# simple-mask-utils

Utility functions around image segmentation masks and turning them into polygons.

## Installation

You can install the library via `pip` (or `pip3`):

```bash

pip install simple-mask-utils

```

Or directly from the repo:

```bash

pip install https://github.com/waikato-datamining/simple-mask-utils.git

```

## Usage

```python

from smu import mask_to_polygon, polygon_to_lists

mask = ...  # binary mask (0/1) or float mask (0-1)

polys = mask_to_polygon(mask)  # determine polygons

for poly in polys:

    px, py = polygon_to_lists(poly, swap_x_y=True, as_type="int")  # get coordinates

```
