thickening_golaythickening_golayThickeningGolayThickeningGolayThickeningGolay performs a thickening of the input regions using morphological operations and structuring elements from the Golay alphabet. The operator first applies a hit-or-miss-transformation to RegionRegionRegionRegionregion (cf. hit_or_miss_golayhit_or_miss_golayHitOrMissGolayHitOrMissGolayHitOrMissGolay), and then adds the detected points to the input region. 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 Golay elements, together with all possible rotations, are described with the operator golay_elementsgolay_elementsGolayElementsGolayElementsGolayElements.


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

Let F be the area of an input region. Then the runtime complexity for one region is:


thickening_golaythickening_golayThickeningGolayThickeningGolayThickeningGolay 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.
