Kalman Filtering for Robust Identification of Face Images with Varying Expressions and Lighting Conditions
We propose a novel algorithm for the identification of faces from image samples. The algorithm uses the Kalman filter to identify significant face features. We employ the Kalmanfa...

Differential privacy and robust statistics
We show by means of several examples that robust statistical estimators present an excellent starting point for differentially private estimators. Our algorithms use a new paradig...

A robust and tractable contact model for dynamic robotic simulation
Existing contact modeling in rigid body simulation is inadequate for robotics: no algorithms guarantee both convergence and nonpenetration at multiple contact points in the presen...

Robust region-based background subtraction and shadow removing using color and gradient information
In this paper, a novel algorithm for foreground detection and shadow removal is presented. The proposed method employs a region-based approach by processing two foregrounds result...

Flipping to Robustly Delete a Vertex in a Delaunay Tetrahedralization
We discuss the deletion of a single vertex in a Delaunay tetrahedralization (DT). While some theoretical solutions exist for this problem, the many degeneracies in three dimensions...
