Thank you for great project.

Could you please define what is 'Metrical Reconstruction'?

In paper it is mentioned about 'Metrical space', do you mean 'Metric Space'?

After reconstruction with MICA, I checked the sizes of bounding boxes, and it looks like that the size is given in mm:

File: me.ply
Size X: 203.32 
Size Y: 309.37 
Size Z: 221.27 

File: daughter.ply
Size X: 197.41 
Size Y: 301.95 
Size Z: 216.75 

File: mesh_mica_prof_orig.ply
Size X: 220.28 
Size Y: 321.00 
Size Z: 220.72

Also I want to mention, that my Mica model exactly resembles my daughter's Mica model, just the size is slightly differs. Here's our models, my daughter on the left side:

As it is flame topology i what is the scale parameter to rescale MICA model into FLAME? Do you know? I think scale parameter is 0.00373773 to frame MICA the same size as Flame.

Recovering the correct scale from monocular images is still an ongoing research problem and the meshes may have the wrong size.
