Can you explain the code of gaussian_radius in the utils/transform.py

[Qinying-Liu]

In your paper, it is said that 'We determine the radius by the size of an object by ensuring that a pair of points within the radius would generate a bounding box with at least tIoU with the ground-truth annotation'. I know what it means. However, I don't understand the actual implementation in your code. Can you explain it for us? It will be better if you add some annotations in the code.
