Dear Marcel,
You are correct, for the parametric I forgot the mouth cone and after correction, it did result in a 'normal' face but not an identical one (figure 1).
For the ICP version, I tried the multiplication and it also improved the results, the mouth is a better fit now (figure 2) but still not as identical as I had hoped. Can the shape difference with ICP be explained by the way I define the correspondence? I have placed landmarks on the reference modelmesh and used attribute correspondences to find their corresponding points on the targetface. When using the function nonrigid ICP I assign the mean mesh of the model as the moving mesh. As I believe you did too in tutorial 11.
If you mean the overall shape of the face with the artefacts, this is from the first iteration for non-rigid. For the parametric version, the deformation is happening in the end stage. I tried it with fewer iterations but there was no clear difference in the result.
Kind regards,
Masu de Ridder
