Hit-or-miss operation for regions using the Golay alphabet (sequential).
hit_or_miss_golay performs the hit-or-miss-transformation for the input regions Region using all rotations of a structuring element from the Golay alphabet. The result of the operator is the union of all intermediate results of the respective rotations. The following structuring elements are available:
'l', 'm', 'd', 'c', 'e', 'i', 'f', 'f2', 'h', 'k'.
The Golay elements, together with all possible rotations, are described with the operator golay_elements.
Region (input_object) |
region(-array) -> object |
Regions to be processed. |
RegionHitMiss (output_object) |
region(-array) -> object |
Result if the hit-or-miss operation. |
GolayElement (input_control) |
string -> string |
Structuring element from the Golay alphabet. | |
Default value: 'h' | |
List of values: 'l', 'm', 'd', 'c', 'e', 'i', 'f', 'f2', 'h', 'k' |
Let F be the area of an input region, and R be the number of rotations. Then the runtime for one region is:
O(R * 6 * sqrt(F)) .
hit_or_miss_seq returns TRUE if all parameters are correct. The behavior in case of empty or no input region can be set via:
a) no region: set_system(::'no_object_result',<RegionResult>:) b) empty region: set_system(::'empty_region_result',<RegionResult>:)Otherwise, an exception is raised.
