minkowski_add2minkowski_add2MinkowskiAdd2minkowski_add2MinkowskiAdd2MinkowskiAdd2 computes the Minkowski addition of the
input regions with a structuring element (StructElementStructElementStructElementStructElementStructElementstructElement)
having the reference point (RowRowRowRowRowrow,ColumnColumnColumnColumnColumncolumn).
minkowski_add2minkowski_add2MinkowskiAdd2minkowski_add2MinkowskiAdd2MinkowskiAdd2 has a similar effect as
minkowski_add1minkowski_add1MinkowskiAdd1minkowski_add1MinkowskiAdd1MinkowskiAdd1, 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.
An empty 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,
draw_regiondraw_regionDrawRegiondraw_regionDrawRegionDrawRegion, gen_region_polygongen_region_polygonGenRegionPolygongen_region_polygonGenRegionPolygonGenRegionPolygon,
gen_region_pointsgen_region_pointsGenRegionPointsgen_region_pointsGenRegionPointsGenRegionPoints, etc.
A Minkowski addition always results in enlarged regions.
Closely spaced regions which may touch or overlap as a result of the
dilation are still treated as two separate regions. If the desired
behavior is to merge them into one region, the operator
union1union1Union1union1Union1Union1 has to be called first.
- 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_add2minkowski_add2MinkowskiAdd2minkowski_add2MinkowskiAdd2MinkowskiAdd2 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.
