AI-based method for microplastic particle identification and classification based on image analysis and with Raman spectra as reference


Catégorie : Post-doctorant


Post-doctoral position open for September 2024

 
AI-based method for microplastic particle identification and classification based on image analysis and with Raman spectra as reference
 
Dans le cadre d’un projet au sein de l’ESIEE, membre fondateur de l’Université Gustave Eiffel, les laboratoires ESYCOM et LIGM collaborent avec la jeune start-up IZONICS. Leur objectif est de faire progresser la maturation d'une technologie innovante pour la détection et la reconnaissance de microparticules plastiques dans l'eau, à la fois économique et efficace [1].
 
Cette technologie repose sur une combinaison de la spectroscopie Raman et de l'imagerie microscopique [2, 3]. Alors que la spectroscopie Raman est aujourd'hui bien maîtrisée, son association efficace avec l'imagerie microscopique reste encore largement inexploitée. Pourtant, cette combinaison pourrait offrir plusieurs avantages, tels qu'un traitement plus rapide et le développement de nouvelles méthodes pour l'analyse des images microscopiques [4].
 
L'objectif de ce projet est de développer et mettre en œuvre des méthodes complètes et efficaces pour la détection et la reconnaissance des particules, ouvrant ainsi de nouvelles opportunités et applications pour l'analyse de l'eau. Plusieurs étapes seront nécessaires, telles que la validation des paramètres de la chaîne d'acquisition de données, l'évaluation et le développement de méthodes d'analyse des données, ainsi que la définition et la mise en œuvre d'applications de démonstration. Une part importante du projet sera également consacrée à la création d'un jeu de données, actuellement inexistant pour la partie imagerie microscopique.
 
Si le candidat le souhaite, il pourra en option contribuer à la mise en œuvre de la partie matérielle du système.
 
Status: R&D employee of the startup company IZONICS,
Duration: 12 months, with perspective enrolment as permanent staff (CDI).
Scientific and technical supervision:
- Prof. Eva Dokladalova, Université Gustave Eiffel, ESIEE Paris, LIGM Lab.
- Prof. Tarik Bourouina, Université Gustave Eiffel, ESIEE Paris, ESYCOM Lab. and Co-founder of IZONICS

2 Missions
In this project, within ESIEE School of Engineering, a founding member of Université Gustave Eiffel, the ESYCOM and LIGM laboratories join forces with the young start-up IZONICS, whose aim is to advance the maturation of an innovative technology for low-cost and effective detection and recognition of microplastic particles in water [1].
This technology is based on a combination of Raman spectroscopy and microscopic imaging [2, 3]. While Raman spectroscopy is fairly well mastered today, its effective combination with microscopic imaging has yet to be fully exploited. However, this combination could bring several advantages, from faster processing to the possibility of developing new methods for the analysis of microscopic images [4].
The objective of this project is to work and implement complete and efficient methods for the detection and recognition of particles, to offer new opportunities and applications for water analysis.
Several steps will have to be carried-out, such as validation of the parameters of the data acquisition chain, evaluation and development of data analysis methods, and definition and implementation of demonstration applications. A significant part will also be devoted to the creation of the dataset (non-existent today for the microscopic imaging part).
If the candidate is interested, he can optionally contribute to the implementation part of the hardware system.
 
3 Activities
- join a research lab to conduct innovative R&D and join a startup team to contribute to its developement
- conduct research in the field of data analysis in the field of AI-based methods applied to microplastic particle detection and recognition
- participation in the implementation and prototype validation
- coordination of development outsourcing
- supervision of internship students can be considered.
