Coherence enhancement diffusion for hyperspectral imagery using a spectrally weighted structure tensor
A spectrally weighted structure tensor (SWST) is applied to tensor nonlinear anisotropic diffusion (TAND) for Coherence Enhancing Diffusion (CED). Experiments on spatial enhancement of hyperspectral imagery from thyroid tissue are shown. TAND-CED with a diffusion tensor derived from the SWST is compared with the one using the diffusion tensor derived from the classical (uniformly weighted) structure tensor (CST). Comparisons between methods show that the SWST produces more complete edges with CED.
