Parameters

	Name	Type	Identifier	Description	Constraints
Input	Grid	Grid (input)	`GRID`	-	-
Output	Segments	Grid (output)	`SEGMENTS`	-	-
	Seed Points	Shapes (output)	`SEEDS`	-	-
	Borders (*)	Data Object (optional output)	`BORDERS`	-	-
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
	Borders	Boolean	`BBORDERS`	Create borders between segments as new grid.	Default: 0
(*) optional
