thinning_golay — Remove the result of a hit-or-miss operation from a region (using a Golay structuring element).
thinning_golay is obsolete and is only provided for reasons of backward compatibility.
thinning_golay(Region : RegionThin : GolayElement, Rotation : )
thinning_golay performs a thinning of the input regions using morphological operations and structuring elements from the Golay alphabet. The operator first applies a hit-or-miss-transformation to Region (cf. hit_or_miss_golay), and then removes the detected points from the input region. The following structuring elements are available:
'l', 'm', 'd', 'c', 'e', 'i', 'f', 'f2', 'h', 'k'.
The rotation number Rotation determines which rotation of the element should be used. The Golay elements, together with all possible rotations, are described with the operator golay_elements.
Not all values of Rotation are valid for any Golay element.
Regions to be processed.
Result of the thinning operator.
Structuring element from the Golay alphabet.
Default value: 'h'
List of values: 'c', 'd', 'e', 'f', 'f2', 'h', 'i', 'k', 'l', 'm'
Rotation of the Golay element. Depending on the element, not all rotations are valid.
Default value: 0
List of values: 0, 2, 4, 6, 8, 10, 12, 14, 1, 3, 5, 7, 9, 11, 13, 15
Let F be the area of an input region. Then the runtime complexity for one region is:
thinning_golay 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.
