minkowski_sub2minkowski_sub2MinkowskiSub2minkowski_sub2MinkowskiSub2MinkowskiSub2 computes the Minkowski subtraction of the
input regions with a structuring element (StructElementStructElementStructElementStructElementStructElementstructElement)
having the reference point (RowRowRowRowRowrow,ColumnColumnColumnColumnColumncolumn).
minkowski_sub2minkowski_sub2MinkowskiSub2minkowski_sub2MinkowskiSub2MinkowskiSub2 has a similar effect as
minkowski_sub1minkowski_sub1MinkowskiSub1minkowski_sub1MinkowskiSub1MinkowskiSub1, the difference is that the reference
point of the structuring element can be chosen arbitrarily. The
parameter IterationsIterationsIterationsIterationsIterationsiterations determines the number of iterations
which are to be performed with the structuring element. The result
of iteration n-1 is used as input for iteration n.
A maximum region is generated in case of an empty structuring
element.
Structuring elements (StructElementStructElementStructElementStructElementStructElementstructElement) can be generated
with operators such as gen_circlegen_circleGenCirclegen_circleGenCircleGenCircle, gen_rectangle1gen_rectangle1GenRectangle1gen_rectangle1GenRectangle1GenRectangle1,
gen_rectangle2gen_rectangle2GenRectangle2gen_rectangle2GenRectangle2GenRectangle2, gen_ellipsegen_ellipseGenEllipsegen_ellipseGenEllipseGenEllipse,

- Multithreading type: reentrant (runs in parallel with non-exclusive operators).
- Multithreading scope: global (may be called from any thread).
- Automatically parallelized on tuple level.

Let F1 be the area of the input region, and F2 be the area of
the structuring element. Then the runtime complexity for one region
is:
minkowski_sub2minkowski_sub2MinkowskiSub2minkowski_sub2MinkowskiSub2MinkowskiSub2 returns 2 (H_MSG_TRUE) if all parameters are
correct. The behavior in case of empty or no input region can be
set via:
-
no region:
set_system('no_object_result',<RegionResult>)
-
empty region:
set_system('empty_region_result',<RegionResult>)
Otherwise, an exception is raised.
