The Light Field Camera: Extended Depth of Field, Aliasing and Superresolution
Published on Jan 23, 20127381 Views
Portable light field cameras have demonstrated capabilities beyond conventional cameras. In a single snapshot, they enable digital image refocusing, i.e., the ability to change the camera focus after
