The article presents the concepts and the tools involved in the interactive design of artistic screens. The screen elements are derived from a small set of analytical contours provided by the screen designer. We present the requirements that these contours ...
We present an algorithm for tracking video object which is based on an hybrid strategy. This strategy uses both object and region information to solve the correspondence problem. Low level descriptors are exploited to track objects regions and to cope wit ...
Equil. aspects in biotechnol. and thermodn. as the main theory underlying them have thus far received relatively little attention. As a consequence, design and development of biotechnogical processes is still carried out today in an relatively empirical wa ...
In this paper, we propose a new variational model to segment an object belonging to a given shape space using the active contour method, a geometric shape prior and the Mumford-Shah functional. The core of our model is an energy functional composed by thre ...
Standardization can be performed only in a field in which the knowledge of the physical phenomena and of the behavior of the given installation is sufficiently known. The role of the universities is to perform research in order to clarify such these points ...
Radiotherapy treatment planning requires exact delineation of tumors in acquired images. Further, motion and deformation of a tumor due to respiratory movements must be known in order to better target and dose the treatment radiation. Here we present and i ...
Replication is a key mechanism for developing fault-tolerant and highly available applications. In this paper, we present a replication framework for replicating CORBA objects, that combines the active and passive replication techniques. We show how we hav ...
Confidential information contained in the transactional data created in mobile communication systems is not very well protected. We present an approach to protect entire objects against manipulation and disclosure, which allows to retain some control over ...
The increased interest in protocols that provide a total order on message delivery has led to several different definitions of total order. In this paper we investigate these different definitions and propose a hierarchy that helps to better understand the ...
In this paper, we propose a variational model to segment an object belonging to a given scale space using the active contour method, a geometric shape prior and the Mumford-Shah functional. We define an energy functional composed by three complementary ter ...
