Could you add Teaser++ as an option for the pairwise global registration?
This is a good proposal! We haven’t got this in my timeline, but I’m aware of their amazing work. I have tried their implementation and it is, I have to say, slow and not optimal now.
One research who is familiar with Luca’s group told me that usually they will first propose an algorithm that is very accurate, then take several iterations to improve the performance. We may integrate teaser++ once they reach that stage given that there is no license issues.
