| -invert | Invert density in the image before other operations. |
| -list | List regions or regions (use with -threshold). |
| -color | Generate a color image based on region size. |
| -series 1.3,4.7,0.05 | Segment through a series of thresholds: start,finish,increment. |
| -peaks 12,1.4,1,1 | Find peaks within a kernel size, above a threshold, |
