Hyperspectral Light Field Stereo Matching

In this paper, we describe how scene depth can be extracted using a hyperspectral light field capture (H-LF) system. Our H-LF system consists of a 5× 6 array of cameras, with each camera sampling a different narrow band in the visible spectrum. There are two parts to extracting scene depth. The first part is our novel cross-spectral pairwise matching technique, which involves a new spectral-inv...

Light Field Assisted Stereo Matching using Depth from Focus and Image-Guided Cost-Volume Filtering

Light field photography advances upon current digital imaging technology by making it possible to adjust focus after capturing a photograph. This capability is enabled by an array of microlenses mounted above the image sensor, allowing the camera to simultaneously capture both light intensity and approximate angle of incidence. The ability to adjust focus after capture makes light field photogr...

Matching Procedures in Field Experiments

To achieve the perfect experimental comparison, the field experimentalist would like to replay history. In this fantasy, a new approach or a new program would be tried. Then, the history rewind button would be pressed to replay events under the traditional or existing program with the same human beings to see whether things turned out differently. No one could argue that the two groups were dis...

Light Field Occlusion Removal

We present a novel method for detecting occlusions and in-painting unknown areas of a light field photograph, based on previous work in obstruction-free photography and light field completion. An initial guess at separating the occluder from the rest of the photograph is computed by aligning backgrounds of the images and using this information to generate an occlusion mask. The masked pixels ar...
