Two Step Variational Method for Subpixel Optical Flow Computation
We develop an algorithm for the super-resolution optical flow computation by combining variational super-resolution and the variational optical flow computation. Our method firs...

Discrete-Time Rigidity-Constrained Optical Flow
An algorithm for optical ow estimation is presented for the case of discrete-time motion of an uncalibrated camera through a rigid world. Unlike traditional optical ow approaches t...

Performance Evaluation of Deflection Routing in Optical IP Packet-Switched Networks
In previous papers [5,6], an optical switch architecture was proposed to handle variable-length packets such as IP datagrams, based on an AWG device to route packets and equipped w...

Revisiting the Brightness Constraint: Probabilistic Formulation and Algorithms
Abstract. In this paper we introduce a principled approach to modeling the image brightness constraint for optical flow algorithms. Using a simple noise model, we derive a probabil...

On Modeling Variations for Face Authentication
In this paper, we present a scheme for face authentication in the presence of variations. To deal with variations, such as facial expressions and registration errors, with which t...
