Issue about loss function

[seekFire]

Thank you for your work! I'm very interested in it. In your paper, the step 4 in algorithm of loss function is shown as follows:

4: compute L CDIoU = L IoUs + diou, L IoUs could be L IoU = − ln(IoU ), L IoU = 1− IoU , L IoU = 1− IoU or L DIoU , L CIoU ;

Do you think whether the bold part is wrong? Is it L GIoU instead? BTW, whether the CDIoU loss could be another format? For example: L CDIoU = 1 - CDIoU or L CDIoU = - ln(CDIoU)
