| Options | Output | Choice | OUTPUT | The values of the resultant grid can be either the seed value (e.g. the local maximum) or the enumerated segment id. | Available Choices: [0] Seed Value [1] Segment ID Default: 1 |
| Method | Choice | DOWN | Choose if you want to segmentate either on minima or on maxima. | Available Choices: [0] Minima [1] Maxima Default: 1 | |
| Join Segments based on Threshold Value | Choice | JOIN | Join segments based on threshold value. | Available Choices: [0] do not join [1] seed to saddle difference [2] seeds difference Default: 0 | |
| Threshold | Floating point | THRESHOLD | Specify a threshold value as minimum difference between neighboured segments. | Minimum: 0.000000 Default: 0.000000 | |
| Allow Edge Pixels to be Seeds | Boolean | EDGE | - | Default: 1 | |
