Céline MANCAS-THILLOU holds a PhD in Applied Sciences (FPMs, 2006) and two Master degrees, in Audiovisual Systems and Networks Engineering (ESIGETEL, 2002) and in Applied Sciences (FPMs, 2004). She is working with the TCTS Lab since January 2003 and is collaborating with the research center Multitel. Her research deals with text detection, extraction, segmentation and degraded character recognition, first in SYPOLE project and now in several projects, among RECITE. She has been a visiting PhD student at the University of Bristol for 3 months in 2005 to work on Super Resolution Text for an embedded application. She is also a member of the network of excellence Similar and OpenInterface Foundation. Nowadays Céline works in the Administration division of research and technology transfer of the University of Mons.
She has been a visiting PhD student at the University of Bristol for 3 months in 2005 to work on Super Resolution Text for an embedded application.
News:
  • The website of the project RECITE has been created. RECITE is my post-doc project to deal with engraved characters and automatically-built recognizers
  • Done, my PhD thesis is written, defended, printed and downloadable!
  • The pole of excellence *Technologies de l information* is ON and I organized (as regularly as possible) some seminars between researchers.

Abilities:
She is now working on camera-based text extraction and character recognition and her abilities are:
  • Low-level image processing
  • Binarization, Wavelet denoising
  • Neural Networks
  • Color Clustering
  • Super Resolution
  • Log-Gabor filters
Thanks to several projects in image and video processing in Esigetel and Dassault Systèmes (6 months), she has also performed:
