Synthesis of authenticable halftone images with non-luminescent halftones illuminated by a luminescent emissive layer

A method and computing system are proposed for producing an authenticable security device with two sides. The verso side is covered with a luminescent emissive variable intensity layer formed for example by invisible luminescent ink halftones and the recto ...

Cell-based Automatic Deformation Computation by Analyzing Terrestrial LIDAR Point Clouds

Pierre-Yves Gilliéron, Bertrand Merminod, Jing Wu

This paper presents a cell-based approach for computing the deformation of a monitored object by analyzing point cloud data from terrestrial lidar. This approach can automatically generate an informative deformation description (called "deformation map") w ...

Modelling dynamic architectures using Dy-BIP

Joseph Sifakis, Nikolaos Maris

Dynamic architectures in which interactions between components can evolve during execution, are essential for modern computing systems such as web-based systems, reconfigurable middleware, wireless sensor networks and fault-tolerant systems. Currently, we ...

AFFINITY: Efficiently Querying Statistical Measures on Time-Series Data

Karl Aberer, Saket Sathe

Computing statistical measures for large databases of time series is a fundamental primitive for querying and mining time-series data [1–6]. This primitive is gaining importance with the increasing number and rapid growth of time series databases. In this ...

Optically-Clocked Instruction Set Extensions for High Efficiency Embedded Processors

Edoardo Charbon, Ties Jan Henderikus Kluter, Claudio Favi, Christian Mester

We propose a technique to localize computation in Instruction Set Extensions (ISEs) that are clocked at very high speed with respect to the processor. In order to save power, data to and from Custom Instruction Units (CIUs) is synchronized via an optical s ...

Ambient Awareness for the Orchestration of Collaborative Problem Solving

Hamed Seiied Alavi

Classroom orchestration refers to the teacher's (or tutor's) responsibility to identify and manage the evolving learning opportunities and constraints, in real-time. We study the use of computer technology to support this orchestration task in a multi-cons ...

Shortening design time through multiplatform simulations with a portable OpenCL golden-model: the LDPC decoder case

Andreas Peter Burg, Paolo Ienne, Georgios Karakonstantis, David Novo Bruna, Madhura Purnaprajna

Hardware designers and engineers typically need to explore a multi-parametric design space in order to ﬁnd the best conﬁguration for their designs using simulations that can take weeks to months to complete. For example, designers of special purpose chips ...

BRIEF: Computing a Local Binary Descriptor Very Fast

Pascal Fua, Vincent Lepetit, Christoph Strecha, Michael Calonder, Tomasz Piotr Trzcinski, Mustafa Özuysal

Binary descriptors are becoming increasingly popular as a means to compare feature points very fast and while requiring comparatively small amounts of memory. The typical approach to creating them is to first compute floating-point ones, using an algorithm ...
