Web29 jul. 2024 · Our analysis showed that the ARD model performed better than the image strip model at all thresholds, with the difference in performance increasing for greater IOU thresholds. The ARD model outperformed the image strip model by more than 12% at an IOU of 50% and had an AP50 of 0.78 compared to the image strip’s 0.69. WebMatching algorithm is based on Intersection over union ( IoU ) and Hungarian Algorithm. A threshold parameter for IoU is used for identifying the detections as False positives or True Negatives. After applying the IoU algorithm, when there are any false positives or true negatives, corresponding image is flagged for the human intervention.
