Image-based rendering (IBR) systems enable virtual walkthroughs
of photorealistic environments by warping and combining
reference images to novel viewpoints under interactive user
control. A significant challenge in such systems is to
automatically compute image correspondences that enable
accurate image warping.
In this paper, we describe a new algorithm for computing a
globally consistent set of image feature correspondences across a
wide range of viewpoints suitable for IBR walkthroughs. We first
detect point features in a dense set of omnidirectional images
captured on an eye-height plane. Then, we track these features
from image to image, identifying potential correspondences when
