This is a set of tools for working with light field (aka plenoptic) imagery in Matlab. This version of the toolbox is focused on processing images from the Lytro plenoptic camera. Features include decoding, colour correction and visualization of light field images. New in version 0.2 are camera calibration, image rectification, and convenience functions for managing multiple light fields and multiple cameras. Future releases will support additional input formats and depth and volumetric filtering for improved rendering quality.
Download the sample light field pack at http://www-personal.acfr.usyd.edu.au/ddan1654/LFSamplePack1-r2.zip. This revision of the sample pack introduces a folder structure facilitating the use of multiple cameras. A small sample calibration is also available at http://www-personal.acfr.usyd.edu.au/ddan1654/PlenCalSmallExample.zip, and further calibration datasets can be found at http://marine.acfr.usyd.edu.au/index.php/Plenoptic .
The image decoding, calibration and rectification process is described in:
