SUMMARY:Differentiable rendering using RGBXY derivatives and optimal trans
 port
DESCRIPTION:Technical Communications, Technical Papers\n\nDifferentiable r
 endering using RGBXY derivatives and optimal transport\n\nXing, Luan, Yan,
  Hu, Qian...\n\nWe present a novel differentiable rendering framework that
  is reformulated from the Lagrangian view. Inspired by fluid simulation, t
 raditional differentiable rendering approach can be viewed as the Eulerian
  method due to the fact that image derivatives are computed locally on a f
 ixed grid of screen-space pixels. In contrast, our method tackles this pro
 blem from the Lagrangian viewpoint, where pixels are considered as fluid p
 articles that are movable across the image plane locations, capturing glob
 al and long-range object motions efficiently. We guide the underlying geom
 etry point at each pixel through robust correspondence finding and track h
 ow they change with respect to the optimizable scene parameters. As the ef
 ficacy of our technique hinges with the quality of the searched correspond
 ence, we present a study of different distance calculation metrics includi
 ng bipartite graph matching, flow estimation and optimal transport. Furthe
 r, we evaluate the effectiveness of our proposed framework on various inve
 rse rendering applications and demonstrate superior convergence behavior c
 ompared to state-of-the-art baselines.\n\nRegistration Category: FULL ACCE
