Real-Time Shading With Filtered Importance Sampling

An efficient technique for image-based lighting of objects with spatially varying materials, where BRDF-proportional importance sampling is combined with environment-map filtering to evaluate the illumination integral in real time.

High-Dynamic-Range Image Hallucination

A user-friendly, interactive tool to hallucinate an HDR image from a single LDR input. The technique strives for visually pleasing results, not precise reconstruction, which is usually impossible.

Mesostructure From Specularity Using Coded Illumination

A technique for measuring mesostructure using N controlled light sources but only O(log N) images instead of O(N). This improvement on previous work is achieved by using coded illumination patterns.
