### Basic Shepherd Segmentation with pyshepseg

Source: https://www.pyshepseg.org

Shows how to import pyshepseg and call doShepherdSegmentation on a multi-band image array. Requires a null value for null pixels; incorrect null handling can degrade segmentation quality.

```python
from pyshepseg import shepseg

# Read in a multi-band image as a single array, img,
# of shape (nBands, nRows, nCols).
# Ensure that any null pixels are all set to a known
# null value in all bands. Failure to correctly identify
# null pixels can result in a poorer quality segmentation.

segRes = shepseg.doShepherdSegmentation(img, imgNullVal=nullVal)

```
