thickeningthickeningThickeningThickeningthickening (Operator)

Name

thickeningthickeningThickeningThickeningthickening — Add the result of a hit-or-miss operation to a region.

Warning

thickeningthickeningThickeningThickeningThickeningthickening is obsolete and is only provided for reasons of backward compatibility.

Signature

Description

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

For the choice of the structuring elements StructElement1StructElement1StructElement1StructElement1structElement1struct_element_1 and StructElement2StructElement2StructElement2StructElement2structElement2struct_element_2, as well as for RowRowRowRowrowrow and ColumnColumnColumnColumncolumncolumn, the same restrictions described under hit_or_misshit_or_missHitOrMissHitOrMissHitOrMisshit_or_miss apply.

The structuring elements (StructElement1StructElement1StructElement1StructElement1structElement1struct_element_1 and StructElement2StructElement2StructElement2StructElement2structElement2struct_element_2) can be generated by calling golay_elementsgolay_elementsGolayElementsGolayElementsGolayElementsgolay_elements, for example.

Attention

If the reference point is contained in StructElement1StructElement1StructElement1StructElement1structElement1struct_element_1 the input region remains unchanged.

Execution Information

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

Parameters

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

thickeningthickeningThickeningThickeningThickeningthickening 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>)set_system("no_object_result",<RegionResult>)SetSystem("no_object_result",<RegionResult>)SetSystem("no_object_result",<RegionResult>)SetSystem("no_object_result",<RegionResult>)set_system("no_object_result",<RegionResult>)

• empty region: set_system('empty_region_result',<RegionResult>)set_system("empty_region_result",<RegionResult>)SetSystem("empty_region_result",<RegionResult>)SetSystem("empty_region_result",<RegionResult>)SetSystem("empty_region_result",<RegionResult>)set_system("empty_region_result",<RegionResult>)

Otherwise, an exception is raised.
