Accurate and robust 3D imaging of specular, or mirror-like, surfaces is crucial in fields such as industrial inspection, medical imaging, virtual reality, and cultural heritage preservation.

a) 3D view of the volcano obtained by confocal migration of the reflection matrix. The image obtained is blurred by distortions of seismic waves caused by the volcano’s heterogeneities.

Researchers from the University of Maryland have devised a way to extract those reflections from a photo and render it in 3D. The result is a sometimes accurate model of whatever happens to be in ...
