Recursive structure and motion estimation from noisy uncalibrated video sequences
This paper builds on a novel framework of hybrid matching constraints for estimation of structure and recovery of camera focal length and motion, combining the advantages of both ...

Extraction of Outcrop Points from Visual Hulls for Motion Estimation
In this article, we discuss 3D shape reconstruction of an object in a rigid motion with the volume intersection method. When the object moves rigidly, the cameras change their rel...

Discrete camera calibration from the information distance between pixel streams
We consider the problem of estimating the relative orientation of a number of individual photocells -or pixels- that hold fixed relative positions. The photocells measure the inte...

A Rational Function Lens Distortion Model for General Cameras
We introduce a new rational function (RF) model for radial lens distortion in wide-angle and catadioptric lenses, which allows the simultaneous linear estimation of motion and len...

Homography normalization for robust gaze estimation in uncalibrated setups
Homography-based glint-normalization is presented as a novel gaze estimation method for uncalibrated setups. The method is geometrically and empirically demonstrated to be robust ...
