描述

morph_skizmorph_skizMorphSkizMorphSkizMorphSkizmorph_skiz first performs a sequential thinning (thinning_seqthinning_seqThinningSeqThinningSeqThinningSeqthinning_seq) of the input region with the element 'l' of the Golay alphabet. The number of iterations is determined by the parameter Iterations1Iterations1Iterations1Iterations1iterations1iterations_1. Then a sequential thinning of the resulting region with the element 'e' of the Golay alphabet is carried out. The number of iterations for this step is determined by the parameter Iterations2Iterations2Iterations2Iterations2iterations2iterations_2. The skiz operation serves to compute a kind of skeleton of the input regions, and to prune the branches of the resulting skeleton. If the skiz operation is applied to the complement of the region, the region and the resulting skeleton are separated.

If very large values or 'maximal' are passed for Iterations1Iterations1Iterations1Iterations1iterations1iterations_1 or Iterations2Iterations2Iterations2Iterations2iterations2iterations_2, the processing stops if no more changes occur.

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。

Complexity

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

结果

morph_skizmorph_skizMorphSkizMorphSkizMorphSkizmorph_skiz 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.
