fittingfittingfittingFittingFitting (Operator)

Name

fittingfittingfittingFittingFitting — Perform a closing after an opening with multiple structuring elements.

Signature

Description

fittingfittingfittingFittingFitting performs an openingopeningopeningOpeningOpening and a closingclosingclosingClosingClosing successively on the input regions. The eight structuring elements normally used for this operation can be generated with the operator gen_struct_elementsgen_struct_elementsgen_struct_elementsGenStructElementsGenStructElements. However, other user-defined structuring elements can also be used. Let R be the input region(s) and let M(i) denote the structuring elements. Furthermore, let P be the result of the opening and Q be the final result. Then the operator can be formalized as follows:

           n
          |  |
      P = |  | R o M      (opening)
          \__/      i
          i=1

           n_
          /  \
      Q = |  | P * M      (closing)
          |  |      i
          i=1

Regions larger than the structuring elements are preserved, while small gaps are closed.

Parallelization

• Multithreading type: reentrant (runs in parallel with non-exclusive operators).
• Multithreading scope: global (may be called from any thread).
• Processed without parallelization.

Parameters

Result

fittingfittingfittingFittingFitting 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.
