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. This internship will investigate perceptually aware color-processing techniques that reflect key characteristics of human vision, including the effects of luminance on color perception and chromatic contrast.

As part of the team, the intern will assess the state of the art in perceptually aware color gamut mapping, 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 perceptually aware color gamut mapping.

Identify promising directions for integrating human-vision 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, display technologies such as OLED or local-dimming LCD, or perceptual image quality is a plus.

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

Key Topics

Deep learning

Image and color processing

Human visual system and perceptual metrics

Expected Outcomes

A concise review of current perceptual 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). Ce stage portera sur des techniques de traitement de la couleur fondées sur la perception, qui reflètent des caractéristiques essentielles de la vision humaine, notamment les effets de la luminance sur la perception des couleurs et le contraste chromatique.

Au sein de l'équipe, la personne recrutée dressera l'état de l'art du gamut mapping (adaptation des couleurs d'un gamut à un autre) fondé sur la perception, identifiera les approches prometteuses, concevra et implémentera des prototypes, puis évaluera les méthodes obtenues. Les techniques d'apprentissage profond et de réseaux de neurones seront privilégiées l
