# img-fut

An image library in [Futhark](https://futhark-lang.org/) providing

multidimensional image processing à la

[scipy](https://docs.scipy.org/doc/scipy/reference/ndimage.html).

Documentation is [here](https://vmchale.github.io/img-fut/).

## Performance

When using the GPU, `img-fut` outperforms

[SciPy](https://scipy.org/) on large images and performs similarly for small

images.
