A Differentiable Wave Optics Model for End-to-End Computational Imaging System Optimization
Chi-Jui Ho, Yash Belhe, Steve Rotenberg +3
End-to-end optimization, which simultaneously optimizes optics and algorithms, has emerged as a powerful data-driven method for computational imaging system design. This method ach…
Volumetrically Consistent 3D Gaussian Rasterization
Chinmay Talegaonkar, Yash Belhe, Ravi Ramamoorthi +1
Recently, 3D Gaussian Splatting (3DGS) has enabled photorealistic view synthesis at high inference speeds. However, its splatting-based rendering model makes several approximations…
Geometry Field Splatting with Gaussian Surfels
Kaiwen Jiang, Venkataram Sivaram, Cheng Peng +1
Geometric reconstruction of opaque surfaces from images is a longstanding challenge in computer vision, with renewed interest from volumetric view synthesis algorithms using radian…
Efficient Scene Appearance Aggregation for Level-of-Detail Rendering
Yang Zhou, Tao Huang, Ravi Ramamoorthi +2
Creating an appearance-preserving level-of-detail (LoD) representation for arbitrary 3D scenes is a challenging problem. The appearance of a scene is an intricate combination of bo…
Residual path integrals for re-rendering
Bing Xu, Tzu-Mao Li, Iliyan Georgiev +2
Conventional rendering techniques are primarily designed and optimized for single-frame rendering. In practical applications, such as scene editing and animation rendering, users f…
A Construct-Optimize Approach to Sparse View Synthesis without Camera Pose
Kaiwen Jiang, Yang Fu, Mukund Varma T +4
Novel view synthesis from a sparse set of input images is a challenging problem of great practical interest, especially when camera poses are absent or inaccurate. Direct optimizat…
