How to reimplement IACS? #24

Open RichardcLee opened 2 years ago

RichardcLee commented 2 years ago

I want to reimplement VFNet by detectron2. Can you describe the technical details of implementing it in detail? please.

RichardcLee commented 2 years ago

and Why do you use this function：clamp(min=1e-6) ?

hyz-xmaster commented 2 years ago

Hi, this repo is implemented using the framework of MMDetection which you may need to get familiar with.

VFNet mainly involves a new loss, Varifocal Loss, and a detector head, vfnet_head. Most of the details are in these two scripts and understanding them is almost enough to reimplement VFNet.

clamp(min=1e-6) ?

This is to avoid the calculated IoU to be 0.
