Recognition of 3D faces with missing parts based on profile networks
Stefano Berretti, Alberto Del Bimbo, Pietro Pala · 2010
3D face recognition solutions proposed so far compare face scans of a probe subject against archived face scans (gallery), assuming the entire scans are available for both probe and gallery. Though the assumption is reasonable for subjects in the gallery---gallery scans are typically acquired in controlled environments following a collaborative protocol---the same assumption is not general if applied to probes. In fact, when face recognition is performed in un-collaborative contexts, the acquired probes may correspond to just a part of the face or may be altered by occlusions.
