Light field applications to 3-dimensional surface imaging
… fields demonstrate their utility in performing digital refocusing, reconstructing occluded objects as well as accurately estimating depth and shape. The performance of the algorithms developed are discussed theoretically and compared empirically.

Image restoration from noisy and limited measurements with applications in 3D imaging
… is proposed. The system can be applied for digital refocusing on an arbitrary surface and for recovering complex reflectance information of a surface. The light-field camera is a device that can sample the 4D spatio-angular light field and allows one to refocus the captured image digitally. …
