    • Gradient Outlier Removal for Gradient-Domain Path Tracing 

      Ha, Saerom; Oh, Sojin; Back, Jonghee; Yoon, Sung-Eui; Moon, Bochang (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 ...
