The projective equation of a circle and its application in camera calibration
In this article, we present the projective equation of a circle in a perspective view, which naturally encodes such important geometric entities as the projected circle center, th...

Real-time tracking of complex structures with on-line camera calibration
This paper presents a novel three-dimensional model-based tracking system which has been incorporated into a visual servoing system. The tracking system combines modern graphical ...

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...

Q-SIFT: Efficient feature descriptors for distributed camera calibration
We consider camera self-calibration, i.e. the estimation of parameters for camera sensors, in the setting of a visual sensor network where the sensors are distributed and energy-c...

Obtaining 3-D shape from Silhouette Informations Interpolated by Photometric Stereo
The idea of photometric stereo is to serially vary the direction of incident illumination on the state of the holded view point, but it can locally reconstruct only the front surf...
