Aims and scope – WOMS 2018

Thank’s to all for this great WOMS18, see you on the next in 2020 …


This Workshop still aims at addressing new trends and recent advances in the characterization of dissolved organic matter (DOM) in marine and inland waters, using spectroscopic techniques associated with advanced signal and image processing tools. It will be the fourth international workshop dedicated to DOM spectroscopy. The preceding edition of WOMS took place in Granada (Spain) in 2010, Toulon (France) in 2013 and Sopot (Poland) in 2015. This year it is from 23th to 27th october at Carqueiranne.

Nice place to be 😉

WOMS 2018 invites original contributions about the characterization of DOM in marine and inland waters using fluorescence spectroscopy, coupled with advanced signal and image processing tools, among which improved data analysis, detection, clustering, separation, reconstruction, tracking and real-time monitoring. Prospections for future innovation in applied fluorescence spectroscopy to environmental material are welcome.

The purpose of WOMS 2018 is to provide a forum for discussing new and effective approaches in the area of fluorescence spectroscopy for the analysis of environmental data. WOMS 2018 also offers to signal/image and environment communities the opportunity to meet, in order to strengthen their dialogue and interactions on topics of common interest.

Topics of interest

They include, but are not limited to:

Fluorescence measurements : Signal and image processing for fluorescence data:
– Physico-chemical parameters influencing the DOM spectroscopic measurements – Pre- and post-processing (noise reduction, image filtering, smoothing, inner effect correction)
– Inner filtering effect correction methods and their domains of application – Reconstruction of the Fluorescence Emission-Excitation Matrices (EEM) of the separated
– Measurement standardization and calibration, instrumental corrections, use of standards fluorophores from few observations or with possible missing data
– Laser-induced, time-resolved fluorescence spectroscopy and lifetime of fluorophores – Best way to deal with a non-negative and/or sparse constraint
– In situ fluorescence, sensors, on-line measurements for environmental monitoring – Best way to initialize the factorization algorithms
– New real-time data processing – Best way to estimate the number of fluorophores in PARAFAC analysis
– Could it be possible to build an international numeric library? – Detection/decision, estimation and clustering of fluorophores

Recent trends in non-negative tensors factorizations raise significant theoretical challenges to provide sound mathematical grounds to such methods (non-negative rank, possible sparse constraints, regularization, realtime processing, high dimensional problems and computational cost).
