seems to a bug?

[clelouch]

it seems that the mask_scores = 0.3 * mask_iou + bbox_score

[clelouch]

if i am right, it should be "if label is not None"?

@clelouch Thanks for interest. I am sorry that I donot clean the code very well. It is 0.3 * mask_iou + bbox_score. We donot use the original multiplication in mask scoring paper. We always implement the code in L344.

Thanks for your reply. I am curious

1. how your determine the value of the hyperparameter (i.e. 0.3 ) and
2. compared with the original multiplication in mask scroing rcnn, how much difference it makes .
3. Besides, why you choose such a way to generate the mask score?
4. is the D2Det sensitive to the hyperparameter(i.e. 0.3 )?
   looking forward to your reply!
