Sample vs Point #34

Closed EchoQiHeng closed 1 month ago

Thank you for sharing your code. I am confused about the difference between "sample_indices" and "nmsed_indices." I don’t understand why random sampling is applied to the nmsed_points instead of using all the nmsed_points. What is the motivation behind this? Looking forward to your reply.

Hi, could you clarify which part of the code you were looking at?

During inference if I remember correctly we do use all the NMS-ed points.
