Normalized Cross-Correlation Evaluation

This page describes the methodology for using normalized cross-correlation to evaluate a region of the model.

Cross-correlation is performed on the following images:

  • Model: Image of bigmap
  • Truth: Image of Zmaps

Model (left), Truth (right), S/C Azimuth 0, Zenith 30deg, Sun Azimuth 90deg, Zenith 45deg:

Images are generated using the following set of dirty sumfiles at the required resolution to include:

  • low and high phase
  • low and moderate incidence
  • full set of s/c azimuth angles (observe region from all directions).

Images resolution is chosen from the following based on the state of the model:

  • Resolution: 120cm, 75cm, 35cm, 18cm, 9cm, 5cm.

Where are the Dirty Sumfiles and Truth Images?
