IOU Computation #16

Open liumusicforever opened 6 years ago

liumusicforever commented 6 years ago

Hello @zhreshold , I am so confuse about your IOU computation during training , can you explain the file at "train/metrix.py line 106" :

max_iou = np.amax(ious[:, j])

you only select one maximum IOU from each bboxes's IOU in each images , but why didn't you compute the average of each IOUs in each images ? And the second question is , why didn't you give the default threshold to compute IOU ?

Maybe I make something mistake , Can you explain the reason ?

It's for monitoring current training status, I just want to know the best iou during training, that's it.
