BMAT: An open-source BIDS managing and analysis tool

Meritxell Bach Cuadra, Benoît Macq, Francesco La Rosa, Maxence Charles F Wynen

Magnetic Resonance Imaging (MRI) is an established technique to study in vivo neurological disorders such as Multiple Sclerosis (MS). To avoid errors on MRI data organization and automated processing, a standard called Brain Imaging Data Structure (BIDS) h ...

A Signal Peak Separation Index for axisymmetric B-tensor encoding

Jean-Philippe Thiran, Benoît Macq, Gabriel Girard, Gaëtan Olivier D Rensonnet, Jonathan Rafael Patino Lopez, Marco Pizzolato

Diffusion-weighted MRI (DW-MRI) has recently seen a rising interest in planar, spherical and general B-tensor encodings. Some of these sequences have aided traditional linear encoding in the estimation of white matter microstructural features, generally by ...

Extra-axonal restricted diffusion as an in-vivo marker of reactive microglia

Benoît Macq, Gaëtan Olivier D Rensonnet, Anne des Rieux

Reactive microgliosis is an important pathological component of neuroinflammation and has been implicated in a wide range of brain diseases including brain tumors, multiple sclerosis, Parkinson's disease, Alzheimer's disease, and schizophrenia. Mapping rea ...

Towards microstructure fingerprinting: Estimation of tissue properties from a dictionary of Monte Carlo diffusion MRI simulations

Jean-Philippe Thiran, Benoît Macq, Gabriel Girard, Gaëtan Olivier D Rensonnet

Many closed-form analytical models have been proposed to relate the diffusion-weighted magnetic resonance imaging (DW-MRI) signal to microstructural features of white matter tissues. These models generally make assumptions about the tissue and the diffusio ...

Overview of the JPEG XS core coding system subjective evaluations

Touradj Ebrahimi, Benoît Macq, Irene Viola, Jakub Pospisil

The JPEG committee (Joint Photographic Experts Group, formally known as ISO/IEC SC29 WG1) is currently in the process of standardizing JPEG XS, a new interoperable solution for low-latency, lightweight and visually lossless compression of image and video. ...

Scalable Feature Extraction for Coarse-to-Fine JPEG2000 Image Classification

Pierre Vandergheynst, Benoît Macq, Christophe De Vleeschouwer

In this paper, we address the issues of analyzing and classifying JPEG 2000 code-streams. An original representation, called integral volume, is first proposed to compute local image features progressively from the compressed code-stream, on any spatial im ...

Dense Deformation Field Estimation for Atlas-based Segmentation of Pathological MR Brain Images

Valérie Duay, Jean-Philippe Thiran, Meritxell Bach Cuadra, Benoît Macq, Mathieu De Craene

Atlas registration is a recognized paradigm for the automatic segmentation of normal MR brain images. Unfortunately, atlas-based segmentation has been of limited use in presence of large space-occupying lesions. In fact, brain deformations induced by such ...

Coarse-to-fine textures retrieval in the JPEG 2000 compressed domain for fast browsing of large image databases

Pierre Vandergheynst, Benoît Macq, Christophe De Vleeschouwer

In many applications, the amount and resolution of digital images have significantly increased over the past few years. For this reason, there is a growing interest for techniques allowing to efficiently browse and seek information inside such huge data sp ...
