Theta calculation and label normalization

[Jcastanyo]

Hello, my name is Julio,

First of all, I wanted to thank you for you hard work on this project.

I am working on a project where rotated-yolov5 should be the optimal solution. I am struggling with theta calculation and label normalization. I wonder if you could explain me how do you calculate theta angle from rectangular bounding boxes and, also, how do you normalize w,h, if you do it.

Thanks in advance.
