描述

closing_golayclosing_golayClosingGolayClosingGolayClosingGolayclosing_golay is defined as a Minkowski addition followed by a Minkowski subtraction. First the Minkowski addition of the input region (RegionRegionRegionRegionregionregion) with the structuring element from the Golay alphabet defined by GolayElementGolayElementGolayElementGolayElementgolayElementgolay_element and RotationRotationRotationRotationrotationrotation is computed. Then the Minkowski subtraction of the result and the structuring element rotated by 180 degrees is performed.

The following structuring elements are available:

'l', 'm', 'd', 'c', 'e', 'i', 'f', 'f2', 'h', 'k'.

The rotation number RotationRotationRotationRotationrotationrotation determines which rotation of the element should be used, and whether the foreground (even) or background version (odd) of the selected element should be used. The Golay elements, together with all possible rotations, are described with the operator golay_elementsgolay_elementsGolayElementsGolayElementsGolayElementsgolay_elements.

closing_golayclosing_golayClosingGolayClosingGolayClosingGolayclosing_golay serves to close holes smaller than the structuring element, and to smooth regions' boundaries.

注意

Not all values of RotationRotationRotationRotationrotationrotation are valid for any Golay element. For some of the values of RotationRotationRotationRotationrotationrotation, the resulting regions are identical to the input regions.

执行信息

• Multithreading type: reentrant (runs in parallel with non-exclusive operators).
• Multithreading scope: global (may be called from any thread).
• Automatically parallelized on tuple level.

参数

Complexity

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

结果

closing_golayclosing_golayClosingGolayClosingGolayClosingGolayclosing_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>)set_system("no_object_result",<RegionResult>)SetSystem("no_object_result",<RegionResult>)SetSystem("no_object_result",<RegionResult>)SetSystem("no_object_result",<RegionResult>)set_system("no_object_result",<RegionResult>)

• empty region: set_system('empty_region_result',<RegionResult>)set_system("empty_region_result",<RegionResult>)SetSystem("empty_region_result",<RegionResult>)SetSystem("empty_region_result",<RegionResult>)SetSystem("empty_region_result",<RegionResult>)set_system("empty_region_result",<RegionResult>)

Otherwise, an exception is raised.
