ClassifyPaths

Basic

Module: FoundationBasic

Splits the paths of the input array - in accordance to the relation between computed feature values and the specified range.

Applications

Use this filter when you have an array of paths and you want to select some of them for further processing.

Description

The filter accepts an array of paths and splits it into output arrays, depending on how each of the computed feature values fits the (inMinimum, inMaximum) range.

  • Paths corresponding to feature values lower than inMinimum are passed onto outBelow and outRejected.
  • Paths corresponding to feature values that fit closed range (inMinimum, inMaximum) are passed onto outAccepted.
  • Paths corresponding to feature values higher than inMaximum are passed onto outAbove and outRejected.

In the special case of inMinimum being greater than inMaximum, first matching condition is applied, which means that objects corresponding to values higher than inMaximum and lower than inMinimum are passed onto outBelow.

Paths can be filtered before classification. One can process all paths, only open or only closed ones, depending on value of inPathFilter input.

To learn about possible features to classify paths, one should see PathFeature documentation. To know details about particular feature, corresponding filter article should be read.

Hints

  • Connect an array of paths to the inPaths input.
  • Using the inFeature input select a feature that well separates the interesting objects.
  • Using the inPathFilter input you can also separate only closed or only open paths.
  • Set the range of inMinimum and inMaximum to define the accepted objects. Refer to the outValues output to see the feature values for all input objects.

Complexity Level

This filter is available on Basic Complexity Level.

  • ClassifyByRange – Separates the elements of the input array into three output arrays, depending on whether the related values fall below, into or above the specified range.
  • GetMaximumPath – Returns the path from the input array that corresponds to the largest computed feature value.
  • GetMinimumPath – Returns the path from the input array that corresponds to the smallest computed feature value.
  • SortPaths – Changes the order of paths from the input array according to an ascending/descending sequence of their computed feature values.
  • SelectOuterPaths – Selects paths which do not obstruct visibility of other paths from a point.
