Learning to Synthesize a 4D RGBD Light Field from a Single Image [article]

Pratul P. Srinivasan, Tongzhou Wang, Ashwin Sreelal, Ravi Ramamoorthi, Ren Ng
2017 arXiv   pre-print
We present a machine learning algorithm that takes as input a 2D RGB image and synthesizes a 4D RGBD light field (color and depth of the scene in each ray direction).  ...  Our algorithm builds on recent view synthesis methods, but is unique in predicting RGBD for each light field ray and improving unsupervised single image depth estimation by enforcing consistency of ray  ...  Computing, and a generous GPU donation from NVIDIA.  ...

Image registration for image-based rendering

A.M.K. Siu, R.W.H. Lau
2005 IEEE Transactions on Image Processing  
Image-based rendering (IBR) has received much attention in recent years for its ability to synthesize photo-realistic novel views.  ...  This results in a high spatial sampling rate, making IBR impractical for use in scalable walkthrough environments.Our primary objective of this project is to develop an image registration technique that  ...  ACKNOWLEDGMENT The authors would like to thank the anonymous reviewers for their helpful and constructive comments on this paper. They would also like to thank A. Wan for some of the discussions.  ...
