Prune the branches of a region.
::pruning removes branches from a skeleton (Region) having a length less than Length. All other branches are preserved.
|
Region (input_object) |
region(-array) -> Hobject: HRegion(Array) |
| Regions to be processed. | |
|
RegionPrune (output_object) |
region(-array) -> Hobject * : HRegion(Array) |
| Result of the pruning operation. | |
|
Length (input_control) |
integer -> HTuple.long |
| Length of the branches to be removed. | |
| Default value: 2 | |
| Suggested values: 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 12, 15, 17, 20, 30, 40, 50 | |
| Typical range of values: 1 <= Length <= 511 (lin) | |
| Minimum increment: 1 | |
|
Recommended increment: 1 | |
Let F be the area of the input region. Then the runtime complexity for one region is
O(Length * 3 * sqrt(F)) .
::pruning returns H_MSG_TRUE if all parameters are correct. The behavior in case of empty or no input region can be set via:
a) no region: set_system('no_object_result',<RegionResult>)
b) empty region: set_system('empty_region_result',<RegionResult>)
Otherwise, an exception is raised.
