The Bounced Z-buffer for Indirect Visibility
(The Eurographics Association, 2015)
Synthesizing images of animated scenes with indirect illumination and glossy materials at interactive frame rates commonly ignores indirect shadows. In this work we extend a class of indirect lighting algorithms that splat ...
Guiding Image Manipulations using Shape-appearance Subspaces from Co-alignment of Image Collections
(The Eurographics Association and John Wiley & Sons Ltd., 2015)
We propose a system to restrict the manipulation of shape and appearance in an image to a valid subspace which we learn from a collection of exemplar images. To this end, we automatically co-align a collection of images ...
Modeling Luminance Perception at Absolute Threshold
(The Eurographics Association and John Wiley & Sons Ltd., 2015)
When human luminance perception operates close to its absolute threshold, i. e., the lowest perceivable absolute values, appearance changes substantially compared to common photopic or scotopic vision. In particular, most ...
