The circular problem of the rectify map of RPG (stereo davis) dataset

[Chensiyu00]

Thanks for your contribution. When I using the pp_rpg.py to proprocess the dataset, I visualize the rectified event map with rectified image. I found the circular problem shown as follow.

Have you encountered this problem before, and how did you solve it?

Thank you in advance.
