摘要

将谱加权结构张量(SWST)应用于张量非线性各向异性扩散(TAND)中进行相干增强扩散(CED)。介绍了甲状腺组织高光谱图像的空间增强实验。将基于SWST的扩散张量的TAND-CED与基于CST的扩散张量的TAND-CED进行了比较。两种方法的比较表明,采用CED的SWST方法可以得到更完整的边缘。

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.
