closing_circleclosing_circleClosingCircleClosingCircleclosing_circle (算子名称)

名称

closing_circleclosing_circleClosingCircleClosingCircleclosing_circle — Close a region with a circular structuring element.

参数签名

描述

closing_circleclosing_circleClosingCircleClosingCircleClosingCircleclosing_circle behaves analogously to closingclosingClosingClosingClosingclosing, i.e., the regions' boundaries are smoothed and holes within a region which are smaller than the circular structuring element of radius RadiusRadiusRadiusRadiusradiusradius are closed. The closing_circleclosing_circleClosingCircleClosingCircleClosingCircleclosing_circle operation is defined as a dilation followed by a Minkowski subtraction, both with the same circular structuring element.

注意

closing_circleclosing_circleClosingCircleClosingCircleClosingCircleclosing_circle is applied to each input region separately. If gaps between different regions are to be closed, union1union1Union1Union1Union1union1 or union2union2Union2Union2Union2union2 has to be called first.

运行信息

• 多线程类型:可重入(与非独占操作符并行运行)。
• 多线程作用域:全局(可以从任何线程调用)。
• 在元组级别自动并行化。

参数表

例程 (C)

my_closing_circle(Hobject In, double Radius, Hobject *Out)
{
  Hobject  tmp, StructElement;
  gen_circle(StructElement,100.0,100.0,Radius);
  dilation1(In,StructElement,&tmp,1);
  minkowski_sub1(tmp,StructElement,Out,1);
}

Complexity

Let F1 be the area of the input region. Then the runtime complexity for one region is:

结果

closing_circleclosing_circleClosingCircleClosingCircleClosingCircleclosing_circle 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.
