Name

hit_or_miss_golayhit_or_miss_golayHitOrMissGolayHitOrMissGolay — Hit-or-miss operation for regions using the Golay alphabet.

Signature

Description

hit_or_miss_golayhit_or_miss_golayHitOrMissGolayHitOrMissGolayHitOrMissGolay performs the hit-or-miss-transformation for the input regions RegionRegionRegionRegionregion (using structuring elements from the Golay alphabet). First, an erosion with the foreground of the structuring element GolayElementGolayElementGolayElementGolayElementgolayElement is done on the input region RegionRegionRegionRegionregion. Then an erosion with the background of the structuring element GolayElementGolayElementGolayElementGolayElementgolayElement is performed on the complement of the input region. The intersection of the two resulting regions is the result RegionHitMissRegionHitMissRegionHitMissRegionHitMissregionHitMiss of hit_or_miss_golayhit_or_miss_golayHitOrMissGolayHitOrMissGolayHitOrMissGolay. The following structuring elements are available:

'l', 'm', 'd', 'c', 'e','i', 'f', 'f2', 'h', 'k'.

The rotation number RotationRotationRotationRotationrotation determines which rotation of the element should be used. The hit-or-miss-transformation selects precisely the points for which the conditions given by the selected Golay element are fulfilled.

Attention

Not all values of RotationRotationRotationRotationrotation are valid for any Golay element.

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. Then the runtime complexity for one region is:

Result

hit_or_miss_golayhit_or_miss_golayHitOrMissGolayHitOrMissGolayHitOrMissGolay 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.
