描述
closing_golayclosing_golayClosingGolayClosingGolayClosingGolayclosing_golay 被定义为先执行明可夫斯基加法，再执行明可夫斯基减法。首先计算输入区域（RegionRegionRegionRegionregionregion）与由
GolayElementGolayElementGolayElementGolayElementgolayElementgolay_element 和 RotationRotationRotationRotationrotationrotation 定义的 Golay 字母表中结构元素的明可夫斯基加法结果。随后对该结果与旋转 180 度的结构元素执行明可夫斯基减法。
以下结构化元素可用：
'l', 'm', 'd', 'c', 'e', 'i', 'f', 'f2', 'h', 'k'。
旋转数 RotationRotationRotationRotationrotationrotation 决定应使用元素的哪个旋转版本，以及应使用所选元素的前景（偶数）版本还是背景（奇数）版本。Golay 元素及其所有可能的旋转均由算子 golay_elementsgolay_elementsGolayElementsGolayElementsGolayElementsgolay_elements 描述。
closing_golayclosing_golayClosingGolayClosingGolayClosingGolayclosing_golay 用于闭合小于结构单元的孔洞，并平滑区域边界。
注意
并非所有 RotationRotationRotationRotationrotationrotation 值都适用于任意 Golay 元素。对于某些 RotationRotationRotationRotationrotationrotation 值，生成的区域与输入区域完全相同。
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
设 F 为输入区域的面积。则单个区域的运行时间复杂度为：
结果
closing_golayclosing_golayClosingGolayClosingGolayClosingGolayclosing_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。
