Post-processing of light fields enables us to extract more information from a scene compared to traditional camera. Plenoptic cameras and camera arrays are two common methods for light-field capture. In fact, it has been long recognized that the two devices are in some ways equivalent. Practically though, light field capture via camera arrays results in poor angular sampling. Similarly, the plenoptic camera often suffers from relatively poor spatial sampling. In simulation, we can easily explore both constraints by simulating two-dimensional view point images and combining them into a four dimensional light field. In this work, we present a formalism for converting between equivalent plenoptic configurations and camera arrays. We use this approach to simulate a simple scene and explore the trade-offs in angular and spatial sampling in light-field capture.

Conference Presentations are recordings of oral presentations given at SPIE conferences and published as part of the proceedings. They include the speaker's narration with video of the slides and animations. Most include full-text papers. Interactive, searchable transcripts and closed captioning are now available for most presentations.
