In order to reduce the error in three-dimensional shape recovery using traditional 4-source photometric stereo method when the highlight and shadow exist in the input images simultaneously,a new 4-source normal vector selection algorithm is presented.

3-D profile measurement for plasma spray rapid tooling visualization system;

This paper presents a new method to measure the 3D shape of an obj ect by the technique of proj ection of Ronchi grating and the subsequent moire phase-shifting to restore the image.

one of approaches to face recognition with pose variation is to deal with pose variation in 3D space,but how could we get the 3D shape of a face from corresponding 2D face images is a key issue.

Survey on the research status of 3D facial reconstruction;

The technology of computer aided 3D facial reconstruction is widely applied in the fields of criminalistics, archeology and so on.
