Unsupervised Segmentation of Poisson Data
This paper describes a new approach to the analysis of Poisson point processes, in time (1D) or space (2D), which is based on the minimum description length (MDL) framework. Speci...

Self-Calibration of Zooming Cameras Observing an Unknown Planar Structure
In this paper, we propose a new self-calibration technique for cameras with changing zoom observing only a planar structure. The method does not need any metric or topologic knowl...
