A Spatio-temporal Role-Based Access Control Model
With the growing advancement of pervasive computing technologies, we are moving towards an era where spatio-temporal information will be necessary for access control. The use of su...

Uncertainty optimization for robust dynamic optical flow estimation
We develop an optical flow estimation framework that focuses on motion estimation over time formulated in a Dynamic Bayesian Network. It realizes a spatiotemporal integration of ...

A Description Logic of Change
We combine the modal logic S5 with the description logic (DL) ALCQI. In this way, we obtain a multi-dimensional DL, S5ALCQI, whose purpose is reasoning about change. S5ALCQI is ca...

Unsupervised clustering of continuous trajectories of kinematic trees with SOM-SD
We explore the capability of the Self Organizing Map for structured data (SOM-SD) to compress continuous time data recorded from a kinematic tree, which can represent a robot or an...
