Signature

hit_or_miss_golay(Region : RegionHitMiss : GolayElement, Rotation : )

Description

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

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

The rotation number RotationRotationRotationRotationrotationrotation 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 RotationRotationRotationRotationrotationrotation 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_golayHitOrMissGolayHitOrMissGolayHitOrMissGolayhit_or_miss_golay returns 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.
