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.
