get_region_thicknessT_get_region_thicknessGetRegionThicknessGetRegionThicknessget_region_thickness (Operator)
Name
get_region_thicknessT_get_region_thicknessGetRegionThicknessGetRegionThicknessget_region_thickness — Access the thickness of a region along the main axis.
Signature
def get_region_thickness(region: HObject) -> Tuple[Sequence[int], Sequence[int]]
Description
The operator get_region_thicknessget_region_thicknessGetRegionThicknessGetRegionThicknessGetRegionThicknessget_region_thickness calculates the thickness of the
regions along the main axis (see elliptic_axiselliptic_axisEllipticAxisEllipticAxisEllipticAxiselliptic_axis)
for each pixel of the section. The thickness at one point on the main axis
is defined as the distance between the intersections of the contour with
the plumb on the main axis in the respective point which are the furthest
apart.
Additionally the operator get_region_thicknessget_region_thicknessGetRegionThicknessGetRegionThicknessGetRegionThicknessget_region_thickness returns the
HistogrammHistogrammHistogrammHistogrammhistogrammhistogramm
of the thicknesses of the region.
The length of the histogram corresponds to the largest
occurring thickness in the observed region.
Attention
Only one region may be passed. If the region has several connection
components, only the first one is investigated. All other components
are ignored.
Execution Information
- Multithreading type: reentrant (runs in parallel with non-exclusive operators).
- Multithreading scope: global (may be called from any thread).
- Processed without parallelization.
Parameters
RegionRegionRegionRegionregionregion (input_object) region → objectHRegionHObjectHRegionHobject
Region to be analyzed.
ThicknessThicknessThicknessThicknessthicknessthickness (output_control) integer-array → HTupleSequence[int]HTupleHtuple (integer) (int / long) (Hlong) (Hlong)
Thickness of the region along its main axis.
HistogrammHistogrammHistogrammHistogrammhistogrammhistogramm (output_control) integer-array → HTupleSequence[int]HTupleHtuple (integer) (int / long) (Hlong) (Hlong)
Histogram of the thickness of the region along
its main axis.
Result
The operator get_region_thicknessget_region_thicknessGetRegionThicknessGetRegionThicknessGetRegionThicknessget_region_thickness returns the value 2 (H_MSG_TRUE)
if exactly one region is passed.
The behavior in case of empty input (no input regions available) is set via
the operator set_system('no_object_result',<Result>)set_system("no_object_result",<Result>)SetSystem("no_object_result",<Result>)SetSystem("no_object_result",<Result>)SetSystem("no_object_result",<Result>)set_system("no_object_result",<Result>).
