描述

thinningthinningThinningThinningThinningthinning performs a thinning of the input regions using morphological operations. 该算子 first applies a hit-or-miss-transformation to 区域区域区域区域区域区域 (cf. hit_or_misshit_or_missHitOrMissHitOrMissHitOrMisshit_or_miss), and then removes the detected points from the input region. The parameter IterationsIterationsIterationsIterationsiterationsiterations determines the number of iterations performed.

For the choice of the structuring elements StructElement1StructElement1StructElement1StructElement1structElement1struct_element_1 and StructElement2StructElement2StructElement2StructElement2structElement2struct_element_2, as well as for RowRowRowRowrowrow and ColumnColumnColumnColumncolumncolumn, the same restrictions described under hit_or_misshit_or_missHitOrMissHitOrMissHitOrMisshit_or_miss apply.

Structuring elements (StructElement1StructElement1StructElement1StructElement1structElement1struct_element_1, StructElement2StructElement2StructElement2StructElement2structElement2struct_element_2) can be generated with operators such as gen_circlegen_circleGenCircleGenCircleGenCirclegen_circle, gen_rectangle1gen_rectangle1GenRectangle1GenRectangle1GenRectangle1gen_rectangle1, gen_rectangle2gen_rectangle2GenRectangle2GenRectangle2GenRectangle2gen_rectangle2, gen_ellipsegen_ellipseGenEllipseGenEllipseGenEllipsegen_ellipse, draw_regiondraw_regionDrawRegionDrawRegionDrawRegiondraw_region, gen_region_polygongen_region_polygonGenRegionPolygonGenRegionPolygonGenRegionPolygongen_region_polygon, gen_region_pointsgen_region_pointsGenRegionPointsGenRegionPointsGenRegionPointsgen_region_points, etc.

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

Complexity

Let F be the area of an input region, F1 the area of the structuring element 1, and F2 the area of the structuring element 2. Then the runtime complexity for one object is:

结果

thinningthinningThinningThinningThinningthinning 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.
