Detection Statistics and Trial List

Subject Not Found

The percentage and number of samples in which the subject was not found. This information is useful to check the quality of detection in general. When a subject is not found, it means that EthoVision XT processed the image, but did not find anything matching the current Detection Settings. Use Subject Not Found to assess the quality of tracking.

When you select another video file, or click Save Changes, the value for Subject Not Found is reset to zero.

Note: This correction is not applied when the subject is not found for reasons other than dropped frames, for example when the subject is out of view.

Warning Color Thresholds

The percentages of missed samples, interpolated samples and samples where the subject is not found are usually displayed in green for each arena and subject. When the values are above the set threshold, they are highlighted in red. This helps you monitor the quality of tracking and spot detection issues.

Click the button under Missed Samples, Interpolated Samples or Subject Not Found to change the thresholds.
