Manchun Lei

Manchun Lei is a researcher at the Laboratory of Geographic Information Sciences and Technologies (LaSTIG) under the National Institute of Geographic and Forest Information (IGN) in France. She holds a PhD in Instrument and Image Informatics from the University of Burgundy (2011) and has been actively involved in remote sensing and image physics research since 2008.

• Education: Doctorat en Instrument et Informatique de l'Image (2011), Master en Vision (2008) from Université de Bourgogne, France.

Research Interests focus on radiometric correction of images in urban and coastal environments, hemispherical imagery for radiometric measurements, ocean color image simulation, and optical remote sensing for coastal monitoring. Her work addresses geometric constraints in geostationary ocean color missions and leverages hydrodynamic-biogeochemical models for coastal image simulation.

Publication Trends highlight expertise in geostationary sensor simulation, radiometric normalization, and coastal/ocean color remote sensing. Key methodologies include CycleGAN for image harmonization, log-transformed band ratio algorithms, and hemispherical radiance field calibration.

Teaching includes radiometric correction at the ENSG-Geomatique Master PPMD program since 2017. She supervised the 2019 internship of Islame Dhibou (MSc Optics, Vision, Image, Multimedia) on hemispherical radiance systems.
