Dynamic photometric stereo—a new technique for moving surface analysis [PDF]

open access: yesImage and Vision Computing, 2005
This paper describes a novel approach for two- and three-dimensional surface data capture from moving surfaces based upon an evolution of the existing photometric stereo (PS) technique. Limitations in current methods are described, together with the potential benefits of applying PS and the particular need for a new dynamic form of the method ...

Photometric techniques, performance and PSF characterization of GeMS [PDF]

open access: yesSPIE Proceedings, 2016
GeMS is the multi-conjugate adaptive optics instrument at the Gemini South telescope in Chile, the first facility-class MCAO system and the first to use laser guide stars. During its science verification period we have observed the Galactic globular cluster NGC 1851 and here we discuss the optimization of the analysis techniques that we adopt to ...
