Qui suis-je ? / Who am I?
Je suis directrice d'un département d'ingénierie solution chez THALES Communications & Security, au sein duquel nous réalisons les ingénieries systèmes bout en bout des solutions de communications pour les forces armées : Armée de l'Air, Marine nationale et Armée de Terre. J'y contribue à fournir des solutions modernes et résiliente de communications aux forces, à y insérer les innovations technologiques en ligne avec l'état de l'art, et à développer de manière continue les équipes techniques pour que leur travail soit à la fois passionnant et utile.
Précédemment, j'ai occupé différents rôles de directrice technique, architecte système et responsable de projets toujours autour des solutions de communications radio-mobiles, en particulier dans le domaine aéro-naval militaire, mais aussi pour des usages civils. Mes sujets d'intérêt techniques concernent les enjeux d'architecture et d'optimisation des moyens de transmissions, et vous pourrez trouver plus de détails sur les sujets non-classifiés sur lesquels j'ai travaillé dans l'oblet "Mes travaux".
I am the director of a solution engineering department at THALES Communications & Security, where we carry out end-to-end system engineering communications solutions for the armed forces: Air Force, Navy and Army. In this position, I contribute to provide modern and resilient communications solutions to the forces, to insert technological innovations in line with the state of the art, and to continuously develop the technical teams so that their work is both exciting and useful.
Previously, I have held various roles as technical director, system architect and project manager always around mobile radio communication solutions, in particular in the military air and naval domain, but also for civilian uses. My technical interests are related to the architecture and optimisation of communications systems, and you can find more details on the unclassified topics I have worked on in the "Mes travaux" section.

Introduction to M-JPEG 2000 video coding standard
1. Introduction to Motion JPEG 2000
Basically, Motion JPEG 2000 consists of successive independent still images compressed using JPEG 2000 standard [1] (intra frames) described before. As a consequence and like Motion-JPEG, Motion JPEG 2000 does not exploit temporal redundancies. However, the wavelet coding technique significantly outperforms techniques using block-based Discrete Cosine Transform (DCT). Furthermore, because frames are coded independently, the damaging impact of transmission errors does not propagate across consecutive frames. In addition, intra-frame coding requires a low computational complexity and a low buffer memory size. Moreover, due to the precise post-compression rate control, minimal coding delay is introduced. Finally, Motion JPEG 2000 also provides with important features such as resolution and quality scalability.
This leads to many advantages:
- the codestream is easier to process- there is almost no latency (only Intra frames)
- there is no error propagation from one frame to the other
- it is possible to use JPEG 2000 error resilience tools
- a syntax for the RTP/UDP payload is defined by IETF
- it will hopefully soon become a commonly recognised format as are Motion JPEG and JPEG
but also one major drawback:
- files have larger sizes due to the absence of temporal compression.
The characteristics presented for JPEG 2000 are valid for MJPEG 2000 and won't consequently be repeated here, but the main element that should be taken into consideration in any wireless transmission framework is the capacity to resist to error transmission that is offered by MPEG2000 when compared to other standards such as MPEG-4 or H.264. As a matter of fact, as shown in Table 1, the PSNR results (confirmed by perceptual tests also performed by the EPFL) are much better than those observed for MPEG-4 in various configurations (eventhough MPEG-4 FGS case was not considered here).

MJPEG 2000 appears as a potential
candidate for at least performance derivation, eventhough it should also be
compared with MPEG-4 FGS.
