A novel non-diffractive reconstruction method for digital holographic microscopy
We present a new method for reconstructing digitally recorded off-axis Fresnel holograms. Currently-used reconstruction methods are based on the simulation and propagation of a re...

Generalized Likelihood Ratio-based Face Detection and Extraction of Mouth Features
In this paper we describe a system to reliably localize the position of the speaker’s face and mouth in videophone sequences. A statistical scheme based on a subspace method is p...

Scan order and quantization for 3D-DCT coding
Two types of coders dominate the field of video compression research today: well-established hybrid coders, that are in the core of all MPEG and H.26X standards, and emerging thr...

Mesh size functions for implicit geometries and PDE-based gradient limiting
Mesh generation and mesh enhancement algorithms often require a mesh size function to specify the desired size of the elements. We present algorithms for automatic generation of a...

Robust Extraction of Secret Bits from Minutiae
Abstract. Our goal is to extract consistent bits from the same fingerprint in a noisy environment. Such bits can then be used as a secret key in several cryptographic applications...
