Image-guided Surgical Microscope

We present an image-guided microscope system using augmented reality image overlays added onto one of the views of the operating microscope. With this system, segmented objects, outlines of risk regions or access pathways, previously extracted from preoper ...

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

Jean-Philippe Thiran, Pierre Vandergheynst, Xavier Bresson

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 ...

Unsupervised Location-Based Segmentation of Multi-Party Speech

Jean-Marc Odobez, Guillaume Lathoud

Accurate detection and segmentation of spontaneous multi-party speech is crucial for a variety of applications, including speech acquisition and recognition, as well as higher-level event recognition. However, the highly sporadic nature of spontaneous spee ...

Dynamically Reducing Pressure on the Physical Register File through Simple Register Sharing (Best Paper Award)

Using register renaming and physical registers, modern microprocessors eliminate false data dependences from reuse of the instruction set defined registers (logical registers). High performance processors that have longer pipelines and a greater capacity t ...

Interaction between High-Level and Low-Level Image Analysis for Semantic Video Object Extraction

Touradj Ebrahimi, Andrea Cavallaro

The task of extracting a semantic video object is split into two subproblems, namely, object segmentation and region segmentation. Object segmentation relies on a priori assumptions, whereas region segmentation is data-driven and can be solved in an automa ...

Shared Memory vs Message Passing

Rachid Guerraoui

his paper determines the computational strenght of the shared memory abstraction (a register) emulated over a message passing system, and compares it with fundamental message passing abstractions like consensus and various forms of reliable broadcast. We i ...

A Priori Information in Image Segmentation: Energy Functional based on Shape Statistical Model and Image Information

Jean-Philippe Thiran, Pierre Vandergheynst, Xavier Bresson

In this paper, we propose an energy functional to segment objects whose global shape is ...

Objective evaluation of segmentation quality using spatio-temporal context

Touradj Ebrahimi, Elisa Drelie Gelasca

In this paper, we propose an automatic method for the objective evaluation of segmentation results. The method is based on computing the deviation of the segmentation results from a reference segmentation. The discrepancy between two results is weighted ba ...

MESH: Measuring Errors between Surfaces using the Hausdorff distance

Touradj Ebrahimi, Nicolas Aspert

This paper proposes an efficient method to estimate the distance between discrete 3D surfaces represented by triangular 3D meshes. The metric used is based on an approximation of the Hausdorff distance, which has been appropriately implemented in order to ...

Influence of a Large Image Watermarking Scheme Parallelization on Possible Attacks

Touradj Ebrahimi, Oscar Divorra Escoda

Digital data representation provides an efficient and fast way to access to information and to exchange it. In many situations though ownership or copyright protection mechanisms are desired. For still images and video, one possible way to achieve this is ...
