detections and groundtruth are swapped in calculate_iou_partly() function

[GaneshAdam]

Hello Author,

Thanks for the repo!
I am wondering why detections and groundtruth are swapped. like while calling it is called as calculate_iou_partly(dt_annotations, gt_annotations, ..) and in function definiton it is used as calculate_iou_partly(gt_annotations, dt_annotations, ..).
The results are different if we keep same ordering.

Hello, thank you for your issue.

This is a known problem that we inherited from the kitti_eval repo:
https://github.com/traveller59/kitti-object-eval-python/blob/master/eval.py#L365

You can see that it was also swapped here. Since the output use of the variables is also swapped, and this function is about matching rectangles and calculating their overlaps, it should not matter.

@BalazsSzekeres can you have a look?
