In this paper, we present different solutions for improving spline-based snakes. First, we demonstrate their minimum curvature interpolation property, and use it as an argument to get rid of the explicit smoothness constraint. We also propose a new externa ...
In this paper we present an autonomous mobile robot system allowing for complex collaborative interaction with non-experienced users while giving a pre-programmed tour of a public exposition. For this several modalities of man-machine communication are use ...
Neko: A Single Environment to Simulate and Prototype Distributed Algorithms Peter Urban, Xavier Defago and Andre Schiper Designing, tuning, and analyzing the performance of distributed algorithms and protocols are complex tasks. A major factor that contrib ...
This paper proposes a number of enhancements to UML's Object Constraint Language to improve its usability for specifying operations by pre- and postconditions. In particular, we propose notational shortcuts and semantic modifications to OCL so that it can ...
Most energy saving applications of advanced fenestration systems (solar blinds, novel types of glazing and daylight redirecting devices) require a precise knowledge of their directional light transmission features. These photometric properties can be descr ...
We have designed a series of computer sessions build around ImageJ (a public-domain software for image analysis), as a practical complement to a two-semester course in image processing. The students are challenged with simple practical imaging problems as ...
The paper presents a model for end-user directed access control to services in Internet service centres that, beside the classical Internet services (e.g., e-mail), offer a multitude of new services (e.g., on-line conferencing and auctioning) over the Inte ...
When deploying a secure system based on speaker verification, the limited amount of training data is usually critical. Indeed, the enrollment procedure must be fast and user-friendly. An incremental training of HMM speaker models, based on a MAP (Maximum A ...
This paper presents a survey of developments in de novo phasing methods and instrumentation in protein crystallography that have been carried out over the past 20 years at the French synchrotron radiation facility LURE. This includes progress in detector t ...
Today, there is no standard system for performing maintenance on heterogeneous railway equipments. Maintenance staff needs a standard application capable of diagnosing and monitoring heterogeneous on-board equipments. We propose to build a web-based diagno ...
