A Variational Model for Object Segmentation Using Boundary Information and Shape Prior Driven by the Mumford-Shah Functional

Jean-Philippe Thiran, Pierre Vandergheynst, Xavier Bresson

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 ...

High Resolution Interference Microscopy: A Tool for Probing Optical Waves in the Far-Field on a Nanometric Length Scale

Hans Peter Herzig, René Dändliker, Toralf Scharf, Iwan Märki

High Resolution Interference Microscopy (HRIM) is a technique that allows the characterization of amplitude and phase of electromagnetic wave-fields in the far-field with a spatial accuracy that corresponds to a few nanometers in the object plane. Emphasis ...

Autonomous Self-assembly in a Swarm-bot

Francesco Mondada, Michael Bonani, Roderich Gross

Multi-robot systems have been studied in tasks that require the robots to be physically linked. In such a configuration, a group of robots may navigate a terrain that proves too difficult for a single robot. On the contrary, many collective tasks can be ac ...

Animal dispersal modelling: handling landscape features and related animal choices

Séverine Vuilleumier Varisco, Richard Metzger

Animal dispersal in a fragmented landscape depends on the complex interaction between landscape structure and animal behavior. To better understand how individuals disperse, it is important to explicitly represent the properties of organisms and the landsc ...

Computing with Reads and Writes in the Absence of Step Contention

Rachid Guerraoui

This paper studies implementations of concurrent objects that exploit the absence of step contention. These implementations use only reads and writes when a process is running solo. The other processes might be busy with other objects, swapped-out, failed, ...

Pattern Recognition from One Example by Chopping

François Fleuret

We investigate the learning of the appearance of an object from a single image of it. Instead of using a large number of pictures of an object to be recognized, we use pictures of other objects to learn invariance to noise and variations in pose and illumi ...

Tracking Video Objects in Cluttered Background

Touradj Ebrahimi

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 ...

Semantics-based representation of virtual environments

Daniel Thalmann, Frédéric Vexo

In this paper we present an object representation based on the semantics and functionality of interactive digital items - virtual objects - within a virtual environment (VE). We consider every object participating in a VE application not only as a 3D shape ...

An object-oriented model for adaptive high-performance computing on the computational GRID

Tuan Anh Nguyen

The dissertation presents a new parallel programming paradigm for developing high performance (HPC) applications on the Grid. We address the question "How to tailor HPC applications to the Grid?" where the heterogeneity and the large scale of resources are ...

Acquiring, structuring shapes and annotating them with semantics to improve design activities

Daniel Thalmann, Frédéric Vexo

Shapes incorporate geometry as well as semantics and can be defined in 2D, 3D or higher dimensions. Geometric models can be structured in such a way that they can provide a relevant framework to insert semantic information or view dependent information abo ...
