Image Processing & Colorimetry Researcher

About Me

I am an image processing and color science researcher working at the intersection of applied optics, remote sensing, and material appearance, with a specific focus on multispectral and hyperspectral imaging, spectrophotometry, BRDF-based material modeling, spatial filtering, and video compression algorithms.

Through my Master's in Advanced Imaging and Material Appearance: Metrology and Modeling (AIMA) at Université Jean Monnet (Faculté des Sciences et Techniques) and the Laboratoire Hubert Curien, part of the Manutech-SLEIGHT Graduate School for light-surface engineering in Saint-Étienne, France, I built a strong foundation in image formation theory, radiometry, colorimetry, and the optical and visual characterization of materials and surfaces. This training shaped my ability to apply optics and computer science together across advanced imaging for aerospace, healthcare and security; material appearance and quality control for automotive, luxury goods and manufacturing; and printed image analysis for graphic arts and secure document printing.

Building on this foundation and a broader background in image sciences, I combine theoretical optics, colorimetry, and programmatic data processing using Python and MATLAB, from laboratory spectral measurement through to complete processing pipelines.

Core Expertise

Multispectral & Hyperspectral Imaging

Acquisition and processing of spectral image cubes; band-by-band reflectance analysis, pigment and material identification (e.g. Spectral Angle Mapper), and spectral data pipelines for remote sensing and heritage/material science applications.

Remote Sensing & Surface Characterization

Radiometric interpretation of surface and material reflectance under varying illumination and viewing geometry, applied to both terrestrial imaging and controlled laboratory measurement setups.

Material Appearance & BRDF Modeling

Measurement and modeling of gloss, translucency, and light–surface interaction (BRDF / subsurface scattering), applied to human skin rendering, automotive finishes, and luxury-goods material quality assessment.

Colorimetry & Spectrophotometry

Color-difference metrics (CIELAB, CIEDE2000) and their coherence with human visual perception, chromaticity measurement under multiple illuminants, and spectrophotometric instrumentation.

Computational Image Processing

Spatial- and frequency-domain filtering, halftoning, optical-flow-based motion detection, and document/image restoration algorithms.

Video & Image Compression

Motion estimation for interframe coding, Fourier/DCT-based transforms for intraframe reduction, and hybrid codec design balancing fidelity against bitrate.

Tools & Methods

Python (NumPy, SciPy, scikit-image, OpenCV) MATLAB Spectral Angle Mapper Goniospectrophotometry BRDF / BSSRDF Modeling Fourier & DCT Transforms Optical Flow Analysis Hyperspectral Data Cubes
