Description

thickeningthickeningThickeningThickeningThickening performs a thickening of the input regions using morphological operations. The operator first applies a hit-or-miss-transformation to RegionRegionRegionRegionregion (cf. hit_or_misshit_or_missHitOrMissHitOrMissHitOrMiss), and then adds the detected points to the input region. The parameter IterationsIterationsIterationsIterationsiterations determines the number of iterations performed.

For the choice of the structuring elements StructElement1StructElement1StructElement1StructElement1structElement1 and StructElement2StructElement2StructElement2StructElement2structElement2, as well as for RowRowRowRowrow and ColumnColumnColumnColumncolumn, the same restrictions described under hit_or_misshit_or_missHitOrMissHitOrMissHitOrMiss apply.

The structuring elements (StructElement1StructElement1StructElement1StructElement1structElement1 and StructElement2StructElement2StructElement2StructElement2structElement2) can be generated by calling golay_elementsgolay_elementsGolayElementsGolayElementsGolayElements, for example.

Attention

If the reference point is contained in StructElement1StructElement1StructElement1StructElement1structElement1 the input region remains unchanged.

Complexity

Let F be the area of an input region, F1 the area of the structuring element 1, and F2 the area of the structuring element 2. Then the runtime complexity for one object is:

Result

thickeningthickeningThickeningThickeningThickening returns 2 (H_MSG_TRUE) if all parameters are correct. The behavior in case of empty or no input region can be set via:

Otherwise, an exception is raised.
