Current Research Topics

My current focus very much lies in the domain of Document Image interpretation, and how raw data, extracted from document image processing techniques can be elevated to the rank of information through the combination of formal[13] and statistical learning techniques on the one hand, and the modeling of the context semantics on the other hand. 

General Interests and Previous Subjects

Reproducible Research and Performance Analysis

Part of this work is very tightly related with the DARE paradigm and the associated DAE platform and its follow-up project DIA-Tribe.

Digital Humanities

Various on and off going interactions with the ANRT Typography research lab in Nancy, in trying to figure out how image analysis can help capturing typographic information in Renaissance documents (Re-Typograph). Partially in collaboration with Boise State University.

Graphical Document Image Analysis

From 2000 to 2009, I've been involved in graphical document analysis mainly focusing on extracting robust features[12] for indexing[11] and recognition[10] of graphical document collections[9].

Visual Servoing

During 1998-2000 I took a brief excursion into the domain of visual servoing and tracking. Besides a significant part of technology transfer, main scientific contributions related to metric and non metric visual stereoscopic robot control by addressing uncalibrated stereo control through integration of epipolar constraints[5,6] into previous results[7]. Other contributions consisted in work on fully un-calibrated stereo control methods[8].

Image Recognition and Indexing

This is work that was mainly done during my PhD. (1994-1998). It concerns object recognition in real-world images from structural data, indexed using affine and projective quasi-invariants indexing keys. Initially only considering image contours[1], it was extended to geometrically coherent combinations of contours and interest patches[2,3]. It may actually give a key to integrating geometric coherence to bag-of-word methods. It was successfully tested in an industrial environment for the identification of mechanical parts of car engines.

One of the more fundamental parts of this work has been the study of the inherent computational complexity related to content-based image indexing[4]. This has been one of the first published works noticing that indexing multimedia data imperatively needs to take into account computational complexity related to high dimensional metric spaces
