Projects & Research Interests

My personal research interests are in image informatics (in particular "bioimage informatics" and digital pathology), machine learning, computer vision, big data, open science.

Image informatics

In 2010, I initiated the CYTOMINE research project which lead to the development of the CYTOMINE open-source software platform (Marée et al., Bioinformatics 2016), a "Google Maps"-like rich internet application for remote visualization, annotation and automated analysis of high-resolution, multi-gigapixels images. It is now used in various domains (including digital pathology) by various entities around the world. In addition to ongoing research at University of Liège, we created Cytomine SCRL FS, a not-for-profit cooperative company to provide services on top of the open-source software.

More recently we are focusing on designing methods for multispectral/multimodal data sources, benchmarking, and user behavior analytics (see CYTOMINE research project page).

Machine/Deep learning for computer vision

This research is about the design of generic methods for automatic image classification, retrieval, interest point detection, and semantic segmentation. Indeed, as potential applications of image recognition technologies are multidinous, we seek to develop general-purpose methods for the recognition of various types of images that share some visual regularities, without relying on too strong assumptions about patterns to recognize and acquisition conditions, and without having to rely on domain experts to design specific features.

This book chapter (2013) summarizes our work where we combine ensemble of randomized decision trees with random extraction of subwindows (square patches) described by their raw pixel values. We are conducting large-scale empirical studies on several recognition datasets to better identify influential design choices and draw general guidelines for future use, and to further increase robustness of our approaches. See e.g. our image classification paper in Pattern Recognition Letters (2016) or our interest point detection paper in Nature Scientific Reports (2018). More recently, we are trying to combine ideas from tree-based methods with deep learning methods, see e.g. our CVPR-CVMI paper (2018).

Bioinformatics

Between January 2005 and October 2014, I was the GIGA Bioinformatics platform manager (scientific head: Prof. L. Wehenkel). In close collaboration with the Bioinformatics and Modeling research unit, this platform offers software development and data analysis services to academic (within the GIGA research center and beyond) as well as to industrial researchers. Its services include classification of biological/biomedical data (SELDI mass spectra, microarrays, clinical databases, ...) obtained from various medical instrumentation based on machine learning methods. This activity lead to co-authorship of several journal papers (in Journal of Immunology, Proteomics, Annals of the rheumatic diseases, ...) in various application domains (inflammatory diseases, cancer, ...).

Open science

I'm very much in favor of basic principles of open science (open access, open data, open source, open hardware) although I still have much to learn about it.

Publications

To access all my publications on the institutional repository (ORBI), please go here.

Our citations according to Google Scholar are here.

Most of my publications are directly available, others (with publisher's constraints, symbolized by the padlock) are also available after filling a simple request form:

Software

CYTOMINE is a "Google Maps"-like rich internet application for remote visualization, collaborative and semantic annotation and automated analysis of high-resolution images. It is released under an open-source software license. It also includes a data mining module in Python with our latest algorithm developments for image classification, semantic segmentation, and landmark detection, and a Java module for content-based retrieval. It can be run on big servers for large-scale studies, or on laptops for small-scale works.

PiXiT, a Java software which implements our CVPR 2005 image classification method is available upon request for evaluation and non-commercial purposes, in collaboration with PEPITe. Newer extensions and improvments are not included in this version.

Conference Calendar

For years, for personal usage I'm trying to maintain a unofficial conference calendar (.ics file) in the fields of computer vision, bioimage informatics, machine learning, biomedical imaging.

In the field of computer vision, the conference listing from USC is far more complete.

Étudiants

Please contact me for Master final thesis proposals, traineeships, ... in bioimage informatics or machine learning for computer vision. Especially if you are interested to be involved in open-source software development using machine learning and modern web technologies and their applications to real-world (big) image data.

Misc

I listen very much to music (mostly ambient/electronica/modern classical/fields recordings) like in this selection.
I co-organized the Panoptica festival with friends and I'm now involved in the Supervue festival.
I also enjoy reading (society essays and "independent" comics), eating delicious vegetarian food, traveling, taking pictures, thinking, ...
