There are multiple bounding boxes on a single object.

[Ian-Work-AI]

The model works well in most cases, but sometimes it detects multiple bounding boxes for the same single object. The DETR paper says that the model will generate an independent bounding box for each individual target, so they didn't need NMS. Shouldn't the output keep only the highest scoring bounding box?

Thanks for your help!!

I do have the same issue too. I obtain several perfectly overlapping boxes with different classes and even boxes with high IoU with the same label. Have you ever noticed that @lyuwenyu ?

I think you should choose score threshold carefully.

@lyuwenyu 应该不是分数阈值设置合理性的问题吧，会出现分数非常相近的几乎重叠的情况
