## A hand-constructed image from Besag (1986)

### Description

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.

### Usage

```
data(besag)
```

### Format

an `100 \times 88`

matrix with entries `1`

and `2`

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 `0-1`

binary
dataset, either use `besag - 1`

or `besag %% 2`

.
