Question about Least Kinetic Motion Prior #36

Open rliu100 opened 1 year ago

rliu100 commented 1 year ago

Hi, I was wondering why

sf_sm_loss += args.w_sm * compute_sf_lke_loss(ret['raw_pts_ref'], 
                                                    ret['raw_pts_post'], 
                                                    ret['raw_pts_prev'], 
                                                    H, W, focal)

is called twice at the following two lines?:

https://github.com/zhengqili/Neural-Scene-Flow-Fields/blob/86ad6ddd1ce1c758bc908ef022ce843aae323d50/nsff_exp/run_nerf.py#L593

Should compute_sf_lke_loss compute the $L_{temp}$ term?

Thank you!

Have you figured it out? I have the same question.
