I am reading about different approaches for 3D facial reconstruction and can't get a difference between Shape-From-Stereo (SFS) and Shape-From-Motion (SFM) approaches.The SFS regresses a shape from few images looking for corresponded features points but it seems the SFM works with few images too. So what's a difference?
Can someone explain me a difference?
P.S. I can't find suitable tags due to my English level who knows well-suitable tags, pls, fix my question.
