How IoU is calculated between the detection and the trajectory?

[minho8849]

First, thanks for sharing your work. I read your good paper, but I have some question about it. In 1st level association, you proposed IoU between the i-th detection and j-th trajectory in equation (2) and (3) However, I cannot find the detailed equation about it. Can you give me detailed explanation or reference paper about calculating IoU between the detection and trajectory? Thanks for your help
