What's the meaning of several parametes in default.yaml?

[yancx8]

foreground_loss_weight: 0 bbox_drop_ratio: 0 bbox_add_ratio: 0 bbox_add_num: 3

I find the bboxs cannot completely cover the target, if i change the parameters above,can it be improved? Thank you very much!

FYI:

• foreground_loss_weight: Not implemented/tested, cr GeoDiffusion (https://arxiv.org/abs/2306.04607)
• bbox_drop_ratio: random ratio to drop visible boxes on each view
• bbox_add_ratio: random ratio to add invisible boxes on each view
• bbox_add_num: number to add invisible boxes, work with bbox_add_ratio

For more information about visibility, please refer to Appendix A of our paper.

Here in our model, we randomly add unseen bboxes for augmentation. However, dropping may not help. You may try different parameters in your case.
