Align Sections (Feature Centroid)

Group (Subgroup)

Reconstruction Filters (Alignment)

Description

This filter attempts to align consecutive serial sections by determining the position that closest aligns the centroid(s) of previously defined "regions". The "regions" are defined by a binary/boolean array where the Cells have been flagged by another filter. Typically, during reading of the data, each Cell is subject to a "Quality Metric" (or threshold) that defines if the Cell is "good". This threshold can be used to define areas of each slice that are bad, either due to actual features in the microstructure or external references inserted by the user/experimentalist. If these "regions" of "bad" Cells are believed to be consistent through sections, then this filter will preserve that by aligning those "regions" on top of one another on consecutive sections. The algorithm of this filter is as follows:

  1. Determine the centroid of all Cells that are flagged with a boolean value of one (or true) for each section
  2. Determine the full Cell shifts that place centroids of consecutive sections as close as possible. Note that this is algorithm cannot get caught in a local minima
