Question about IoU Metrics error #11

Closed Jinyang228 closed 2 years ago

Jinyang228 commented 2 years ago

Hi, sorry to bother you. The max value of metrics IoU is 1 and the mix is 0. The result shows 2700 and all of the results rather than 1.

Hi notablefire, The data is normalized w.r.t. the original publaynet dataset. All the values for original dataset are considered to be 1 and others are scaled accordingly.

The value of iou for original dataset would be very low because there is almost no overlap in the boxes (say 0.001). Now if some dataset has iou of 0.5, we have shown its iou as 0.5/0.001 = 500 and the iou of original dataset as 0.001/0.001 = 1.

The normzalizing is done in the second last block in these lines. `

normalizing the lists w.r.t the original data

overlist/=overlist[0] ioulist/=ioulist[0] alignlist/=alignlist[0] `

Thanks a lot.
