%description
Computes a structural similarity metric (after the style of MS-SSIM for
images) for binary and categorical 2D and 3D images. Can be based on
accuracy (simple matching), Cohen's kappa, Rand index, adjusted Rand
index, Jaccard index, Dice index, normalized mutual information, or
adjusted mutual information. In addition, has fast computation of Cohen's
kappa, the Rand indices, and the two mutual informations. Implements the
methods of Thompson and Maitra (2020) <arXiv:2004.09073>.
