Feature Generation for Adaptive Gradient-Domain Path Tracing
(The Eurographics Association and John Wiley & Sons Ltd., 2018)
In this paper, we propose a new technique to incorporate recent adaptive rendering approaches built upon local regression theory into a gradient-domain path tracing framework, in order to achieve high-quality rendering ...
Gradient Outlier Removal for Gradient-Domain Path Tracing
(The Eurographics Association and John Wiley & Sons Ltd., 2019)
We present a new outlier removal technique for a gradient-domain path tracing (G-PT) that computes image gradients as well as colors. Our approach rejects gradient outliers whose estimated errors are much higher than those ...
