Find Feature Neighborhoods

Group (Subgroup)

Statistics (Morphological)

Description

This Filter determines the number of Features, for each Feature, whose centroids lie within a distance equal to a user defined multiple of the average Equivalent Sphere Diameter (*average of all Features). The algorithm for determining the number of Features is given below:

  1. Define a sphere centered at the Feature's centroid and with radius equal to the average equivalent sphere diameter multiplied by the user defined multiple
  2. Check every other Feature's centroid to see if it lies within the sphere and keep count and list of those that satisfy
  3. Repeat 1. & 2. for all Features

Parameters

Name Type Description
Multiples of Average Diameter float Defines the search radius to use when looking for "neighboring" Features
