[request] Non-maximum Suppression (NMS)

[Athospd]

Hello! I would like to humbly make a request regarding NMS operator. I am currently working on porting this face detection and recognition implementation from py to R.

And to do so, NMS operator is required when boxing the detected faces.

I would be pleased to PR it myself, but it seems to be in C++ level and I felt insecure regarding autogens/best practices/compilers/stuff that you might reuse from torch devel toolkit itself.

I am open to be guided if needed to contribute with this. Also, I felt free to open a PR for boxes.py translation that is the task most beneficiated by NMS.

related links to what I'm talking about:

• nms.cpp
• torchvisio.ops.boxes.nms that uses torch.nms

Thank you very much!
