Lestrade, Kévin. "Simulation de trajectoires complexes à l’aide d’un hexapode de mouvement : application aux sports de glisse." Thesis, Paris, ENSAM, 2016. http://www.theses.fr/2016ENAM0037/document.
The project SIMUSURF consists in using an hexapod to analyze the biomechanical response of a human subject positioned on the moving platform of the hexapod and submitted to a translation and/or rotation movement. This robot allows practice of sport activities where balanced specific conditions are required. Riding sports such as surf, ski or snowboard are sports for which special skills to steer the support (surfboard, snowboard or ski for instance) are needed. The development of a surf simulator, using the hexapod equipped with multi-axis force plates, will allow to study the relations between figure and biomechanical response of the surfer, the interindividual variability to execute a given movement and to optimise the actions of the person aiming at better performances.The development of this simulator from the hexapod has been approached from two aspects.- From an instrumentation and acquisition point of view, simulation of the trajectories corresponding to the movements of the set {surfer + board} on the ocean required the constitution of an experimental database to identify such a behavioral dynamic model of the interactions between the surfer, his board and the wave. For these in situ experimentations, instrumentation of a surfboard was required. The design of an instrumented board and the implementation of an acquisition protocol in the extreme conditions due to the marine environment have been one of the technological hurdles associated.- From a mechanical and robotics point of view, it was essential to optimize the control of the hexapode (a total of 6 actuators with the potential speed of 5 m/s) to reach the desired trajectory or multiaxial efforts to impose in the special case of a force complex command.To be realistic, a surfing simulator designed with an hexapod had to be able to reproduce the complex movements and high dynamic of a surfboard on a wave and submitted to the efforts of surfer. These specifications were reached by taking account of existing dynamic coupling phenomena between actuators and implementing effective multivariable control approach: CRONE approach synthesizing control laws both powerful and robust, that is resistant to imperfect knowledge of the controlled system
Marin, Antoine. "Le mouvement segmentaire au service du déplacement dans la marche : analyse couplée des deux niveaux." Thesis, Rennes 2, 2014. http://www.theses.fr/2014REN20039/document.
Walking is a complex mecanism involving trajectories generation in various environments and motion generation in order to follow the path. Then, it is dependent on environment, obstacles and peoples moving around but also on body capabilities. This complexity lead scientits to split walking analysis in two levels : trajectory generation in one hand, and motion generation in the othe hand. This work aim to provide a global walking analysis processus by linking trajectorires and motion generation. First, we explore walking trajectories throw a particular situation : pedestrians crossing. Here we take interest in trajectories and speed adaptations. Then, we sink for the link between trajectory and heelstrike. It lead us to develop a model for heelstrike generation based on trajectory. Finally, we take interest in walking motion simulation. By the use of local linearization, we provide a new methodology for joints joints angles generation

Zamzami, Ziad. "Analyse et exploitation de la dynamique naturelle des robots sous-actionnés." Thesis, Sorbonne université, 2018. http://www.theses.fr/2018SORUS408.
Humans and animals are capable of performing graceful and agile movements. One of the key ingredients for such complex behaviors is motor coordination to exploit their natural dynamics which results in a synergistic motion that surpasses their physical limits. Despite the existence of powerful tools such as nonlinear trajectory optimization, they are usually treated as a black box. This thesis introduces the Dynamical Coupling Map (DCM), a novel graphical analysis technique, to help gain insight into the resulting trajectory of the optimization and analyze the capability of underactuated robots while taking into consideration underactuation constraints and torque limits. The DCM analysis technique along with the three novel performance measures aptly named Natural Dynamics Indexes (NDI) demonstrate the pivotal role of exploiting the natural dynamics to exceed the robot's physical capability which is dictated by the input torques limits. Furthermore, the merits of the DCM analysis are demonstrated on several dynamic maneuvers such as the swing-up motion of a simplified model of a gymnast on high bar and standing high jump for a high-dimensional humanoid robot with arm swing. In addition, the DCM is extended from a posteriori analysis tool to a fundamental heuristic for generating dynamic motions by leveraging the probabilistic motion planning approach with a new natural dynamic based heuristic. Thus, introducing the Natural Dynamics based Tree (NDT), a novel sampling-based kinodynamic planning algorithm which plans a dynamic motion based on the natural dynamics of the system resulting in a more computational efficient motion planning and with high-quality motion solution
Fradet, Matthieu. "Contributions à la segmentation de séquences d'images au sens du mouvement dans un contexte semi-automatique." Phd thesis, Rennes 1, 2010. http://www.theses.fr/2010REN1S010.
Many computer vision applications require the extraction and tracking of the different video objects that compose a dynamic scene. In the context of post-production, the constraint of visual quality of the results is so high that a user must be able to add inputs easily and quickly in order to efficiently help the process. This thesis aims at proposing new motion-based segmentation algorithms. It is composed of two main parts. First, two sequential and semi-automatic methods are proposed for segmenting a video shot in regions of similar motion. Both exploit the multi-layered motion representation of a dynamic scene. It is based on different criteria (motion, colour, spatio-temporal coherence) that are combined into an objective function minimized with Graph Cuts. The second part introduces a new approach to automatically cluster sets of feature point trajectories. Each trajectory has its own life-span. Compared to motion estimated between two images only, motion information provided by a trajectory offer an extended temporal horizon that allows a better distinction of objects whose motions are different. The algorithms are validated on several different sequences with various dynamic contents

Maczyta, Léo. "Dynamic visual saliency in image sequences." Thesis, Rennes 1, 2020. http://www.theses.fr/2020REN1S046.
Our thesis research is concerned with the estimation of motion saliency in image sequences. First, we have defined an original method to detect frames in which a salient motion is present. For this, we propose a framework relying on a deep neural network, and on the compensation of the dominant camera motion. Second, we have designed a method for estimating motion saliency maps. This method requires no learning. The motion saliency cue is obtained by an optical flow inpainting step, followed by a comparison with the initial flow. Third, we consider the problem of trajectory saliency estimation to handle progressive saliency over time. We have built a weakly supervised framework based on a recurrent auto-encoder that represents trajectories with latent codes. Performance of the three methods was experimentally assessed on real video datasets
Chassat, Perrine. "Functional and Shape Data Analysis under the Frenet-Serret Framework : Application to Sign Language Motion Trajectories Analysis." Electronic Thesis or Diss., université Paris-Saclay, 2024. http://www.theses.fr/2024UPASM005.
This thesis, conducted in collaboration with MocapLab, a company specializing in motion capture, aims to determine the optimal mathematical framework and relevant descriptors for analyzing sign language motion trajectories. Drawing on principles of motor control, we identified the framework defined by the Frenet-Serret formulas, including curvature, torsion, and velocity parameters, as particularly suitable for this task. By introducing new curve analysis approaches based on the Frenet framework, this thesis contributes to developing novel methods in functional data analysis and shape analysis. The first part of this thesis addresses the challenge of smoothly estimating Frenet curvature parameters, treating the problem as parameter estimation of differential equation in SO(d), (d ≥ 1). We introduce a functional Expectation-Maximization algorithm that defines a unified variable estimation method in the SE(3) group, providing smoother estimators that are more reliable and robust than existing methods. In the second part, two new curve representations are introduced: unparametrized Frenet curvatures and the Square Root Curvatures (SRC) transform, establishing new Riemannian geometric frameworks for smooth curves in ℝᵈ, (d ≥ 1). Leveraging higher-order geometric information and parametrization dependence, the Square Root Curvatures transform outperforms the state-of-the-art Square-Root Velocity Function (SRVF) representation on synthetic results. Given a collection of curves, this type of geometry allows us to define efficient statistical criteria for estimating Karcher mean shapes on the associated Riemannian shape spaces, proving particularly effective on noisy data. Finally, this developed framework opens the door to more practical applications in sign language processing, including the study of power laws on our data and the development of a generative model for a point motion in sign language

Lachal, Aimé. "Etude des trajectoires de la primitive du mouvement brownien." Lyon 1, 1992. http://www.theses.fr/1992LYO10060.
In this work we gather several results we obtained on the behavior of the integral of linear Brownian motion, and more particularly on the various distributions related to the first passage times of the trajectories by fixed thresholds. For instance, we were able to explicitly determine the joint law of the couple made up of the first passage time of the integrated process by a fixed point and of the related location of Brownian motion. We retrieved in particular the marginal laws of this couple discovered by M. Goldman (1971) and Ju. P. Gor'kov (1975), as well as the law of the first return time to the origin obtained by H. P. McKean (1963). This result enabled us to resolve several open problems. In particular, we obtained the distributions of several functionals associated with the integral of Brownian motion: successive passage times, last passage time, sojourn time, excursions. . . We next studied the location of the primitive of Brownian motion when this latter reaches a single or double barrier. Such functionals naturally arise in some optimization problems studied by M. Lefèbvre (1989). A new approach enabled us to find and improve its results. We finally derived the distribution of certain functionals related to the integral of Brownian motion, this latter being subjected to a parabolic or cubic drift. We retrieved in particular a result of P. Groeneboom (1989) concerning Brownian motion with a parabolic drift. An exhibition of some still open problems completes this work
Pop, Ionel. "Détection des événements rares dans des vidéos." Thesis, Lyon 2, 2010. http://www.theses.fr/2010LYO22023.
The growing number of video data makes often difficult, even impossible, any attemptof watching them entirely. In the context of automatic analysis of videos, a recurring request is to identify moments in the video when something unusual happens.We propose several algorithms to identify unusual events, making the hypothesis that these events have a low probability. We address several types of events, from those generates by moving areas to the trajectories of objects tracked. In the first part of the study, we build a simple tracking system. We propose several measures of similarity between trajectories. These measures give an estimate of the similarity of trajectories by taking into account both spatial and/or temporal aspects. It is possible to differentiate between objects moving on the same path, but with different speeds. Based on these measures, we build models of trajectories representing the common behavior of objects, so that we can identify those that are abnormal.We noticed that the tracking yields bad results, especially in crowd situations. Therefore, we use the optical flow vectors to build a movement model based on a codebook. This model stores the preferred movement directions for each pixel. It is possible to identify abnormal movement at pixel-level, without having to use a tracker. By using temporal coherence, we can further improve the detection rate, affected by errors of estimation of optic flow. In a second step, we change the method of construction of this model. With the new approach, we can extract higher-level features — the equivalent trajectories, but still without the notion of object tracking. In this situation, we can reuse partial trajectory analysis to detect rare events.All aspects presented in this study have been implemented. In addition, we have design some applications, like predicting the trajectories of visible objects or storing and retrieving tracked objects in a database

The increase in life expectancy of baby boom generations in developed countries would often be accompanied by functional limitations, disability, increasingly observed in the geriatric population. The general objective of this thesis was to contribute to the knowledge of the evolution of the functional independence of older people in a heterogeneous population. First, it was to identify homogeneous groups in a heterogeneous population of elderly people following the same functional independence trajectory over a two-year period, and potential predictive factors. Second, it was to analyze the clinical consequences of trajectories and patient survival over the same observation period. The SMAF (Système de Mesure de l'Autonomie Fonctionnelle) and ADL (Activities of Daily Living) scales were used as indicators for measuring independence. Analysis were performed from a sample of 221 patients of UPSAV (Unit for Prevention, Monitoring and Analysis of Aging) cohort. We used three methods including trajectory analysis including GBTM (Group-Based Trajectory Modeling), k-means and ascending hierarchical classification. The results suggest three distinct trajectories of functional independence: stable, stable then decline, continuously decline. The predictors of trajectories obtained using logistic regression are socio-demographic, medical and biological criteria. Patients assigned to the loss of independence trajectory (continuously altered trajectory) reported high proportions of injurious falls. Based on a Cox model, neurocognitive disorders, heart failure, involuntary weight loss and alcohol were revealed as predictors of death. We conclude from this work that the two-year longitudinal analysis identified homogeneous subgroups of elderly people in terms of changes in functional independence. The prevention of UPSAV becomes a useful even if the utility level is not the same. Prevention and screening of the loss of independence of the elderly person followed at home must be anticipated in order to delay the deterioration and to maintaining the autonomy. Future analyses should focus on exploring large cohorts of older people to confirm and generalize our research

In this thesis, we explore two problems related to managing and mining moving object trajectories. First, we study the problem of sampling trajectory data streams. Storing the entirety of the trajectories provided by modern location-aware devices can entail severe storage and processing overheads. Therefore, adapted sampling techniques are necessary in order to discard unneeded positions and reduce the size of the trajectories while still preserving their key spatiotemporal features. In streaming environments, this process needs to be conducted "on-the-fly" since the data are transient and arrive continuously. To this end, we introduce a new sampling algorithm called spatiotemporal stream sampling (STSS). This algorithm is computationally-efficient and guarantees an upper bound for the approximation error introduced during the sampling process. Experimental results show that stss achieves good performances and can compete with more sophisticated and costly approaches. The second problem we study is clustering trajectory data in road network environments. We present three approaches to clustering such data: the first approach discovers clusters of trajectories that traveled along the same parts of the road network; the second approach is segment-oriented and aims to group together road segments based on trajectories that they have in common; the third approach combines both aspects and simultaneously clusters trajectories and road segments. We show how these approaches can be used to reveal useful knowledge about flow dynamics and characterize traffic in road networks. We also provide experimental results where we evaluate the performances of our propositions

This work discusses two fundamental problems relating to grasping hand : determining a kinematic model of the hand and to realise a data base of prehensile postures of the hand. A new kinematics model of the hand is developed with the main specificity: the deformation in arch of the palm realised by a two additional degrees of freedom for the ring and pinkie fingers. Ideal joints and rigid segments characterise the kinematic skeleton of the hand. The kinematical model is described using a robotic formalism developped by Denavit-Hartenberg. Ten hand postures are unregistered during an experimentation in vivo and using different shapes (sphere, cylinder and cube) and dimensions of object (40 mm, 60 mm, 80 mm). Qualitative and quantitative validation are realised using this model in the environment of an existent in digital human model (MAN3D)

My Ph. D manuscript deals with the problem of markerless human motion capture. We propose an approach that relies on the use of multiple cameras and that avoids most of the constraints on the environment and the use of markers to perform the motion capture, as it is generally the case for industrial systems. The absence of markers makes harder the problem of extracting relevant information from images but also to correlate this information between. Moreover, interpreting this extracted information in terms of joint parameters motion is not an easy task. We propose an approach that relies on occluding contours of the human body. We studied the link between motion parameters and the apparent motion of the edges in images. Minimizing the error between the extracted edges and the projection of the 3D model onto the images allows to estimate the motion parameters of the actor. Among the opened issues, we show that using video based motion capture allows to provide additional hints such as contacts between body parts or between the actor and its environment. This information is particularly relevant for improving character animation

This scientific object of this thesis is the French "independant" punk space : we are interesed in the social genesis of this style, in the dispositions to become, and to be, "punk", in the political and artistic ageing and its contemporary specifities of existence. By studying the social morphology of the avant-garde Anglo-Saxon and French punks, through the lens of international exanges of cultural and symbolic goods, it testifies, by using the "prosopography" analysis, how the ways of doing and the ways of being thought as "Do it yourself" are handed down and re-adjusted by the generations come. From beyond this point, this thesis explores successively the trajectories, the topography of the contemporary punk space, the body-learning and the incorporation of this taste that defines the punk corporal "hexes", in order to reveal, finally, in what way these careers are created, pratically, by the specific modalities of politico-artistic ageing

In this thesis, we are interested in quantifying the dynamics of intracellular particles, as proteins or molecules, inside living cells. In fact, inference on the modes of mobility of molecules is central in cell biology since it reflects the interactions between the structures of the cell. We model the particle trajectories with stochastic processes as the interior of a living cell is a fluctuating environment. Diffusions are stochastic processes with continuous paths and can model a large range of intracellular movements. Biophysicists distinguish three main types of diffusions, namely Brownian motion, superdiffusion and subdiffusion. These different diffusion processes correspond to distinct biological scenarios. A particle evolving freely inside the cytosol or along the plasma membrane is modelled by Brownian motion; the particle does not travel along any particular direction and can take a very long time to go to a precise area in the cell. Active intracellular transport can overcome this difficulty so that motion is faster and direct specific. In this case, particles are carried by molecular motors along microtubular filament networks and their motion is modelled with superdiffusions. Subdiffusion can be observed in two cases i/ when the particle is confined in a microdomain, ii/ when the particle is hindered by molecular crowding and encounters dynamic or fixed obstacles. We develop a statistical test for classifying the observed trajectories into the three groups of diffusion of interest namely Brownian motion, super-diffusion and subdiffusion. We also design an algorithm to detect the changes of dynamics along a single trajectory. We define the change points as the times at which the particle switches from one diffusion type (Brownian motion, superdiffusion or subdiffusion) to another. Finally, we combine a clustering algorithm with our test procedure to identify micro domains that is zones where the particles are confined. Molecular interactions of great importance for the functioning of the cell take place in such areas

AIn estimation and motion analysis domain we present two studies. Ln the first, we are interested in the study of periodic events. We propose a connectionist approach to extract the dominant behavior of the observed phenomena of a periodic sequence of images. It is based on Kohonen maps and built a "short cycle". In a second part, we propose a connectionist method for estimating local motion by exploiting the WTA algorithm based on minimizing an energy function. It also helps to regulate the displacement field by taking into account the discontinuities. It uses a concept we have called "neural interaction". The method may also take into consideration the coincidence between motion and the photometrie border. The independent of neurons processing allows us parallel processing and hence an estimate of movements in real time

In this PhD thesis we present a method to assure ambient assistance in urban environment, using a mobile agent, in order to anticipate assistance if needed. Therefore, we have to understand the human behavior and The pedestrian’s needs. We determine how to focus on a moving subject and how to use interaction between A mobile agent and A pedestrian for confirmation of the need to provide assistance. Therefore, the trajectory type concept is used to define the first step of analyses, which is called the approach step. Combining this step with the field information provided by the mobile agent, a certain type of assistance will be insured. In terms of observation, two different views are employed to detect assistance requirements, i. E. , the Fix Intelligent Device and the Ambient Intelligent Devices, both communicating by wireless. The Fix Intelligent Device is composed by a fix camera standing on a very top view allowing the detection of possible motions and an algorithm to classify the trajectories, using neural network. This classification result is subsequently communicated to the mobile agent. In our thesis, a Touch Ambient Intelligent Device is represented by mobile robot with three degrees of freedom, including a 3D camera (KinectTM) to detect human body poses, and additionally a touch screen tablet to interact with the subject. The conclusion can be made that human intervention may be required only IN critical cases

The thesis is composed of two parts. In the first part, I followed the history of the movement of non-aligned countries since its appearance in the international scene I have analyzed the five criterias on non-alignment and its eight summit conferences as from Belgrade in 1961 up to Harare in 1986. The political principals and objectives of the movement are summarized in the creation of a new world system based on the democracy and sovereign equality of states. Every summit conference has added important contributions to peace and human well fair. In the second part, I analyzed the policy of the movement regarding the international question. In fact, the activities of the movement cannot be isolated from the political, economic and social world events. The interest of the movement for maintaining international peace and security are concentrated into two fields: the disarmament and the reform of United Nations system. The movement has not achieved all its objectives because of so many reasons related to its incapacity in the political, economic and strategic fields. The internal conflicts, the divergences among member states and the interference of the big power in the internal affairs of the non-aligned countries represented another challenge before the movement. In conclusion, two hypotheses summarize well in which direction is steering the movement in the future: the movement cannot resist to the pressure on it and it disappears from the international scene

This dissertation concerns the visual perception of human motions, more precisely, the importance of motor processes in perceptual processes. Perception-action relationships were analysed in children from ages 7 to 11. This dissertation aimed at showing that the perception of human movement depends, at least to a certain extent, on the individual's own motor experience. The first part of experiments concerns the visual perception of pointing, tansport and grasping movements,in adult's production. The children's task was to predict the size of the target pointed or which the grasped object was displaced and the weight of object grasped or displaced. The second part of experiments concerns motor sequence, with two successive movements : grasping a glass to throw it or to displace il, pointing successively two target, the second target was small or large, writing a cursive two digrams. The movement presented on a computer screen, presented the first component of a sequential gesture. The task of children was to predict the forthcoming gesture by using the kinematic information provided by the first movement component. At the end of the experiment, subjects were asked to produce movements perceived. Results show that perceptual performance of children depends on the observer's motor competence. This research supports the idea of a strong link between perceptual and motor processing : level of motor control development has an effect on the perception of human motions

Since the 1970s, a process of deindustrialisation has taken place in all industrialized countries. This process comes partly from the exacerbation of international competition but also from structural changes. The industry continues to designate all activities that contribute to the production of material goods. Its jobs and functions evolve, however, leading to deep territorial divergences.In this context, the traditionally industrial territories are said to be weakened. Faced with their probable decline, multiple avenues of redevelopment are highlighted, based on cultural, heritage, tourism or residential levers. Paradoxically, their future productive capacities are rarely questioned. This thesis raises the question of a productive future for these territories, in France, especially when they are located outside large urban areas.Assuming that the origins of territorial change can be both exogenous and endogenous, and that territories are largely dependent on their past, this thesis proposes an analysis that takes into account local trajectories over the last fifty years. This research is based on a mixed methodology combining quantitative elements, at the scale of all French industrial living areas, and qualitative from three case studies: Bocage Bressuirais, Romans-sur-Isère and Annonay. This thesis invites us to take into account the diversity of territories and to reconsider their overall economic and sociodemographic fragility. In doing so, it shows that a productive renewal is possible. The thesis finally details the multiple paths that can be borrowed face to the emergence of new challenges like digital, sustainability and social innovation

This thesis deals with the use of trajectories extracted from videos. The approach is invariant to translation, to rotation and to scaling and takes into account both shape and dynamics-related information on the trajectories. A hidden Markov model (HMM) is proposed to handle lack of observations and parameters are properly estimated. A similarity measure between HMM is used to tackle three dynamic video content understanding tasks: recognition, clustering and detection of unexpected events. Hierarchical semi-Markov chains are developed to process interacting trajectories. The interactions between trajectories are taken into used to recognize activity phases. Our method has been evaluated on sets of trajectories extracted from squash and handball video. Applications of such interaction-based models have also been extended to 3D gesture and action recognition and clustering. The results show that taking into account the interactions may be of great interest for such applications
