-### Segmenting
+### Using a CNN to segment an image
+To lower the memory consumption and inference time for segmenting the airways, we can first segment the lobes and use this as a bounding box for cropping the image
+```bash
+python segment_lunglobes.py -i /path/to/ct/scan.mhd -id example
+```
+The airways can then be segmented by 
+```bash
+python segment.py -i /path/to/ct/scan.mhd -o example.stl
+```
+which will create three files in the current directory (`example.mhd`, `example.zraw` and `example.stl`).
