Le projet ARCADIA vise à développer une méthode automatique d’analyse des décors sur des tessons de céramique réalisés à la molette pour faciliter l’interprétation de ce patrimoine archéologique. Cette automatisation doit remplacer la procédure manuelle effectuée par l’archéologue, devenue trop fastidieuse avec l’augmentation du corpus (38000 tessons). L’objectif in fine est de réussir à associer automatiquement les décors à la molette du potier qui les a créés. Dans ce contexte, nous avons développé une chaine complète depuis la numérisation des tessons jusqu’à la classification automatique des décors selon leur style de motifs(carré, losange, chevrons, oves, etc). Les travaux présentés proposent plusieurs contributions mettant en oeuvre des méthodes d’analyse d’images et d’apprentissage automatique. A partir du nuage de points 3D, une carte des profondeurs est obtenue. Une méthode originale de détection automatique de la région saillante focalisée sur le décor est proposée. Ensuite les décors sont caractérisés pour effectuer leur classification. Un nouveau descripteur, appelé Blob-SIFT, est proposé pour collecter les signatures seulement dans les zones pertinentes du décor. Cette approche adaptée à chaque décor, permet à la fois de réduire considérablement la masse de données et d’améliorer les performances de classification. Nous proposons également une approche apprentissage profond, puis, une approche hybride combinant les vecteurs de caractéristiques locales extraites par Blob-SIFT et la caractérisation globale du décor fournie par l’apprentissage profond qui améliore encore les performances de classification. / The ARCADIA project aims to develop an automatic method for analyzing engraved decorations on ceramic sherds to facilitate the interpretation of this archaeological heritage. It is to replace the manual and tedious procedure carried out by the archaeologist since the corpus increased to more 38000 sherds. The ultimate goal is to grouping all the decorations created with the same wheel by a poter. We developped a complete chain from the 3Dscanning of the sherd to the automatic classification of the decorations according to their style (diamonds, square, chevrons, oves, etc). In this context, several contributions are proposed implementing methods of image analysis and machine learning. From the 3Dpoint cloud, a depth map is extracted and an original method is applied to automatically detect the salient region centered onto the decoration. Then, a new descriptor, called Blob-SIFT, is proposed to collect signatures only in the relevant areas and characterize the decoration to perform the classification. This approach adapted to each sherd, allows both to reduce significantly the mass of data and improve classification rates. We also use deep learning, and propose an hybrid approach combining local features extracted by Blob-SIFT with global features provided by deep learning to increase the classification performance.

Il progetto di ricerca ha indagato la diffusione e le caratteristiche dei vetri in uso a Milano in età romana a partire dallo studio di un certo numero di reperti provenienti da scavi archeologici e tramite l’approfondimento di alcune tematiche relative ad aspetti produttivi e tecnologici. La ricerca ha preso spunto dallo studio dei materiali provenienti dagli scavi nei cortili dell’Università Cattolica (1986-2004), ed è stata estesa poi ad altri contesti di scavo per ampliare la base dei dati su cui ricostruire il quadro del vetro in uso nella città e delle problematiche ad esso inerenti. Il quantitativo di reperti individuati e la loro rappresentatività statistica permettono di tracciare un quadro dei materiali in uso nella vita quotidiana, le relazioni tipologiche tra alcuni gruppi di oggetti, vagliare le ipotesi sull’esistenza di una produzione locale e sui rapporti commerciali con altre aree, relativamente al periodo che va dall’inizio della diffusione dei recipienti in vetro (seconda metà del I sec. a.C.) fino al V sec. d.C. La ricerca si è avvalsa di analisi archeometriche ed ha enucleato anche alcuni temi di indagine specifica, in particolare sulle tecniche di lavorazione e di decorazione dei vetri a mosaico e dei manufatti con decori incisi. / Finds from recent archaeological excavation and analysis of older records are piecing together an increasingly detailed picture of the social context of Roman Milan: the material culture helps patch together a collage of the urban centre whose central position on the river plain North of the Po helped it become theatre to important events and intense industrial activity, attracting peoples of differing cultures and resources. This thesis studies Roman glass finds from Milan using the archaeological record and archaeometric analyses with the aim of reconstructing the framework of glass use in everyday life from the introduction of glass vessels in the mid-first century B.C. up to the fifth century A.D., considering relationship between individual groups of products, the hypothesis of a local glass industry and trade routes. The research, originating from post-excavation work on the courtyards of the Catholic University was extended to several unpublished Milanese excavations: the glass finds from these contexts, from both burial grounds and settlement sites, constitute a significant and statistically valid sample. Some in-depth technological examinations contribute to an understanding of certain questions still under debate: in particular on mosaic glass and engraved samples

DISERTAČNÍ PRÁCE Univerzita Karlova v Praze Filozofická fakulta Ústav pro dějiny umění Studijní program Dějiny výtvarného umění Jan Mergl Výtvarný vývoj produkce Harrachovské sklárny v Novém Světě 1850-1940 Art Development of the Production of the Harrach Glassworks in Nový Svět 1850-1940 Abstract Vedoucí práce: Doc. PhDr. Jana Kybalová, CSc. 2014 ABSTRACT Highly regarded throughout the world, Bohemian glass is also acknowledged as a cultural phenomenon in its own right and the Harrach glassworks in Nový Svět in Krkonoše indisputably ranks among the most accomplished companies that have had a determining influence on the world renown of Czech glassmaking. First documented in the early 18th century, the glassworks has been in existence for three hundred years. However, its prominent status among Bohemian producers of glass is not only due to its long history. What makes it noteworthy is its traditionally outstanding craftsmanship and technological facilities, and mainly its foresighted efforts to employ and further enhance diverse techniques in working with crystal and coloured glass. Thus, the factory was able to readily respond to the changes in the styles of glass as these developed from the 18th to the 20th centuries. This work is the outcome of long-term, focused research of archival sources, especially...

The design of cultural centre is situated in part Kozia Hôrka( well-known city swimming pool), in its advantage takes natural scenery and calm atmosphere of place. Into action of performance brings a message in form of body of reservoir, function of centre is divided into small parts placed in area Kozia Hôrka. Orientation of objects comes mainly from local natural ispirations. Complex is multifunctional in concept, counts with several sorts of culture - sports events. Whereby the main function of swimming pool is preserved and added for higher comfort of inhabitants. Architecture of objects comes from idea of floating leaf on water level and body of reservoir. Objects stylizely illustrate this idea. The design takes the game of solids of organic and strictly ortogonal shapes. Two mutual opposites, in interaction. Objects smoothy and with respect encroach the environment, which is enough marked by human. Simplicity in used materials ( glass, steel, wood ) give transparency and purity to whole solution.
