Stereo Coupled Active Contours
We consider how tracking in stereo may be enhanced by coupling pairs of active contours in different views via affine epipolar geometry and various subsets of planar affine transf...

A New Linear Method for Euclidean Motion/Structure from Three Calibrated Affine Views
We introduce a unified framework for developing matching constraints of multiple affine views and rederive 2-view (affine epipolar geometry) and 3-view (affine image transfer) con...

Projective Rotations Applied to a Pan-Tilt Stereo Head
A non-metric pan-tilt stereo-head consists of a weakly calibrated stereo rig mounted on a pan-tilt mechanism. It is called non-metric since neither the kinematics of the mechanism...

On Plane-Based Camera Calibration: A General Algorithm, Singularities, Applications
We present a general algorithm for plane-based calibration that can deal with arbitrary numbers of views and calibration planes. The algorithm can simultaneously calibrate differe...

Visual Servoing for Automatic and Uncalibrated Needle Placement for Percutaneous Procedures
This paper presents a new approach to image-based guidance of a needle or surgical tool during percutaneous procedures. The method is based on visual servoing. It requires no prio...
