Analyze

view_options_analyze

Correctness threshold

In the Analyze tab of Detection, Segmentation, and Optical Character Recognition mode, users can adjust a correctness threshold, which determines whether the inspection is correct by comparing the actual label area to the detected area. The actual labels or predictions above the set value are determined to be correct.

Detection: It is an IOU (intersection over union) value between the actual label and detected one, which is calculated as "(area of intersection) / (area of union)".
Segmentation: In the case of the actual label, it is calculated as "(area of intersection between the actual label and detected one) / (area of the actual label)". In the case of the detected label, it is calculated as "(area of intersection between the actual label and detected one) / (area of the actual label)".
Optical Character Recognition: It is an IOU (intersection over union) value between the actual label and detected one, which is calculated as "(area of intersection) / (area of union)".
