    • Gradient-Domain Photon Density Estimation 

      Hua, Binh-Son; Gruson, Adrien; Nowrouzezahrai, Derek; Hachisuka, Toshiya (The Eurographics Association and John Wiley & Sons Ltd., 2017)
      The most common solutions to the light transport problem rely on either Monte Carlo (MC) integration or density estimation methods, such as uni- & bi-directional path tracing or photon mapping. Recent gradient-domain ...
    • Gradient-Domain Vertex Connection and Merging 

      Sun, Weilun; Sun, Xin; Carr, Nathan A.; Nowrouzezahrai, Derek; Ramamoorthi, Ravi (The Eurographics Association, 2017)
      Recently, gradient-domain rendering techniques have shown great promise in reducing Monte Carlo noise and improving overall rendering efficiency. However, all existing gradient-domain methods are built exclusively on top ...
    • Gradient-Preserving Color Transfer 

      Xiao, Xuezhong; Ma, Lizhuang (The Eurographics Association and Blackwell Publishing Ltd, 2009)
      Color transfer is an image processing technique which can produce a new image combining one source image s contents with another image s color style. While being able to produce convincing results, however, Reinhard et al. ...
