shoule i change both roi's loss_bbox and rpn's loss_bbox from l1 loss to ciou loss ,and for doule shared head ?

我注意到你在table 5 中对比了在普通3DIOU指导下的iou ciou diou loss以及在RDIOU指导下的iou ciou diou loss,所以我现在有个问题,在RDIOU指导下针对旋转的iou计算是根据角度计算了一个系数,那么在原始3DIOU指导下的iou ciou diou loss中的iou计算是通过什么方式呢,在代码中有给出吗?

你好,我看到这里对boxes做了sigmoid映射,在论文中还想没有提及,有什么用意吗?

Thank you very much for sharing!
Is the loss function you use in the network GIoU or CIoU?

May I ask why you use F.binary_cross_entropy for loss_xy while you use F.mse_loss for loss_wh?
And, (1) why did you divide by 2 for loss_wh? (you didn't divide by 2 for loss_xy)
(2) I thought that y…

Hi @mkang315
I would like to inquire about the wIoU loss function. If I want to implement wIoU based on your code, would any settings need to be changed?
I already follow your notes. But I jus…
