Texto completo da fonteArtificial intelligence is a relatively recent research domain. With it, many breakthroughs were made on a number of problems that were considered very hard. Fine-grained classification is one of those problems. However, a relatively small amount of research has been done on this task even though itcould represent progress on a scientific, commercial and industrial level. In this work, we talk about applying fine-grained classification on concrete problems such as tree bark classification and mould classification in culture. We start by presenting fundamental deep learning concepts at the root of our solution. Then, we present multiple experiments made in order to try to solve the tree bark classification problem and we detail the novel dataset BarkNet 1.0 that we made for this project. With it, we were able to develop a method that obtains an accuracy of 93.88% on singlecrop in a single image, and an accuracy of 97.81% using a majority voting approach on all the images of a tree. We conclude by demonstrating the feasibility of applying our method on new problems by showing two concrete applications on which we tried our approach, industrial tree classification and mould classification.

Texto completo da fonteModeling the spatial configuration of objects in an image is a subject that is still little discussed to date, including in the most modern computer vision approaches such as convolutional neural networks ,(CNN). However, it is an essential aspect of scene perception, and integrating it into the models should benefit many tasks in the field, by helping to bridge the “semantic gap” between the digital image and the interpretation of its content. Thus, this thesis aims to improve spatial configuration modeling ,techniques, in order to exploit it in description and recognition systems. ,First, we looked at the case of the spatial configuration between two objects, by proposing an improvement of an existing descriptor. This new descriptor called “force banner” is an extension of the histogram of the same name to a whole range of forces, which makes it possible to better describe complex configurations. We were able to show its interest in the description of scenes, by learning toautomatically classify relations in natural language from pairs of segmented objects. We then tackled the problem of the transition to scenes containing several objects and proposed an approach per object by confronting each object with all the others, rather than having one descriptor per pair. Secondly, the industrial context of this thesis led us to deal with an application to the problem of re-identification of scenes or objects, a task which is similar to fine recognition from few examples. To do so, we rely on a traditional approach by describing scene components with different descriptors dedicated to specific characteristics, such as color or shape, to which we add the spatial configuration. The comparison of two scenes is then achieved by matching their components thanks to these characteristics, using the Hungarian algorithm for instance. Different combinations of characteristics can be considered for the matching and for the final score, depending on the present and desired invariances. For each one of these two topics, we had to cope with the problems of data and segmentation. We then generated and annotated a synthetic dataset, and exploited two existing datasets by segmenting them, in two different frameworks. The first approach concerns object-background segmentation and more precisely the case where a detection is available, which may help the segmentation. It consists in using an existing global segmentation model and exploiting the detection to select the right segment, by using several geometric and semantic criteria. The second approach concerns the decomposition of a scene or an object into parts and addresses the unsupervised case. It is based on the color of the pixels, by using a clustering method in an adapted color space, such as the HSV cone that we used. All these works have shown the possibility of using the spatial configuration for the description of real scenes containing several objects, as well as in a complex processing chain such as the one we used for re-identification. In particular, the force histogram could be used for this, which makes it possible to take advantage of its good performance, by using a segmentation method adapted to the use case when processing natural images

Texto completo da fonteDen mekaniserade bataljonens främsta sensor att samla in underlag till underrättelsesektionen är spaningsplutonen. Spaningsplutonen på mekbataljon har bytt organisation över åren och gått från att vara ett terrängbils eller bandvagnsburet förband till sin nuvarande form med stridsfordon 90. Men har förbandet använts på rätt sätt sedan det tillfördes stridsfordon? Hur bör framtidens chefer nyttja plutonen för att maximera effekten?
Arbetet baseras på de reglementen som finns idag samt intervjuer med personal tillhörande spaningsplutonerna och bataljonsstaber. Utöver det kommer en jämförelse med US Army Armored Cavalry göras.
The mechanized battalion foremost instrument of gathering information to its intellegence cell is the reconnaissance platoon. The reconnaissance platoon on the mechanized battalion has evolved over the years from being a unit using crosscountry vehicles to its modern shape with Combat vehicle 90. But have the unit been used the right way since then? And how should tomorrows commanders use the recon platoon for maximum output?
This work will be based on the manuals that are valid today and interviews with staff officers and officers that belong to the recon platoons. The results will be compared with US Army Armored Cavalry.
Borello, Alex. "Reconnaissance de langages en temps réel par des automates cellulaires avec contraintes". Thesis, Aix-Marseille 1, 2011. http://www.theses.fr/2011AIX10127.
Texto completo da fonteThis document deals with cellular automata as a model of computation used to recognise languages. In such a domain, it is always difficult to provide negative results, that is, typically, to prove that a given language is not recognised in some function of time by some class of automata. The document focuses in particular on the low-complexity classes such as real time, about which a lot of questions remain open since several decades.In a first part, several techniques to weaken further still these classes of languages are investigated, thereby bringing examples of negative results. A second part is dedicated to the comparison of cellular automata with another model language recognition, namely multi-head finite automata. This leads to speed-up theorem when finite automata are oblivious, which makes them a priori weaker than in the general case but leaves them a nontrivial power

Texto completo da fonteThe thesis deals with the "sériephile" mobilization, i.e. the movement for the recognition of series in the French media, from the 80s to the early 2010s. It aims at understanding the logics of action of the main protagonists through semi-structured interviews, while also paying careful attention to a variety of publishing mediums they used. Through a detailed analysis of the careers of those who promoted series and of what they say, we identified three "generations" that structured this mobilization.A first generation came out at the end of the 80s, they promoted series at a moment when TV was broadly stigmatized in France. Throughout the 90s, different mediums are tried out, leading to a gradual specialization between amateurs and professionals, in collaboration with new, younger series lovers. This second generation stood up for series in new ways and advocated the need for a defense of popular culture at large. In the 2000s, a third generation appears, that faces a proliferation of analyses on series through the Internet and the death of the specialized press. While previous generations "lived for" series before they "live on" it, it is now the other way around. At the same time, cultural hierarchies reappear, not between TV series and cinema anymore but within series themselves

Texto completo da fonteThe question of the links between sports policies and developments suppose to analyse the whole logics of production of the main sports places, which are socio-politics, spatials, culturals or purely sportings. According to a geohistoric study of these logics, in a local/global articulation, the evolution towards a recognition of the place of sport in society and city development made into three successive periods according to the weight of great players. This recognition goes through a growing number of players who take into account the sports development from a local point of view, in a context of industrial and post-industrial town. Until the sixties private and public initiatives are in strong opposition. From the sixties to the eighties, to the boost of state then town councils, a true publics sports policy developped in accordance with the french model (pyramid-shaped organization from mass sports to elite sports) who favours a logic of public service. At last, until the nineteens, use forms of sports developments appear : the town council stays the womb of local public policies for sports, but other players, privates (profesionnal clubs, commercial organizations, free practisings), or publics (town councils), assert according to economic and politic strategies who put sport in the heart of image and city development issues

Texto completo da fonteOur everyday life is highly dependent on mobile embedded systems. In order to make them suitable to differentapplications, they have underwent size reduction and lifetime extension. However, these improvementsare currently limited by the possibilities of the integrated circuits technologies. In order to push back theboundaries, it is necessary to reconsider the whole digital signal processing chain from scratch to sustain thepower consumption reduction in this kind of system. This work develops on the first hand a strategy thatsmartly uses the level-crossing sampling scheme and on the other combines this sampling method with eventlogicto highly reduce the power consumption in mobile embedded systems. A discretisation method adaptedto the recognition of physiological patterns application is described. A first event-logic (asynchronous) prototypeimplemented on FPGA proved the potential benefits that an adapted sampling scheme could offersto reduce activity compared to a uniform sampling scheme. Electrical simulations performed on a secondprototype, also designed in asynchronous logic, with CMOS AMS 0.35 μm technology, validated a high gainin power consumption

Texto completo da fonteThis study focuses on biological numeric picture processes. It aims to define and implement new automated measurements at large scale analysis. Moreover, this thesis addresses: The incidence of the proposed methodology on the results reliability measurements accuracy definition and analysis proposed approaches reproducibility limits when applied to plant biology.This work is part of cells organization study, and aims to automatically identify and analyze the cell lines in microscopic mosaic wood slice pictures. Indeed, the study of biological tendencies among the cells lines is necessary to understand the cell migration and organization. Such a study can only be realized from a huge zone of observation of wood plane. To this end, this work proposes:- a new protocol of preparation (slices of sanded wood) and of digitizing of samples, in order to acquire the entire zone of observation without bias,- a novel processing chain that permit the automated cell lines extraction in numeric mosaic pictures,- reliability indexes for each measurement for further efficient statistical analysis.The methods developed during this thesis enable to acquire and treat rapidly an important volume of information. Those data define the basis of numerous investigations, such as tree architectural analysis cell lines following and/or detection of biological perturbations. And it finally helps the analysis of the variability intra- or inter- trees, in order to better understand the tree endogenous growth

Texto completo da fonteAdmissibility of evidence is one of the most crucial and complicatedissues in the European Union’s area of freedom, security and justice. However, thedifficulties regarding the use of evidence gathered in one Member State inproceedings in another Member State through the mechanisms of judicialcooperation seems to have been underestimated by the European Union legislator,and this despite the success of criminal proceedings with a cross-border characterbeing considered a priority for the last fifteen years. Indeed, the EU’s criminal policyhas been striving for the strengthening of the efficiency of judicial cooperationbetween judicial authorities. This requires the improvement of the instrumentsdedicated to obtaining criminal evidence. Thanks to the principle of mutualrecognition of judicial decisions in criminal matters, based on mutual trust betweenMember States, the differences between and potential incompatibilities of nationalsystems should not be an obstacle to the free circulation of evidence in the EUcriminal justice area.However, this theoretical justification is not sufficient to ensure mutual admissibility ofevidence, as the good administration of evidence remains a national issue, with awide margin of appreciation accorded to the national judge. Furthermore, both thestudy of national procedural norms and the study of the European Union legalframework show deficiencies, requiring a coherent concept for the protection offundamental rights in criminal proceedings at the EU-level. A better and harmonisedprotection of procedural guarantees is the path to ensure the mutual admissibility ofevidence, overcoming national differences

Texto completo da fonteThe present thesis aims to understand how audience and critical reception of politically and socially engaged art exhibitions articulates itself in the museum context in Quebec. In order to do so, two case studies will be examined: Art et féminisme (1982) and Pour la suite du Monde (1992). Within the scope of this thesis, a thorough study will be facilitated by selecting exhibitions which took place in a single institution, the Musée d’art contemporain de Montréal. Before directly addressing reception and in order to better define the artistic and theoretical context of the 1980’s and 1990’s, the first chapter will be dedicated to the different theories and practices regarding exhibitions as they were developed in that period. As such, the work of exhibition practitioners and theorists Jérôme Glicenstein, Mieke Bal, Yves Michaud, Nathalie Heinich and Michel Pollak, as well as Daniel Buren, will be summarised. The second and third chapters will exclusively address the Art et féminisme and Pour la suite du Monde exhibitions. While their reception will be examined, the specific conceptual and socio-historical context in which they were deployed will be detailed. The aim of this exercise is to fully comprehend the way in which an exhibition enunciates its subject matter when the latter is closely linked to its political, cultural and institutional reality.

Texto completo da fonteThis research explores homeless individuals' perception of their penalization and incarceration experience. Penalization of homeless individuals is an increasingly frequent phenomenon, due to a rise in the number of statements of offense served following infractions to municipal by-laws, to Société des Transports de Montréal by-laws or to the Code de Sécurité Routière. Penalization differs from criminalization : whereas criminalization results from the application of the Criminal Code, penalization follows for minor infractions or incivilities. Ultimately, penalization leads to incarceration : as they default on fines, individuals are increasingly sentenced to jail terms. The objective of this research is to better grasp how homeless individuals perceive penalization. It focuses on its effects on their material life, on their relationship with the system's actors and on their perception of the judicial system through their interaction with it. Ingrained in the conceptual framework of recognition (Honneth, 2000), the experience of penalization and incarceration sheds light on the relationship between homeless individuals and the justice system. This research makes use of complementary methodologies. The first one, draws on 29 interviews conducted with homeless individuals regarding their penalization and street life experience. The second one consisted of a descriptive statistical analysis of the 29 individuals' legal records, which included criminal and penal infractions and the procedural steps associated with each infraction.
