Image-based Participating Media
(The Eurographics Association, 2008)
Light transport inside participating media, like fog or water, involves complex interaction phenomena, which make traditional 3D rendering approaches challenging and computationally expensive. To circumvent this, we propose ...
Light Source Detection in Photographs
(The Eurographics Association, 2009)
Common tasks related to image processing or augmented reality include rendering new objects into existing images, or matching objects with unknown illumination. To facilitate such algorithms, it is often necessary to infer ...
Where are the Lights? Measuring the Accuracy of Human Vision
(The Eurographics Association, 2009)
In real life, light sources are frequently not present in our view field. However human vision is able to infer the illumination just by observing its effect on visible objects (serving as lightprobes) or, inverting the ...
