Light Field Toolbox 0.4 adds Linear Depth/Focus and Denoising Filters

Light Field Toolbox 0.4 adds Linear Depth/Focus and Denoising Filters If you’ve been following the development of the Light Field Toolbox for Matlab, please note that the author has released an update with new features: Light Field Toolbox v0.4 builds upon the previous version and adds linear depth/focus and denoising filters for light field pictures.

For more technical information regarding these filters and their use, please refer to the following upcoming publication: D.G. Dansereau, O. Pizarro, and S. B. Williams, “Linear Volumetric Focus for Light Field Cameras,” to appear in ACM Transactions on Graphics (TOG), vol. 34, no. 2, 2015.

Lytro in Linux: Lyli Aims to Become Open-Source Alternative to Lytro Desktop [Updated]

Lytro in Linux: Lyli Aims to Become Open-Source Alternative to Lytro Desktop As exciting as the technology is, not everybody has access to Lytro’s light field tech due to their computer platform of choice. For the obvious reason of limited resources and man-hours in a small startup, it took the company an additional five months from the release of their first-generation camera to expand from Mac-only software to Windows, back in 2012. Linux, on the other hand, continues to be “not currently on Lytro’s roadmap“.

Now, in our forums section, Lukáš Jirkovský has announced his own Linux-compatible, open-source alternative to Lytro Desktop, called Lyli.

Lyli is a work in progress, but the developer has big plans for his application: Continue reading

Light Field Toolbox 0.3: Compatibility with Lytro Illum and Lytro Desktop 4 and more

Light Field Toolbox 0.3: Compatibility with Lytro Illum and Lytro Desktop 4 and more Donald Danserau’s LightField Toolbox is a collection of software tools to process light field data in Matlab. The software package has recently received an update to version 0.3., which adds compatibility for files created with Lytro Illum and Lytro Desktop 4.
LightField Toolbox can now directly open Lytro LFP files, and new functions allow reading of gantry-style light fields.

Lytro Meltdown: Illum Support in Not Before Spring 2015

Lytro Compatible Viewer: Parallax Shift with processed image stack As many of our readers already know, the Lytro Meltdown contains lots of inside information and series of software tools to explore RAW and processed Lytro pictures. Programmes like the Lytro Compatible Library, Lytro Compatible Viewer and Lytro Compatible Communicator are compatible with the first-generation Lytro camera, but only some features currently work with the Lytro Illum‘s pictures.

Now, author Jan Kučera answers the question when his software will receive Illum compatibility – which unfortunately won’t be in the very near future: Continue reading

Fraunhofer DCA Presents Light-Field Plugin for Avid Media Composer

Light field technology produces a completely new, and fundamentally richer, set of data. With all of the advantages of this technology, the obvious downside is that there isn’t yet much software out there to process this data.
Now, the Fraunhofer Digital Cinema Alliance has presented a light-field plug-in for the popular video post processing application Avid Media Composer.

Fraunhofer DCA Presents Light-Field Plugin for Avid Media Composer (picture: Fraunhofer IIS) According to their press release, the software plugin is able to create high-resolution depth maps, change focus, move perspective or add 3D effects and camera movement. The output can then be used to generate footage for 2D, 3D or multi-view displays — and all of that by using existing video software. A licensing model is available for professional users interested in working with light-field video.
