select proper bands of a hyperspectral image. The CSSC first constructs an affinity matrix with the correntropy measure which considers the nonlinear characteristics of hyperspectral bands and can suppress effects from noise or outliers in measuring band similarity. The CSSC imposes the sparsity and block diagonal constraint on spectral clustering, which can further improve band clustering performance. Bands are finally selected from each cluster on the connected graph. Experimental results on two widely used hyperspectral images show that the CSSC behaves better than spectral clustering and other several state-of-the-art methods in band selection.
