About DSSIM Loss and opacity reset #152

Closed WuJH2001 closed 3 months ago

WuJH2001 commented 3 months ago

Hello, thanks to your contribution. I have some questions about your code, Why don't you use DSSIM loss, and reset opacity . Does the deformation field correctly model rigid motion, rather than a state fitted by multiple deformations? Looking forward to your reply.Thanks.

Hi, DSSIM may let training speed become slower. If you add this, the results will be better. Currently, deformation field cannot model rigid motion accurately there are some small errors :) maybe using tracking priors or flow as supervision will be better. Best wishes!
