    • Variance Analysis of Multi-sample and One-sample Multiple Importance Sampling 

      Sbert, Mateu; Havran, Vlastimil; Szirmay-Kalos, Laszlo (The Eurographics Association and John Wiley & Sons Ltd., 2016)
      We reexamine in this paper the variance for the Multiple Importance Sampling (MIS) estimator for multi-sample and onesample model. As a result of our analysis we can obtain the optimal estimator for the multi-sample model ...

    • Visual Contrast Sensitivity and Discrimination for 3D Meshes and their Applications 

      Nader, Georges; Wang, Kai; Hétroy-Wheeler, Franck; Dupont, Florent (The Eurographics Association and John Wiley & Sons Ltd., 2016)
      In this paper, we first introduce an algorithm for estimating the visual contrast on a 3D mesh. We then perform a series of psychophysical experiments to study the effects of contrast sensitivity and contrast discrimination ...
