当图中没有prompt提示的物品时，会把最大的物品当做prompt提示的物品

输入的prompt为sun /cat/ dog 等。图中圈出来的都有问题：

下面这个是原图：

There does appear to be an issue with the control over counterexamples in the Grounding-DINO model. This may be due to the model's weights. It might be worth trying better weights to see if it alleviates such a problem.

Thx, i will try with another model weight.

Sorry, could you please confirm again if you are referring to replacing the model or adjusting the parameters in GroundingDINO_SwinB.cfg.py?

Need i change models blow or adjusting config?

我个人实践，在openset上用Grounding-DINO在上做开放目标检测，有些理解

1. text prompt尽量多测试，并且用地道英语（1cat我都不太能理解），一般框都挺准，但可能和text对不上
2. box thresh可以调高些，但text thresh过高会出现断词的现象
3. 对于box占全图过大的case就过滤掉
4. 加些启发式联合过滤，比如衣服一定有人脸
5. openset的zero short 不可避免地会有误检，只能说在大数据范围内准确率还有个60%多，剩下的还得double check
