A la fin du Moyen Age l’historiographie normande connaît un nouvel essor par la rédaction dans la seconde moitié du XIVe siècle de la Grande Chronique de Normandie. Le texte relate l’histoire du duché de Normandie et du monde anglo-Normand entre 911 et 1204. En 911 le chef viking Rollon recevait du roi de France Charles le Simple le territoire de Neustrie contre promesse de défendre ses frontières et de se convertir au catholicisme. Les Normands feront croître leur territoire au-Delà des limites de la Manche, initiant ainsi une nouvelle dynastie royale en Angleterre. La Normandie sera rattachée en 1204 à la couronne française de Philippe Auguste. Tardivement mis en image au XVe siècle, le texte sera illustré de scènes typologiques, traditionnellement utilisées dans les chroniques médiévales. Puis, se développerons des images plus complexes et narratives. Le but étant toujours la mise en exergue de la dynastie anglo-Normande. Produits durant ou juste après la guerre de Cent Ans, les manuscrits s’inscrivent dans un contexte tout à fait singulier. L’histoire normande sera utilisée à des fins politiques pour servir les prétentions des belligérants ou pour éduquer le lectorat médiéval. Largement diffusée dans le nord de la France l’illustration des manuscrits a permis la mise en place d’une tradition iconographique relative à la dynastie anglo-Normande dans trois grands centres artistiques : la Normandie, Paris et les Flandres. Enfin, le texte sera remanié et continué afin de poursuivre l’histoire normande jusqu’aux temps présents de la production. La Grande Chronique de Normandie a survécu à l’apparition de l’imprimerie tout en perdant toutefois sa récente tradition iconographique / In the late Middle Ages, the writting of the GCN gave to the norman historiography a new growth in the second half of the 14th century. The text dealt with the history of the duchy of Normandy and the anglo-Norman world from 911 to 1204. In 911, the Viking chief Rollo received the territory of Neustrie from Charles the Simple, king of France, in exchange of the promise to defend the border and to become catholic. The Normans increased there territory over the Channel, thus they started a new dynasty in England. The Normandy has been attached to the french crown under the reign of Philippe Auguste. At a late stage, the text of the GCN has been illuminated with typologic scenes, traditionnaly used in medieval chronicals. Moreover, images became more and more complicated and narrative as well, whose purpose was still the highlighting ofthe anglo-Norman dynasty. The context of the making of the manuscripts is very specific in so far as they have been made during or shortly after the One Hundred Year War. The norman history will be used for the political interest of the belligerants as well as to educate the medieval readership. Widely spread in Nothern France, the illuminated manuscripts permitted the settlement of an iconographic tradition related to the anglo-Norman dynasty in three great artistic centres : the Nomandy, Paris and Flanders. Finally, the text has been changed and increased in order to go on the norman history till now. The GCN managed to go through the period of printing, therefore it lost its new iocnography recently gained.

This thesis explores Voxel Cone Tracing as a possible Global Illumination solutionon mobile devices.The rapid increase of performance on low-power graphics processors hasmade a big impact. More advanced computer graphics algorithms are now possi-ble on a new range of devices. One category of such algorithms is Global Illumi-nation, which calculates realistic lighting in rendered scenes. The combinationof advanced graphics and portability is of special interest to implement in newtechnologies like Virtual Reality.The result of this thesis shows that while possible to implement a state of theart Global Illumination algorithm, the performance of mobile Graphics Process-ing Units is still not enough to make it usable in real-time.

Nous introduisons un algorithme de décomposition intrinsèque multi-vue qui permet de ré-éclairer une scène extérieure en utilisant quelques images en entrée. Plusieurs applications comme l’architecture, jeux et films exigent de manipuler un modèle 3D d’une scène. Cependant, la modification de telles scènes est limitée par les conditions d’éclairage de capture. Notre méthode estime les images intrinsèques prises dans des conditions d’éclairage identiques avec des ombres. Nous utilisons conjointement une reconstruction 3D automatique et la direction du soleil pour obtenir la décomposition de chaque image en calques de réflectance et d’éclairage malgré l’inexactitude des données du modèle 3D. Notre approche est basée sur deux idées principales. Tout d’abord, nous raffinons l’estimation des paramètres de notre modèle de formation d’image en combinant la simulation d’éclairage 3D avec des méthodes d’optimisation basée image. Deuxièmement, nous utilisons ce modèle pour exprimer la réflectance en fonction de valeur de visibilité discrète pour l’ombre et la lumière, ce qui nous permet d’introduire un classificateur d’ombre robuste pour des paires de points dans une scène. Nos calques intrinsèques sont de qualité suffisante pour manipuler les images d’entrée. Nous déplaçons les ombres portées en créant une géométrie qui préserve les silhouettes d’ombre. Notre méthode est compatible avec les approches de rendu basé image et réduit les coûts de création de contenu 3D. Enfin, nous présentons une étude sur les limites du modèle de réflectance diffus et la difficulté d’appliquer les approches existantes dans le cadre de reconstruction 3D multi vue où les données sont imprécises. / We present a multi-view intrinsic decomposition algorithm that allows relighting of an outdoor scene using just a few photographs as input. Several applications such as architecture, games and movies require a 3D model of a scene. However, editing such scenes is limited by the lighting condition at the time of capture. Our method computes intrinsic images photos taken under the same lighting condition with existing cast shadows by the sun. We use an automatic 3D reconstruction from these photos and the sun direction as input and decompose each image into reflectance and shading layers, despite the inaccuracies and missing data of the 3D model. Our approach is based on two key ideas. First, we progressively improve the accuracy of the parameters of our image formation model by performing iterative estimation and combining 3D lighting simulation with 2D image optimization methods. Second we use the image formation model to express reflectance as a function of discrete visibility values for shadow and light, which allows us to introduce a robust shadow classifier for pairs of points in a scene. Our multi-view intrinsic decomposition is of sufficient quality for relighting of the input images. We create shadow-caster geometry which preserves shadow silhouettes and using the intrinsic layers, we can perform multi-view relighting with moving cast shadows. Our method allows image-based rendering with changing illumination conditions and reduces the cost of creating 3D content for applications. Finally, we present an initial study on the limitation of diffuse reflectance models for these computations.

The diploma thesis deals with light dosimeters and modern printing and coating techniques for thin-film formation. The subject of experimental study is the optimization of photosensitive compositions for the preparation of disposable, printed and thin-film dosimeters for visible light. Sensitivity, reproducibility and irreversibility of their color change were optimized. Compositions were calibrated for desired light dose. Functional samples for gallery were fabricated and stability of functional samples were tested at high temperatures of storing.

Background: Automobile lighting is a major function on any automobile to illuminate the road to let drivers and commuters see the road ahead. It also serves a variety of other purposes. However, it is now becoming a luxury design feature, with each automobile manufacturer having their own unique lamps. Every car manufacturer now has its own characteristic lights that can be recognized from a considerable distance, and they strive for homogeneity. As a result, it’s critical to check and assess a lamp's homogeneity during the product development phase to identify any potential flaws. Objectives: This research presents a HDRImage encoding for visualizing and verifying luminance data in image format. For an intuitive and subjective evaluation also the colour is used. Secondly, using the mean filter technique to validate an internal Volvo Cars lit surface homogeneity requirement and automate the time-consuming process. Lastly, using the ISOcontour approach to propose and implement a simple yet effective verification method for distributed light homogeneity. Methods: The research methods used in this study are literature review and experiment. To discover further about HDRImage encoding using luminance data, as well as existing light measurement and evaluation approaches, a literature review is conducted. The appropriate approaches for this study are then combined and implemented to produce a verification method that uses the homogeneity requirement to automatically verify lit surfaces. This thesis also presented ISOcontour lines as a way for evaluating distributed light. Results: The findings of this thesis demonstrate that it is possible to develop a method for verifying and evaluating luminance data obtained from simulation software and photometers without relying on any licensed software for light evaluation. The methods are, for visualisation using HDRImage encoding, a method to evaluate light such as false colour, ISOcontour lines for distributed light verification, and an automatic homogeneity verification approach for lit surface to make the verification of illumination process efficient. Conclusions:  Experiment provided a means of visualizing luminance data of both virtual and physical prototypes, verifying distributed light, and automatically verifying it surface homogeneity, while literature review assisted in gathering information in certain fields to better comprehend light evaluation methods.

A few experiments have been done focused on the right choice of an objective, lighting of the scene or setting of the cameras. A special equipment has been invented for a better process of measuring followed by experiment aimed at boring a cutter in materials chosen beforehand. The speed and the acceleration of the cutter was ana-lyzed by means of MotionMeasure software in another experiment.

This thesis deals with problem of computation of global illumination in real-time. Two methods are described. Namely Reflective Shadow Maps and Light Propagation Volumes. The first of them deals with the problem by using extended Shadow Mapping algorithm. The second one uses scene embedded into a 3D grid together with Spherical harmonics to compute light propagation in the scene. Furthermore this thesis contains results of measurement of the rendering speed of the Light Propagation Volumes algorithm with various settings on several machines. Quality of the resulting output of the algorithm is also evaluated.

Les capteurs d’images cherchent de nos jours non seulement à être performant mais également à être adaptés à leur environnement et à de nouvelles utilisations. On peut évoquer le cas des machines et véhicules autonomes par exemple. En raison de la qualité d’image et son coût, une vaste majorité des applications ont aujourd’hui adopté l’usage des pixels CMOS actifs à photodiodes pincées et à illumination par la face arrière.L’originalité de la solution proposée dans ce manuscrit repose l’intégration d’une photogate, utilisée par les capteurs CCD, au sein d’un pixel CMOS. Son utilisation optimise alors l’espace disponible dans le pixel et diminue le nombre d’implantation nécessaire à sa réalisation. Ce développement a également conduit à l’emploi d’une grille de transfert spécifique. Ces deux nouvelles structures auront toutes les deux été élaborées durant cette thèse notamment à l’aide de simulations et de structures de test.La caractérisation de ce nouveau pixel aura démontré de nombreux atouts : entre autres, l’augmentation de la charge à saturation et la réduction du courant d’obscurité. De plus, l’étude détaillée du courant d’obscurité indique une distribution davantage centrée. Celle-ci permet l’identification de contaminants et une meilleure tenue en température en comparaison à une photodiode classique.De nombreuses perspectives s’offrent à la structure telle que la réduction du pas du pixel ou son utilisation dans un environnement contraint en température. / Nowadays image sensors look neither to be efficient, but rather to be adapted to their environment or to new uses. Autonomous machines and vehicles can be mentioned for instance. Because of image quality and cost, a large majority of applications employs CMOS pixels and pinned back-side illuminated photodiodes.The originality of the solution proposed in this manuscript relies on the integration of a photogate, used by CCD sensors, inside a CMOS pixel. Its use optimize the available space inside the pixel and decrease the number of implantation needed to its realization. This development has also led to the use of specific transfer gate. Both structures have been created during this thesis and designed using simulation and specific test structures.The characterization of the developed pixel demonstrate many assets such as an increase of saturation charges and a reduction of dark current. Furthermore, a detailed study of the dark currant indicates a more gathered pixel distribution, allowing the identification of contaminants and a better temperature handling in comparison to a classical photodiode.The proposed structure offers many perspectives such as reduction of the pixel pitch or its potential use in an environment with a temperature constraint.
