= 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:'''<<BR>>

{{attachment:P2F6TG3A0001_resized40pt.jpg}}

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.
