Title:


    A Compressive Light Field Projection System

Presenter(s):


Entry Number: 02


Description:


    Researchers and experimentalists have strived to bring glasses-free 3D to the big screen. Though light field projection systems are now commercially available, unfortunately they employ dozens of devices. They are costly, energy inefficient, and bulky. We present a compressive approach to light field synthesis for projection devices. We propose a novel, passive screen design inspired by angle-expanding Keplerian telescopes. Combined with high-speed light field projection and nonnegative light field factorization, we demonstrate compressive light field projection with a single device. Our prototype can alternatively display super-resolved and high dynamic range 2D images on a conventional screen.
