hit_or_miss_seqhit_or_miss_seqhit_or_miss_seqHitOrMissSeqHitOrMissSeq (Operator)

Name

hit_or_miss_seqhit_or_miss_seqhit_or_miss_seqHitOrMissSeqHitOrMissSeq — Hit-or-miss operation for regions using the Golay alphabet (sequential).

Signature

Description

hit_or_miss_golayhit_or_miss_golayhit_or_miss_golayHitOrMissGolayHitOrMissGolay performs the hit-or-miss-transformation for the input regions RegionRegionRegionRegionregion 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_elementsgolay_elementsgolay_elementsGolayElementsGolayElements.

Parallelization

• 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, and R be the number of rotations. Then the runtime complexity for one region is:

      O(R * 6 * sqrt(F)) .

Result

hit_or_miss_seqhit_or_miss_seqhit_or_miss_seqHitOrMissSeqHitOrMissSeq 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.
