Matching Images to Models - Camera Calibration for 3-D Surface Reconstruction
In a previous paper we described a system which recursively recovers a super-resolved three dimensional surface model from a set of images of the surface. In that paper we assumed ...

Rapid scene modelling, registration and specification for mixed reality systems
Many mixed-reality systems require real-time composition of virtual objects with real video. Such composition requires some description of the virtual and real scene geometries an...

Requirements for Camera Calibration: Must Accuracy Come with a High Price?
While a large number of vision applications rely on the mapping between 3D scenes and their corresponding 2D camera images, the question that occurs to most researchers is what, i...

Towards pose invariant gait reconstruction
Recently, a lot of research has been conducted into the usefulness of gait for identification at a distance. Since the gait of a person is readily identified when extracted from...

Degenerate Cases and Closed-form Solutions for Camera Calibration with One-Dimensional Objects
Camera Calibration with one-dimensional objects is based on an algebraic constraint on the image of the absolute conic. We will give an alternative derivation to this constraint, ...

Collective calibration of active camera groups
Until recently, traditional approaches to the task of camera calibration have relied on the use of accurate grid patterns, or strategically placed targets. Such approaches can pro...

Simultaneous surveillance camera calibration and foot-head homology estimation from human detections
We propose a novel method for automatic camera calibration and foot-head homology estimation by observing persons standing at several positions in the camera field of view. We de...

An LMI Approach for Reliable PTZ Camera Self-Calibration
PTZ (Pan-Tilt-Zoom) cameras are widely used for large-area video surveillance. For many visual tracking and video analysis tasks, an accurate camera calibration is very important....

WOW: wild-open warning for broadcast basketball video based on player trajectory
In basketball games, wild-open means that there is an offensive player not well defended by his/her opponents. The occurrence of wild-open usually implies the existence of a succe...
