Compute the skeleton of a region.
::skeleton computes the skeleton of the input regions.
|
Region (input_object) |
region(-array) -> Hobject: HRegion(Array) |
| Region to be thinned. | |
|
Skeleton (output_object) |
region(-array) -> Hobject * : HRegion(Array) |
| Resulting skeleton. | |
| Number of elements: Skeleton == Region | |
Let F be the area of the enclosing rectangle of the input region. Then the runtime complexity is O(F) (per region).
::skeleton returns H_MSG_TRUE if all parameters are correct. The behavior in case of empty input (no regions given) can be set via ::set_system('no_object_result',<Result>) and the behavior in case of an empty input region via ::set_system('empty_region_result',<Result>). If necessary, an exception handling is raised.
