# Parameter Search Results for Blue Tools

The search results of a Blue Locate/Read tool includes Feature Metrics (the Precision, Recall, F-score calculated per feature) and Model Metrics (the Precision, Recall, F-score calculated per model). See / for the details.

There are other Blue Locate/Read result metrics that are currently only shown in the Parameter Search Utility.

- Feature Size Difference

- Feature Angle Difference

- Feature Position Distance

For Blue Locate/Read, a found feature is said to be correctly found (marked) if there is a labeled feature relatively close. For each correctly found feature, you can compute the position distance, angle difference, and size difference by comparing that correctly found feature to the labeled feature. The reported Feature Position Distance, Feature Angle Difference, and Feature Size Difference in result table are “average feature position distance,” “average angle difference,” and “average size difference” (root-mean-square averages), respectively, calculated over all correctly found features.

Metrics | Description
Feature Size Difference | The difference of Feature Size between the correctly found feature and the labeled feature
Feature Angle Difference | The difference of Feature Angle between the correctly found feature and the labeled feature
Feature Position Distance | The difference of Feature Position between the correctly found feature and the labeled feature
