Hi, We can reproduce this issue internally. The reason of this issue is that there is no NMS (non maximum suppression) in your parser. It is a common requirement for the detector. Please find a introduction below: [image] Non-maximum suppression | Towards Data Science Remove redundan…

Hi, Could you share more information with us? Which sample do you use? How do you modify the config for the custom model? Thanks.

This is config.

Hi, Do you use a USB camera? Could you check if this issue can be reproduced with a video? If yes, please share the video with us for debugging. Thanks.

Hi, Just want to confirm the issue first. The problem is there are too many bounding boxes. Is that correct? Since we saw some unusual green and red regions in the first output. But the issue is gone in the second output you shared. Thanks.

Hi, Problem is too many bounding boxes. In first picture there is too many of them they just paint the screen. Its also occurs in video time to time I just couldn’t capture it. Thanks

Hi, We try to reproduce this issue in our environment but get some error from the post-processing. It seems that you have a custom nvdsinfer_customparser, could you also share the source with us? Thanks.

Hi, I assume you are asking for this. nvdsinfer_customclassifierparser.cpp (4.3 KB) Thanks.

any progress on this? could you share the steps how to train on pascal VOC? thanks!

Hi,

No progress yet.

You can see my related question here about training.

I used cvat for annotation and export as Pascal VOC dataset for training.

Thanks.
