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.
