Object-Centric Neural Scene Rendering


<OSF> Object-centric neural scene rendering

编者按

  • 相比于组成式,其实更关注多物体之间的 Lighting
  • 物体 pose 都是真值
  • 相比于 GIRAFFE,把多物体的光照、反射等处理地很好了;GIRAFFE 是用 neural rendering 逃避了显式地建模光照和多物体透射反射,这篇文章直面难题,类似 Neural Reflectance Field
  • 看上去物体位置、id 都是真值,重点主要是建模好多物体的光照

Motivation

  • https://longtimenohack.com/posts/paper_reading/2021_guo_osf/image-20201221161533104.png
  • OSF(object-centric neural scattering functions) models per-object light transport
  • modeling dynamic scene:物体在移动/有无,光源在移动

Overview

  • 数据集
    • furniture-single
    • furniture-random 25 个动态的场景,每个包含多个物体的随机 layout
    • furniture-realisitc
