描述

fittingfittingFittingFittingFittingfitting performs an openingopeningOpeningOpeningOpeningopening and a closingclosingClosingClosingClosingclosing successively on the input regions. The eight structuring elements normally used for this operation can be generated with the operator gen_struct_elementsgen_struct_elementsGenStructElementsGenStructElementsGenStructElementsgen_struct_elements。However, other user-defined structuring elements can also be used. Let R be the input region(s) and let 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: Regions larger than the structuring elements are preserved, while small gaps are closed.

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）。
• 未采用并行化处理。

参数

结果

fittingfittingFittingFittingFittingfitting 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。
