Grouping Density

This filter will calculate the grouping densities for specific Parent Features. This filter is intended to be used for hierarchical reconstructions (i.e., reconstructions involving more than one segmentation; thus, the Feature-Parent Feature relationship). The filter will iterate through all Features that belong to each Parent Feature, querying each of the Feature Neighbors to determine if it was checked during grouping. A list of Checked Features is kept for each Parent Feature. Then, each Parent Volume is divided by the corresponding total volume of Checked Features to give the Grouping Densities.

If non-contiguous neighbors were used in addition to standard neighbors for grouping, then a Use Non-Contiguous Neighbors Parameter may be used.

Since many Checked Features are checked by more than one Feature during grouping, a premium is placed on the Parent Feature querying the Checked Feature having the largest Parent Volume. For Checked Features to be written, a Find Checked Features Parameter may be used.
