SUMMARY:Sample Matching for Joint Extinction Gradient Estimation in Differ
 entiable Volume Rendering
DESCRIPTION:Ruihan Yu (The University of Tokyo, Tsinghua University); Yu-C
 hen Wang (University of California Irvine); Jingwang Ling (University of I
 llinois Urbana-Champaign); Feng Xu (Tsinghua University); and Shuang Zhao 
 (University of Illinois Urbana-Champaign)\n\nWe propose sample matching, a
  variance reduction principle for differentiable volume rendering. By join
 tly estimating scattering and transmittance gradient components at shared 
 sample positions, our method reduces gradient variance by up to 80%, signi
 ficantly improving convergence speed and reconstruction quality in volumet
 ric inverse rendering.\n\nInterest Area: Research & Education\n\nKeyword: 
 Lighting, Modeling, Rendering\n\nRegistration Category: Full Conference Su
 pporter, Full Conference\n\nSession Chair: David Hahn (Technische Universi
 tät Wien (TU Wien))\n\n
