Is it possible to fit scan mesh without landmark?

[dragonylee]

Thanks for your work!
I am using your code fit_scan.py to fit a mesh with arbitrary topology. It's hard to generate landmarks for all inputs. Is there any way to fit it without landmarks please?

Hi, did you get any ideas/solutions?

No, so when I was comparing them, I explained that their method requires providing landmarks.

Fitting the model to a scan minimizes follows some iterative closest point scheme, which alternates between computing correspondences between each scan vertex and the FLAME model mean, and minimizing the distance between these points in correspondence. As ICP-based methods converge only locally die to the unknown correspondence, a good initialization is required for this optimization. One common way is to assume the correspondence for few keypoints to be given. Without these keypoints, you will need to find some other way to initialize the optimization to get good initial correspondences for the ICP to work.
