Abstract

We present a novel use of commodity graphics hardware that effectively combines a plane-sweeping algorithm [Collins 1996] and view synthesis in a single step for real-time, on-line 3D view synthesis. Unlike typical stereo algorithms that use image-based metrics to estimate depths, we focus on using image-based metrics to directly estimate images. Using real-time imagery from a few calibrated cameras, our method can generate new images from nearby viewpoints, without any prior geometric information or requiring any user interaction, in real time and on line.
