Introduction of cylinder quality measure into Minutia Cylinder-Code based fingerprint matching

Leila Mirmohamadsadeghi, Andrzej Drygajlo, Mohammad Hamed Izadi

Poor data quality is responsible for many or even most matching errors in fingerprint recognition systems. It became obvious that particular effort is needed in adaptation of the state-of-the-art minutiae-based fingerprint matching techniques to real-world ...

Accelerated autofocusing of off-axis holograms using critical sampling

Christian Depeursinge, Muhammed Fatih Toy, Jérôme Parent, Marcel Egli, Stéphane Richard

In this Letter we propose a fast off-axis hologram autofocusing (AF) approach that is based on the redundant data elimination by the critical resampling of the contained complex field. Implementation of the proposed methodology enables the real-time AF wit ...

Quality Assessment of Asymmetric Stereo Pair Formed From Decoded and Synthesized Views

Touradj Ebrahimi, Francesca De Simone, Philippe Hanhart

When a stereo pair is formed from a decoded view and a synthesized view, it is unclear how the overall quality of the stereo pair should be assessed through objective quality metrics. In this paper, this problem is addressed considering a 3D video represen ...

Stochastic simulation of intermittent DSD fields in time

Alexis Berne, Marc Schleiss, Joël Jaffrain

A method for the stochastic simulation of (rain)drop size distributions (DSDs) in space and time using geostatistics is presented. At each pixel, the raindrop size distribution is described by a Gamma distribution with two or three stochastic parameters. T ...

Reducing Uncertainties Regarding Remaining Lives of Structures Using Computer-aided Data Interpretation

Ian Smith, James-Alexandre Goulet, Romain Pasquier

The growing importance of economic and environmental issues associated with the replacement of transportation infrastructure creates a demand for new techniques that are able to predict accurately the behaviour of existing structures. While monitoring stru ...

Spot Identification and Quality Control in Cell-Based Microarrays

Michael Bauer, Blaise Calpe

Cell-based microarrays are being increasingly used as a tool for combinatorial and high throughput screening of cellular microenvironments. Analysis of microarrays requires several steps, including microarray imaging, identification of cell spots, quality ...

Same Queries, Different Data: Can we Predict Query Performance?

Anastasia Ailamaki, Miguel Sérgio De Oliveira Branco, Adrian Daniel Popescu

We consider MapReduce workloads that are produced by analytics applications. In contrast to ad hoc query workloads, analytics applications are comprised of fixed data flows that are run over newly arriving data sets or on different portions of an existing ...

Supervised and unsupervised Web-based language model domain adaptation

Petr Motlicek, John David Scott Dines

Domain language model adaptation consists in re-estimating probabilities of a baseline LM in order to better match the specifics of a given broad topic of interest. To do so, a common strategy is to retrieve adaptation texts from the Web based on a given d ...
