# Evaluating Results

For each edge pattern candidate in the filtered projection image that exceeds the contrast threshold you supply, up to the number of results that you specify, the Caliper tool returns the following information:

- The position of the edge pattern candidate relative to the projection region center of the projection region
- The overall score for this edge pattern candidate, computed using the scoring methods you supplied
- The polarity and contrast of all edges in the edge pattern candidate
- The individual scores for each of the scoring methods you supplied

In addition, you can request the following additional information from the Caliper tool:

- The polarity and contrast of each individual edge in the filtered projection image
- The unfiltered projection image itself
- The filtered projection image itself
- The number of edge pattern candidates that exceeded the contrast threshold

You can use this optional information to perform your own processing and analysis of the intermediate data generated by the Caliper tool.
