Stable Structure from Motion for Unordered Image Collections
We present a non-incremental approach to structure from motion. Our solution is based on robustly computing global rotations from relative geometries and feeding these into the kno...

Individual Contour Extraction for Robust Wide Area Target Tracking in Visual Sensor Networks
In this paper, we propose an approach to collaboratively track motion of a moving target in a wide area utilizing camera-equipped visual sensor networks, which are expected to pla...

Camera Calibration with Two Arbitrary Coaxial Circles
Abstract. We present an approach for camera calibration from the image of at least two circles arranged in a coaxial way. Such a geometric configuration arises in static scenes of ...

Qualitative Visual Interpretation of 3d Hand Gestures Using Motion Parallax
We present an efficient and geometrically intuitive algorithm to reliably interpret the image velocities of moving objects in 3D. It is well known that in a small neighbourhood th...
