Investigation of plenoptic imaging systems: a wave optics approach
… the light. A new generation of imaging devices, plenoptic systems, use an array of micro lenses to codify the light coming from an object into a four dimensional function called the light field. The final image is then obtained after post processing computations on the light field. In this work …

Computational crowd camera : enabling remote-vision via sparse collective plenoptic sampling
In this thesis, I present a near real-time algorithm for interactively exploring a collectively captured moment without explicit 3D reconstruction. This system favors immediacy and local coherency to global consistency. It is common to represent photos as vertices of a weighted graph, where edge …

Three-Dimensional Fluid Flow Measurement Techniques with Applications to Biological Flows
The accuracy of plenoptic and tomographic particle image velocimetry (PIV) experimental methods is measured by simulating three-dimensional flows and measuring the errors in the estimated versus true velocity fields. Parametric studies investigate the accuracy of these methods by simulating a range …

Path from Photorealism to Perceptual Realism
… representation, and reproduction of the plenoptic function of a 3D scene. Finally, we demonstrate that taking advantage of the limits and mechanisms of the human visual system can significantly improve this pipeline. Specifically, we present three approaches to push the quality of virtual …
