Generalized Image Acquisition and Analysis

State of the Art in Computational Fabrication and Display of Material Appearance.

After decades of research on digital representations of material and object appearance, computer graphics has more recently turned to the problem of creating physical artifacts with controllable appearance characteristics. While this work has mostly progressed in two parallel streams – display technologies as well as novel fabrication processes – we believe there is a large overlap and the potential for synergies between these two approaches. In this report, we summarize research efforts from the worlds of fabrication display, and categorize the different approaches into a common taxonomy. We believe that this report can serve as a basis for systematic exploration of the design space in future research.



Software Update

The MATLAB Color Calibration Toolbox v2.1 (minor update) has been updated. No new functionalities this time; added error tolerance against missing packages.

Slides are online here.


GIAnA associated with the Laboratoire Photonique, Numerique et Nanosciences (LP2N)

We will create a computational optics group at the LP2N.


GIAnA joined INRIA

Generalized Image Acquisition and Analysis moved to Bordeaux to join the manao team.


Emmy-Noether Group

Generalized Image Acquisition and Analysis is now supported by an Emmy-Noether grant.


Software Update

The MATLAB Color Calibration Toolbox has been updated and is now supporting radiometric response curve estimation.


In the press

Johannes Kepler University Linz is reporting about our E-Lecture on Computational Photography last summer term. It was the first remote-only lecture for JKU. Eleven students attended the course at JKU.


In the press

Our work on dynamically displaying BRDFs is going to be featured in the September issue of 3D World, a magazine for 3D artists, covering SIGGRAPH's Emerging Technologies where we will demo our work. Matthias Hullin is quoted as "I don't expect a BRDF display to become available in the next 20 years. The principle on which the Nintendo 3DS is based was patented back in 1913!" -->
