A Statistically-Assisted Sketch-Based Interface for Creating Arbitrary 3-dimensional Faces [article]

Orn Gunnarsson, Steve Maddock
2007 Computer Graphics and Visual Computing  
Our work involves bringing together two types of graphics applications: sketching interfaces and systems used to create 3-dimensional faces, through the mediation of a statistical model.  ...  We present our results where we sketch a nose and search for a geometric face model in a database whose nose best matches the sketched nose.  ...  Computer-based sketching interfaces aim to do the reverse process of reconstructing 3dimensional objects using a 2-dimensional sketch.  ...
