Recovering Light Directions and Camera Poses from a Single Sphere
This paper introduces a novel method for recovering both the light directions and camera poses from a single sphere. Traditional methods for estimating light directions using spher...

Navigation using a spherical camera
A novel group theoretical method is proposed for autonomous navigation based on a spherical image camera. The environment of a robot is captured on a sphere. The three dimensional...

New decoupled visual servoing scheme based on invariants from projection onto a sphere
— In this paper a new decoupled imaged-based control scheme is proposed from projection onto a unit sphere. This control scheme is based on moment invariants to 3D rotational mot...

Spherical image-based visual servo and structure estimation
— This paper presents a formulation of image-based visual servoing (IBVS) for a spherical camera where coordinates are parameterized in terms of colatitude and longitude: IBVSSph...

Difference Sphere: An Approach to Near Light Source Estimation
We present a novel approach for estimating light sources from a single image of a scene that is illuminated by major near point light sources, a few directional light sources and ...
