LightField Toolbox: Lytro Image Processing in Matlab

LightField Toolbox: Lytro Image Processing in Matlab Processing Lytro LightField Pictures is generally done within the free, official Lytro Desktop Software. If you want more control over your LightField results, though, there are a few tools available to do just that. (Note that the Desktop Software is still needed to transfer the pictures from the camera.)

The newest addition to the list of openly available LightField tools is LightField Toolbox v0.1 for Matlab, by Donald G. Dansereau.
It its initial release, it is limited to basic features such as loading, decoding, colour correction and visualization (including a basic perspective shift effect) of Lytro light field images. But there’s more to come!

This version of the toolbox and documentation are focused on Lytro imagery. Adapting this to other cameras should be straightforward. Future releases will support additional input formats, camera calibration, image rectification, and depth and volumetric filtering for improved rendering quality.

tap2focus: Interactive Refocus for your iPhone

tap2focus: Interactive Refocus for your iPhone Manufacturers are racing towards creating the first light field enabled smartphone, and the first ones are expected to be released early next year.
If you have an iPhone, you don’t have to wait until then to create pictures with interactive refocus: App developer Caal Studio took the same technological short-cut that MEMS technology uses for image refocus, and merges several images focused at different depths to create a Lytro-like effect.

Their new iOS App tap2focus allows you to take multiple pictures at different focal lengths by tapping on the live camera preview, while holding the iPhone or iPod Touch as stationary as possible.
The app then combines these images into an interactive image, which can be viewed and refocused on the device itself and shared to facebook, twitter or via email.
