Compute the skeleton of a region.
skeleton computes the skeleton of the input regions.
Region (input_object) |
region(-array) -> object |
Region to be thinned. |
Skeleton (output_object) |
region(-array) -> object |
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 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 is raised.
