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 ...

The big picture: The Internet has long demonstrated the potential hazard involving unintentional reflections in photos ... along with recent advancements in 3D vision and graphics, the team ...
