Webb17 aug. 2014 · For axis-aligned bounding boxes it is relatively simple. "Axis-aligned" means that the bounding box isn't rotated; or in other words that the boxes lines are parallel to the axes. Here's how to calculate the IoU of two axis-aligned bounding boxes. def get_iou(bb1, bb2): """ Calculate the Intersection over Union (IoU) of two bounding boxes. Webb2 dec. 2024 · Let’s calculate the AP for an IoU threshold of 0.75: Table 3: example with skewness towards IoU of 0.6 Table 4: example with skewness towards IoU of 0.9 Image 4: PR curve visualized for Table 3 Image 5: PR curve visualized for Table 4 Take note that in Table 3 we have detection 2 to 4 with an IoU less than our threshold which results into FP.
