This paper describes an efficient method to obtain 3D information from omni images using EPI analysis. Two types of omni cameras are employed to make a spatio-temporal volume, whi...
This paper proposes a new approach to describe the salient contours in cluttered scenes. No need to do the preprocessing, such as edge detection, we directly use a set of random s...
Images taken with wide-angle cameras tend to have severe distortions which pull points towards the optical center: This paper proposes a method for recovering the disrortion param...
A framework for analyzing distortions in non-single viewpoint imaging systems is presented. Such systems possess loci of viewpoints called caustics. In general, perspective (or un...

When studying a 3D polyhedron, it is often easier to cut it open and
atten in on the plane. There are several ways to perform this unfolding. Standard unfoldings which have been u...
