The KGBR Viewpoint-Lighting Ambiguity and its Resolution by Generic Constraints
We describe a novel viewpoint-lighting ambiguity which we call the KGBR. This ambiguity assumes orthographic projection or an affine camera, and uses Lambertian reflectance functi...

Can Two Specular Pixels Calibrate Photometric Stereo?
Lambertian photometric stereo with unknown light source parameters is ambiguous. Provided that the object imaged constitutes a surface, the ambiguity is represented by the group o...

EKF pose estimation: How many filters and cameras to use?
The Extended Kalman Filter (EKF) is suitable for real-time pose estimation due its low computational demand and ability to handle the nonlinear perspective camera model. There are...
