besag

<p>An \(100 \times 88\) matrix representing a two-color
hand-drawn scene designed specifically to contain some
awkward features for an image reconstruction method
evaluated in the paper.</p>

datasets

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) <doi:10.48550/arXiv.2004.09073>.

Binary and Categorical Image Similarity Index

besag function

<p>an \(100 \times 88\) matrix with entries <code>1</code> and <code>2</code>
denoting the color of the corresponding pixels. The example code will
produce the image as it is in the original paper. To use as a <code>0-1</code> binary
dataset, either use <code>besag - 1</code> or <code>besag %% 2</code>.</p>
