In this paper, we propose a method for estimating the
optical center of a camera given only a single image with
vignetting. This is accomplished by identifying the center
of the...

Local bundle adjustment (LBA) has recently been introduced
to estimate the geometry of image sequences taken by
a calibrated camera. Its advantage over standard (global)
bundle ...
Normalized Cut is a widely used technique for solving a
variety of problems. Although finding the optimal normalized
cut has proven to be NP-hard, spectral relaxations can
be ap...

We present a system that combines multiple visual navigation techniques to achieve GPS-denied, non-line-of-sight SLAM capability for heterogeneous platforms. Our approach builds o...
Global shape information is an effective top-down complement
to bottom-up figure-ground segmentation as well
as a useful constraint to avoid drift during adaptive tracking.
We p...
