Parallax rectification for spectrally-coded plenoptic cameras

Spectrally-coded plenoptic cameras have been developed for single-snapshot spectral imaging. Whereas reconstruction of spectral images from plenoptic sensor data has been studied in the past, rectification of those images according to a depth distribution in the scene has not been investigated. In this paper we describe a spectral parallax rectification algorithm for plenoptic cameras. The algorithm is designed to handle flexible filter partitions in the aperture and the small baselines inherent to plenoptic cameras. We demonstrate the algorithm´s performance using checkerboard and captured scene data.
