About the Internship

The Video Production Services team develops technologies that enhance video production and delivery for modern displays, with a particular focus on high dynamic range (HDR) and wide color gamut. These technologies rely on conversions both in luminance and color and that may affect the perception of very sensitive colors, such as the skin tones. This internship will investigate the management of skin tones during those conversions, investigating color-processing techniques that reflect key characteristics of human vision, including the effects of luminance on color perception and chromatic contrast, especially on skin tones.

As part of the team, the intern will assess the state of the art in skin tone aware color gamut mapping techniques, identify promising approaches, design and implement prototypes, and evaluate the resulting methods. Deep learning and neural networks techniques will be preferred where they offer a meaningful advantage.

Key Responsibilities

Review and synthesize current research on skin tone aware color gamut mapping techniques.

Identify promising directions for integrating skin tone related metrics into color-processing pipelines.

Design and implement optimization methods, including neural-network-based approaches

Evaluate experimental results and iteratively refine the proposed methods.

Qualifications

Currently pursuing a master’s degree in computer science, electrical engineering, applied mathematics, or a related field. Master 2 level, 6 months internship.

Skills in Python and C/C++.

Experience with a deep-learning framework such as PyTorch or TensorFlow, including the training and evaluation of convolutional neural networks.

Knowledge of image processing, or perceptual image quality is a plus.

Fluent English

An autonomous, curious, and rigorous approach to research and experimentation.

Key Topics

Image and color processing

Human visual system and perceptual metrics related to skin tone

Deep learning

Expected Outcomes

A concise review of current skin tone color gamut-mapping techniques.

New proposals for local gamut-mapping methods.

Working prototypes of the proposed methods.

Technical reports documenting the algorithms, experiments, results, and conclusions.

Location

Rennes, France

Le stage

L'équipe Video Production Services développe des technologies qui améliorent la production et la diffusion vidéo pour les écrans modernes, avec un accent particulier sur la grande plage dynamique (High Dynamic Range, HDR) et le large gamut de couleurs (Wide Color Gamut). Ces technologies reposent sur des conversions de luminance et de couleur, susceptibles d'affecter la perception de couleurs très sensibles, comme les carnations (tons de peau). Ce stage portera sur la gestion des carnations au cours de ces conversions, en étudiant des techniques de traitement de la couleur qui reflètent des caractéristiques essentielles de la vision humaine, notamment les effets de la lumi
