Plenoptic Processing and Lightfield Microscopy

.The goal is to understand the nature of the data in light-field systems particularly in terms of structure and coherence. Specifically, we study the extraction of coherent regions and occlusion boundaries which is an important issue in numerous plenoptic base processing applications. We focus in particular on light field microscopy for neuroscience.
