Повний текст джерелаThis thesis presents several approaches aiming to analyze fluorescence microscopy images in the field of cell biology. It is essentially focused on techniques for localization and tracking of multimolecular complexes in multidimensional data (2D, 2D+t, 3D and 3D+t). The first part of this work is dedicated to the extraction and characterization of fluorescent biological structures using wavelet based segmentation. Various biological studies performed in collaboration with various research groups are detailed, such as a study about morphometric analysis of organelles of cell constrained by micro patterns or the localization of the mid1p protein in yeasts. In a second part, a tracking algorithm of labeled molecular structures is presented. It is based on the linking over time of segmented objects by minimizing the association costs by a simulated annealing technique. This method is particularly well adapted in a lot of biological situations, because it allows modeling of many events like birth, death, fusion and fission. A single molecule (mono-disperse DNA 166kbp) dynamics analysis has been made using this tracking technique in order to extract the variations of the molecular diffusion coefficient. The third part describes a set of analyzes with the goal to study the spatial and temporal localization of transport intermediates involved in the membrane trafficking tagged by chimerical GFP-Rab6A and GFP-Rab6A’ proteins. Several complementary approaches are used to extract quantitative information and to describe the underneath biological processes

Повний текст джерелаThis thesis focuses on longitudinal time to event data possibly large along the following tree axes : number of individuals, observation frequency and number of covariates. We introduce a penalised estimator based on Cox complete likelihood with data driven weights. We introduce proximal optimization algorithms to efficiently fit models coefficients. We have implemented thoses methods in C++ and in the R package coxtv to allow everyone to analyse data sets bigger than RAM; using data streaming and online learning algorithms such that proximal stochastic gradient descent with adaptive learning rates. We illustrate performances on simulations and benchmark with existing models. Finally, we investigate the issue of video game design. We show that using our model on large datasets available in video game industry allows us to bring to light ways of improving the design of studied games. First we have a look at low level covariates, such as equipment choices through time and show that this model allows us to quantify the effect of each game elements, giving to designers ways to improve the game design. Finally, we show that the model can be used to extract more general design recommendations such as dificulty influence on player motivations

Повний текст джерелаThe university growth in the number of disabled students (2005-103 law), and is facing the complex challenge of inclusion (2013-595 law). The law on equal opportunities and rights made it compulsory admission, and the law school and refounding the Republic requires the establishment of inclusive university. We question the issue of inclusion of students with disabilities in both the socialization aspect of the anthropological approach in the aspect of the production-transmission of academic knowledge and their accessibilisation by the didactic approach. The inventory of the issue is in a critical historical analysis of texts and institutions, in order to realize the conceptual evolution of the concepts according to their origin. We analyze and critique of official documents and institutional positioning. Building on scientific research we return to our account some conceptual elements (liminality, stigmata, rites of interaction, rites of institution) to continue the anthropological approach to disability. Didactics of joint action that we present seems quickly respond to relational needs inclusion in the academic higher education. Our thesis adopts a clinical and collaborative approach, giving pride of place to actors, students with disabilities or not, and teachers. We listen to three students with disabilities, three regular students (all Bachelor, two of Sociology and Anthropology) and two teachers (one experienced, the other rookie). These clinical interviews collected at Rogerian method of active listening give rise to a set of corpus analyzed in the thesis and delivered in full in appendices to serve as empirical contributions to scientific research. We urge cross approach, anthropological and didactic, description and video analysis filmed TD sociology and cross analysis of experienced teachers. What about the relationship and the production-transmission of knowledge in tutorials, with and for students with disabilities at the University today? If the clinical lighting does not allow us to report comprehensively on developments of the current reality, at least it allows us better to ask some questions in the light of societal and anthropological issues of inclusion of cognitive socialization university
Garcia, garcia Miguel. "Analyse de l'hypovigilance au volant par fusion d'informations environnementales et d'indices vidéo." Thesis, Université Grenoble Alpes (ComUE), 2018. http://www.theses.fr/2018GREAT120.
Повний текст джерелаDriver hypovigilance (whether caused by distraction or drowsiness) is one of the major threats to road safety. This thesis is part of the Toucango project, hold by the start-up Innov+, which aims to build a real-time hypovigilance detector based on the fusion of near infra-red video evidence and environmental information. The objective of this thesis is therefore to propose techniques for extracting relevant indices as well as multimodal fusion algorithms that can be embedded in the system for real-time operation. In order to work near ground truth conditions, a naturalistic driving database has been created with the collaboration of several transport companies. We first present a scientific state of the art and a study of the solutions available on the market for hypovigilance detection. Then, we propose several methods based on image (for the detection of relevant indices on the head, eyes, mouth and face) and data processing (for environmental indices based on geolocation). We carry out a study on the environmental factors related to hypovigilance and develop a contextual risk estimation system. Finally, we propose multimodal fusion techniques of these indices with the objective of detecting several hypovigilance behaviors: visual or cognitive distraction, engagement in a secondary task, sleep deprivation, microsleep and drowsiness

Повний текст джерелаDue to the growth of video traffic over the Internet in recent years, HTTP AdaptiveStreaming (HAS) solution becomes the most popular streaming technology because ithas been succesfully adopted by the different actors in Internet video ecosystem. Itallows the service providers to use traditional stateless web servers and mobile edgecaches for streaming videos. Further, it allows users to access media content frombehind Firewalls and NATs.In this thesis we focus on the design of a novel video streaming delivery solutioncalled Backward-Shifted Coding (BSC), a complementary solution to Dynamic AdaptiveStreaming over HTTP (DASH), the standard version of HAS. We first describe theBackward-Shifted Coding scheme architecture based on the multi-layer Scalable VideoCoding (SVC). We also discuss the implementation of BSC protocol in DASH environment.Then, we perform the analytical evaluation of the Backward-Sihifted Codingusing results from queueing theory. The analytical results show that BSC considerablydecreases the video playback interruption which is the worst event that users can experienceduring the video session. Therefore, we design bitrate adaptation algorithms inorder to enhance the Quality of Experience (QoE) of the users in DASH/BSC system.The results of the proposed adaptation algorithms show that the flexibility of BSC allowsus to improve both the video quality and the variations of the quality during thestreaming session.Finally, we propose new caching policies to be used with video contents encodedusing SVC. Indeed, in DASH/BSC system, cache servers are deployed to make contentsclosed to the users in order to reduce network latency and improve user-perceived experience.We use Linear Programming to obtain optimal static cache composition tocompare with the results of our proposed algorithms. We show that these algorithmsincrease the system overall hit ratio and offload the backhaul links by decreasing thefetched content from the origin web servers
Leny, Marc. "Analyse et enrichissement de flux compressés : application à la vidéo surveillance." Thesis, Evry, Institut national des télécommunications, 2010. http://www.theses.fr/2010TELE0031/document.
Повний текст джерелаThe increasing deployment of civil and military videosurveillance networks brings both scientific and technological challenges regarding analysis and content recognition over compressed streams. In this context, the contributions of this thesis focus on: - an autonomous method to segment in the compressed domain mobile objects (pedestrians, vehicles, animals …), - the coverage of the various compression standards commonly used in surveillance (MPEG-2, MPEG-4 Part 2, MPEG-4 Part 10 / H.264 AVC), - an optimised multi-stream processing chain from the objects segmentation up to their tracking and description. The developed demonstrator made it possible to bench the performances of the methodological approaches chosen for a tool dedicated to help investigations. It identifies vehicles from a witness description in databases of tens of hours of video. Moreover, while dealing with corpus covering the different kind of content expected from surveillance (subway stations, crossroads, areas in countryside or border surveillance …), the system provided the following results: - simultaneous real time analysis of up to 14 MPEG-2 streams, 8 MPEG-4 Part 2 streams or 3 AVC streams on a single core (2.66 GHz; 720x576 video, 25 fps), - 100% vehicles detected over the length of traffic surveillance footages, with a image per image detection near 95%, - a segmentation spreading over 80 to 150% of the object area (under or over-segmentation linked with the compressed domain). These researches led to 9 patents linked with new services and applications that were made possible thanks to the suggested approaches. Among these lie tools for Unequal Error Protection, Visual Cryptography, Watermarking or Steganography

Повний текст джерелаThe development of sensors has always followed the ambition of industrial and scientific people to observe the unobservable. High speed cameras are part of this adventure, revealing invisible dynamics such as cracks formation or subtle mosquito flight. Industrial high speed vision is a very competitive domain in which cameras stand out through their acquisition speed. This thesis aims to broaden their capacity by augmenting the initial acquisition with dynamic models. This work proposes to develop methods linking in real time a model with a real system. Aimed benefits are interpolation, prediction and identification. Three parts are developed. The first one is based on video processing and submits to use kinematic elementary and generic models. An algorithm of motion estimation for large movements is proposed but the generic nature does not allow a sufficient knowledge to be conclusive. The second part proposes using sequential data assimilation methods known as Kalman filters. A scheme to assimilate video data with a mechanical model is successfully implemented. An application of data assimilation in modal analysis is developed. Two multi sensors real time assimilation schemes for nonlinear modal identification are proposed. These schemes are integrated in two applications on 3D reconstruction and motion magnification
