Reproducing COCO-Val results on Qwen2_VL

[Sephirex-X]

Hi, is there any specific setting (e.g. post-process) that's needed to reproduce the results of COCO-val on Qwen2_VL? I've tried the prompt in your paper but only obtained ~20% PR@50 on COCO-val.

For example, the left image is from your paper, and the right image is my detected bbox using Qwen2-VL-7B, the backpack and tennis racket is not recognized.
