A question regarding the calculation of ProbIOU. about ultralytics

[glenn-jocher]

Hello! Thank you for bringing this to our attention and for your detailed observation regarding the probiou calculation in YOLOv8.

The difference in the multiplication factors for t1 and t2 that you've noticed is indeed intentional. This adjustment in the code is based on further empirical testing and optimization beyond the initial publication. The goal was to enhance the performance and accuracy of the model in practical scenarios.

We appreciate your vigilance and encourage you to experiment with these parameters to see how they might affect your specific use cases. If you have further insights or questions, please feel free to share!

Happy coding! 🚀
