In addition, we show how the crex's flexibility enables it to be incorporated in a predictive framework for time-constrained rendering. ...
The computational requirements of full global illumination rendering are such that it is still not possible to achieve high-fidelity graphics of very complex scenes in a reasonable time on a single computer ...

To deal with global and local lighting changes, such as solar flares, the state-of-art illumination invariant photometric costs for RGB-D and stereo SLAM systems are revisited in the context of their monocular ...
The proposed system is extensively evaluated on the synthetic and real-world datasets regarding accuracy, robustness, and processing time, where our approach outperforms systems with other costs and state-of-art ...
Illumination Robust Cost Instead of presenting all real-time capable illuminationinvariant formulations suitable for the joint optimization framework, we merely describe the intensity-based method as a ...
