Moubtahij, Redouane El. "Transformations polynomiales, applications à l'estimation de mouvements et la classification." Thesis, Poitiers, 2016. http://www.theses.fr/2016POIT2268/document.
The research relies on modeling the dynamic functional information from the fields of apparent movement using basic orthogonal polynomials. The goal is to model the movement and texture extracted for automatic analysis and recognition of images and videos. We are interested both in human movements as dynamic textures. Orthogonal polynomials bases were studied. This approach is particularly interesting because it offers a multi-resolution and a multi-scale decomposition. The first contribution of this thesis is the definition of method of image spatial decomposition: the image is projected and partially rebuilt with an appropriate choice of the degree of anisotropy associated with the decomposition equation based on polynomial transformations. This spatial approach is extended into three dimensions to retrieve the dynamic texture in videos. Our second contribution is to use image sequences that represent the geometric parts as initial images to extract color optical flow. Two descriptors of action, spatial and space-time, based on the combination of information of motion / texture are extracted. It is thus possible to define a system to recognize a complex action (composed of a series of fields of motion and polynomial texture) in a video
Crenn, Arthur. "Reconnaissance d’expressions corporelles dans des mouvements de personnes en vue de la synthèse de style." Thesis, Lyon, 2019. http://www.theses.fr/2019LYSE1341.
The theme of my thesis concerns the recognition and synthesis of facial and body expressions. Our problem is to study, understand and extract the elements that translate a person's emotional state from the expressions of his face and body, in order to recognize and also to synthesize the emotion or style in a gesture. This dual objective of recognition and synthesis will make it possible to generalize new modes of interaction in applications such as video games, human-machine interaction, etc. Indeed, these applications can be enriched with scenarios that could be adapted to the emotional state of the user. To answer this problem, the crucial point is to understand "where" the expression information is located in an action. Indeed, in a few seconds, a human knows how to characterize an expression he sees while recognition algorithms are still far from it, especially for body expressions where, to our knowledge, little work has been done compared to the recognition of facial expressions. Concerning the recognition of expressions, our objective is, first of all, to propose features capable of recognizing the expression carried by a movement. To do this, the main problem is to separate the movement achieved from the perceived expression. Concerning the recognition of facial expressions, we are interested in the societal problem of parental protection. To do this, it is necessary to understand and know how to recognize facial expressions of children. To solve this problem, we have built and proposed a new database to help the computer vision community understand the specificities of facial expressions of children's faces. Secondly, we also hope that the various descriptors proposed in recognition of body expressions can be used in the field of animation synthesis. Indeed, in the field of animation, the creation of an action that conveys an emotion or a style requires a lot of work, know-how and time for an animator to propose stylized animations. For example, in a video game, to create such animations, it is often necessary to have a huge database of movements including each style for each virtual character. To have such a database, one of the following two methods is often used. The first consists in capturing all the movements made by different actors playing different styles. In the second, it is the graphic designer who must create the various animations by hand using animation software. Our objective in this context is to use the descriptors quantifying the expression detected in recognition of facial and body expressions in order to develop tools capable of changing / editing the style or expression of an animation. These tools will assist and facilitate the work of graphic designers by allowing them to quickly synthesize a stylized "primal animation". These stylized animations can be refined in post-processing by adding an artistic touch to the generated animation

This thesis discusses the Piquetero movement in Argentina and its successive transformations during the 2000s into an extensive network of service provider organizations throughout the territory from a sociohistorical and ethnographic perspective. This movement was born out of the collective actions of the unemployed and precarious workers in the late 1990s against the effects of "neoliberal" reforms, and takes its name from one of their preferred modes of protest, the roadblock or picket. Since its beginnings, the Piquetero movement has been the subject of a double treatment by the State, between repression and recovery in the context of the establishment of Conditional Cash Transfer Programs. In this new configuration of targeted public action, it is now up to the State to delegate the distribution of social assistance to a network of organizations, given their territorial proximity to the underprivileged populations. However, this thesis shows that this fuzzy wicket role, which tends to introduce in one way or another the competition amid the organizations, has thus quickly contributed to fragment the piquetero space, and produces ambivalent effects on the practices and the trajectories of the participants. The thesis is based on mixed methods, qualitative and quantitative, from a large 40-month field survey conducted between 2000 and 2015 in two Argentinian provinces. On the one hand, through an ethnography and in-depth biographical interviews with leaders, delegates and grassroots activists (N=104), we observed the interactions between these different categories. A prosopography of the leaders (N=76) allowed us, on the other hand, from the statistical methods of factor analysis (ACM) and hierarchical classification (CAH), to report on the structuring of this space of organizations. In the first part, the thesis focuses – with the support of archives and interviews – on the conditions of the gradual crystallization of a social movement into a space of organizations. We sought here to understand the context, the stakes and the means of action of this protest movement, relating its inscription to the evolution since the beginning of the XXth century of the relations between State, political parties and unions. The second part of our thesis is devoted to the analysis of activist practices and forms of supervision within organizations. The opening of the black box of the organizations thus reveals to what extent their internal functioning results from the capacity of a set of intermediaries to carry out a work of representation, mobilization and management of resources among working classes particularly willing to engage in the long term. The statistical examination of the trajectories of leaders also informed us about the resources that were necessary to occupy such a position and also about the effects of their engagement to their individual trajectories. Finally, a third part serves to apprehend associative practices within organizations. Restoring the recruiting logics and the profiles of the recruits has shown in the long term both the conditions of the commitment of these unemployed and precarious workers and the effects on their trajectories. The observation of practices, especially during assemblies, shows the principles of supervision stretched between activism and entrepreneurship which weighed on the participants. If this fraction of precarious people testifies within the working classes of forms of mobilization and resistance particularly exemplary, they also tend to deploy modes of accommodation to organizations, differentiated according to their socialization, and the volume and nature of their resources
Arango, Duque Carlos. "Analysis of Micro-Expressions based on the Riesz Pyramid : Application to Spotting and Recognition." Thesis, Lyon, 2018. http://www.theses.fr/2018LYSES062/document.
Micro-expressions are brief and subtle facial expressions that go on and off the face in a fraction of a second. This kind of facial expressions usually occurs in high stake situations and is considered to reflect a humans real intent. They have been studied to better understand non-verbal communications and in medical applications where is almost impossible to engage in a conversation or try to read the facial emotions or body language of a patient. There has been some interest works in micro-expression analysis, however, a great majority of these methods are based on classically established computer vision methods such as local binary patterns, histogram of gradients and optical flow. Considering the fact that this area of research is relatively new, much contributions remains to be made. ln this thesis, we present a novel methodology for subtle motion and micro-expression analysis. We propose to use the Riesz pyramid, a multi-scale steerable Hilbert transformer which has been used for 2-D phase representation and video amplification, as the basis for our methodology. For the general subtle motion analysis step, we transform an image sequence with the Riesz pyramid, extract and lifter the image phase variations as proxies for motion. Furthermore, we isolate regions of intcrcst where subtle motion might take place and mask noisy areas by thresholding the local amplitude. The total sequence is transformed into a ID signal which is used fo temporal analysis and subtle motion spotting. We create our own database of subtle motion sequences to test our method. For the micro-expression spotting step, we adapt the previous method to process some facial regions of interest. We also develop a heuristic method to detect facial micro-events that separates real micro-expressions from eye blinkings and subtle eye movements. For the micro-expression classification step, we exploit the dominant orientation constancy fom the Riesz transform to average the micro-expression sequence into an image pair. Based on that, we introduce the Mean Oriented Riesz Feature descriptor. The accuracy of our methods are tested in Iwo spontaneous micro-expressions databases. Furthermore, wc analyse the parameter variations and their effect in our results

Behavior is often conceived as resulting from a stimulus-response association. Under this paradigm, understanding the nervous system is reduced to finding the relation between a sensory input and a motor output. Yet, in naturally behaving animals, motor actions influence sensory perceptions just as much as the other way around. Animals are continuously relying on sensory feedback to adjust motor commands. On the other hand, behavior is not only induced by the sensory environment, but can be generated by the brain's rich internal dynamics. My goal is to understand the sensory-motor dialogue by monitoring large brain regions, yet, with a single-neuron resolution. To tackle this question, I have used zebrafish larva to study visually induced and internally driven motor behaviors. Zebrafish larvae have a small and transparent body. These features enable using large-scale optical methods, such as selective plane illumination microscopy (SPIM), to record brain dynamics. In order to study goal-driven navigation in conditions compatible with imaging, I developed a visual virtual reality system for zebrafish larva. The visual feedback can be chosen to be similar to what the animal experiences in natural conditions. Alternatively, alteration of the visual feedback can be used to study how the brain adapts to perturbations. For this purpose, I first generated a library of free-swimming behaviors from which I learned the relationship between the trajectory of the larva and the shape of its tail. I then use this technique to infer the intended displacements of head-fixed larvae. The visual environment was updated accordingly. In the virtual environment, larvae were capable of maintaining the proper speed and orientation in the presence of whole-field motion and produced fine changes in orientation and position required to capture virtual preys. I demonstrate the sensitivity of larvae to visual feedback by updating the visual world only after the discrete swimming episodes. This feedback perturbation induced a decay in the performance of prey capture behavior, suggesting that larva rely on real-time visual feedback during swimming. Behavior can also be induced by the internal dynamics of the brain. In the absence of salient sensory cues, zebrafish larva spontaneously produces stereotypical tail movements, similar to those produced during goal-driven navigation. After having developed a new method to classify tail movements, I analyzed the sequence of spontaneously generated tail movements. The latter switched between period of quasi-rhythmic activity and long episodes of rest. Moreover, consecutive movements were more similar when executed at short time intervals (~10s). In order to study the mechanisms responsible for the spontaneous decisions to move, I coupled SPIM to tail movement analysis. Using dimensionality reduction, I identified clusters of neurons predicting the direction of spontaneous turn movements but not their timings. This Preliminary result suggests that distinct pathways could be responsible for the timing (when) and the selection (what) of spontaneous actions. Together, the results shed light on the role of feedback and internal dynamics in shaping behaviors and open the avenue for investigating complex sensorimotor process in simple systems

This doctoral thesis studies the unification of the category “disability” in France during the twentieth century. By unification, I mean the aggregation of various social groups under the term “disabled” accompanied by the development of institutions and practices increasingly specialized in the support of the disabled. This process also came about through the growth in the representation and knowledge on disabled persons as well as their increasing pres-ence in the public sphere. Based on archives, newspapers and other published material, audiovisual documents and personal interviews with key historical figures, this doctoral thesis analyses the numerous participants engaged in the representation of disabled peo-ple, establishes their position in this social field and identifies the issues at stake within it : establishing a definition of the category “disabled persons” and recommending what needs to be done, or not done, for the well-being of this segment of the population. The thesis brings into light the structural role of the activism lead by disabled students, who through-out the different stages of this field’s history have been suitably placed to subvert the domi-nant social order. The thesis also highlights the central role of epidemics such as tuberculo-sis and poliomyelitis in the empowerment of these people and examines the ways in which the social sciences contributed to distinguishing disabilities from illnesses. This thesis takes into account the transformation of the medical field and political arena when analyzing the constitution of the “disabled” category. Thus, this work develops a historical and political sociology of a social group which, while increasingly considered by the social sciences, has rarely been studied through a relational and process-oriented approach. In other words, analyzed as a field structured through by a power dynamics
