描述
thinning_golaythinning_golayThinningGolayThinningGolayThinningGolaythinning_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 RegionRegionRegionRegionregionregion (cf.
hit_or_miss_golayhit_or_miss_golayHitOrMissGolayHitOrMissGolayHitOrMissGolayhit_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 RotationRotationRotationRotationrotationrotation determines which rotation of
the element should be used. The Golay elements, together with all
possible rotations, are described with the operator
golay_elementsgolay_elementsGolayElementsGolayElementsGolayElementsgolay_elements。
注意
Not all values of RotationRotationRotationRotationrotationrotation are valid for any Golay
element.
执行信息
- 多线程类型：可重入（与非独占算子并行运行）。
- 多线程作用域：全局（可从任何线程调用）。
- 在元组级别上自动并行化。

复杂度
Let F be the area of an input region. Then the runtime complexity for one
region is:
结果
thinning_golaythinning_golayThinningGolayThinningGolayThinningGolaythinning_golay 在所有参数正确时返回 2 ( H_MSG_TRUE )。当输入区域为空或不存在时，其行为可通过以下方式设置：
-
无区域：
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>)
-
空区域：
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>)
否则，将抛出异常。
