Une littérature du décloisonnement : la construction de la figure de l'écrivain et du littéraire dans Comment faire l'amour avec un Nègre sans se fatiguer et Cette grenade dans la main du jeune Nègre est-elle une arme ou un fruit? de Dany Laferrière

Dany Laferrière, récemment admis à la prestigieuse Académie française, a produit une œuvre considérable au cours des trente dernières années. Deux de ces premiers romans, Comment faire l’amour avec un Nègre sans se fatiguer et Cette grenade dans la main du jeune Nègre est-elle une arme ou un fruit?, sont caractérisés par une intertextualité riche et variée. La trame narrative de ces deux romans est construite par fragments. Dans le premier texte, on retrouve un écrivain fictif qui procède à l’écriture d’un roman qu’il nomme Paradis du dragueur nègre. Dans le deuxième roman, nous retrouvons le même écrivain, mais ce dernier est plutôt employé par un magazine de la côte est afin de rédiger un reportage sur l’Amérique. Dans les deux cas, il y a une mise en scène de l’écriture par un écrivain fictif qui présente beaucoup de ressemblances avec Laferrière lui-même. Le lecteur assiste à la construction du récit qu’il est en train de lire à travers une autofiction originale. Il y a donc une multitude de ressemblances, et mêmes correspondances, entre les deux récits. Les deux romans de Laferrière s’inscrivent par leur thème, leur style et leur genre dans une « généalogie » de textes qui peuvent être regroupés en « familles » littéraires. Nous tenterons, dans le mémoire qui suit, de définir et de comprendre le rôle de ces « familles » et d’illustrer comment l’appropriation de ces textes permet à l’auteur à la fois de s’en inspirer et de s’en distancer. Il s’agira donc, dans les deux premiers chapitres, d’étudier les références intertextuelles appartenant à ces deux « familles » d’écrivains pour ensuite étudier plus particulièrement la construction de la figure de l’écrivain et de son espace littéraire à travers ces deux œuvres. MOT-CLÉS : Dany Laferrière ; intertextualité ; autofiction ; roman contemporain ; littérature québécoise.

Dibutade 2.0 : la "femme-auteur" à l'ère du numérique

Prenant le parti d’étudier la culture numérique émergente selon des rapports de continuité plutôt que de rupture, cet article envisage la question de l’auctorialité féminine sur le web au regard du mythe antique de Dibutade. Il semble en effet que Dibutade, en sa qualité de figure fondatrice de nombreuses pratiques artistiques, nous permet de porter un éclairage tout à fait intéressant sur la façon dont certaines bloggeuses affirment leur statut de femme auteur, jouant rôle majeur et moteur dans l’émergence et la reconnaissance d’une littérature numérique (conçue en ligne, publiée en ligne). Les analyses conduites dans cet article entendent souligner le potentiel esthétique de certaines pratiques d’écriture en ligne souvent ignorées par les études littéraires : les profils Facebook, les blogues érotiques voire pornographiques.

Pertormer’s Rights in India

The overall focus of the thesis involves the performer's rights in india -A study with special reference to the audiovisual industry.The performer is the disseminator of works of literary, dramatic artistic and musical authorship .The challenge of studying the audiovisual industry is the low level of data documentation and transparency in transactions compounded by the low awareness of legal issues. The first five chapters of the study trace the evolution of performers’ rights with particular impetus on three diverse jurisdictions both at the judicial and statutory levels as well as from the collective bargaining platform.The study also seeks to pin point the major obstacles that the performers have had to encounter in their quest for equal rights under the umbrella of intellectual property the world over.the status of the performer through the international instruments - the Rome convention, the WPPT and the envisaged Protocol to the audiovisual performance.A grant of rights to the performer either under Copyright or labor law need not improve matters for the performer unless the institutional grievance redressal is firmly put in place.There is a need for clearer delineation between the definitions of audio and audiovisual fixations. Under the Indian law the terms representing these have been sound records and cinematographs respectivel.Performer and the Philosophy of Intellectual Propertyeffectively. But this is not to deny the fact that these institutions, organizations and practices could very well rise to the occasion when the rights regime comes into force.

Extracting Urban Food Potential: design-based methods for digital and bodily cartography

Sweden’s recent report on Urban Sustainable Development calls out a missing link between the urban design process and citizens. This paper investigates if engaging citizens as design agents by providing a platform for alternate participation can bridge this gap, through the transfer of spatial agency and new modes of critical cartography. To assess whether this is the case, the approaches are applied to Stockholm’s urban agriculture movement in a staged intervention. The aim of the intervention was to engage citizens in locating existing and potential places for growing food and in gathering information from these sites to inform design in urban agriculture. The design-based methodologies incorporated digital and bodily interfaces for this cartography to take place. The Urban CoMapper, a smartphone digital app, captured real-time perspectives through crowd-sourced mapping. In the bodily cartography, participant’s used their bodies to trace the site and reveal their sensorial perceptions. The data gathered from these approaches gave way to a mode of artistic research for exploring urban agriculture, along with inviting artists to be engaged in the dialogues. In sum, results showed that a combination of digital and bodily approaches was necessary for a critical cartography if we want to engage citizens holistically into the urban design process as spatial agents informing urban policy. Such methodologies formed a reflective interrogation and encouraged a new intimacy with nature, in this instance, one that can transform our urban conduct by questioning our eating habits: where we get our food from and how we eat it seasonally.

Model-Based Matching by Linear Combinations of Prototypes

We describe a method for modeling object classes (such as faces) using 2D example images and an algorithm for matching a model to a novel image. The object class models are "learned'' from example images that we call prototypes. In addition to the images, the pixelwise correspondences between a reference prototype and each of the other prototypes must also be provided. Thus a model consists of a linear combination of prototypical shapes and textures. A stochastic gradient descent algorithm is used to match a model to a novel image by minimizing the error between the model and the novel image. Example models are shown as well as example matches to novel images. The robustness of the matching algorithm is also evaluated. The technique can be used for a number of applications including the computation of correspondence between novel images of a certain known class, object recognition, image synthesis and image compression.

Model-Based Matching of Line Drawings by Linear Combinations of Prototypes

We describe a technique for finding pixelwise correspondences between two images by using models of objects of the same class to guide the search. The object models are 'learned' from example images (also called prototypes) of an object class. The models consist of a linear combination ofsprototypes. The flow fields giving pixelwise correspondences between a base prototype and each of the other prototypes must be given. A novel image of an object of the same class is matched to a model by minimizing an error between the novel image and the current guess for the closest modelsimage. Currently, the algorithm applies to line drawings of objects. An extension to real grey level images is discussed.

Matching Interest Points Using Projective Invariant Concentric Circles

We present a new method to perform reliable matching between different images. This method exploits a projective invariant property between concentric circles and the corresponding projected ellipses to find complete region correspondences centered on interest points. The method matches interest points allowing for a full perspective transformation and exploiting all the available luminance information in the regions. Experiments have been conducted on many different data sets to compare our approach to SIFT local descriptors. The results show the new method offers increased robustness to partial visibility, object rotation in depth, and viewpoint angle change.

Estimating the motion of an underwater robot from a monocular image sequence

When underwater vehicles perform navigation close to the ocean floor, computer vision techniques can be applied to obtain quite accurate motion estimates. The most crucial step in the vision-based estimation of the vehicle motion consists on detecting matchings between image pairs. Here we propose the extensive use of texture analysis as a tool to ameliorate the correspondence problem in underwater images. Once a robust set of correspondences has been found, the three-dimensional motion of the vehicle can be computed with respect to the bed of the sea. Finally, motion estimates allow the construction of a map that could aid to the navigation of the robot

VLSI architecture for an Underwater Robot Vision System

It is well known that image processing requires a huge amount of computation, mainly at low level processing where the algorithms are dealing with a great number of data-pixel. One of the solutions to estimate motions involves detection of the correspondences between two images. For normalised correlation criteria, previous experiments shown that the result is not altered in presence of nonuniform illumination. Usually, hardware for motion estimation has been limited to simple correlation criteria. The main goal of this paper is to propose a VLSI architecture for motion estimation using a matching criteria more complex than Sum of Absolute Differences (SAD) criteria. Today hardware devices provide many facilities for the integration of more and more complex designs as well as the possibility to easily communicate with general purpose processors

Proposal of a parallel architecture for a motion detection algorithm

This paper proposes a parallel architecture for estimation of the motion of an underwater robot. It is well known that image processing requires a huge amount of computation, mainly at low-level processing where the algorithms are dealing with a great number of data. In a motion estimation algorithm, correspondences between two images have to be solved at the low level. In the underwater imaging, normalised correlation can be a solution in the presence of non-uniform illumination. Due to its regular processing scheme, parallel implementation of the correspondence problem can be an adequate approach to reduce the computation time. Taking into consideration the complexity of the normalised correlation criteria, a new approach using parallel organisation of every processor from the architecture is proposed

Surface registration from range image fusion

The registration of full 3-D models is an important task in computer vision. Range finders only reconstruct a partial view of the object. Many authors have proposed several techniques to register 3D surfaces from multiple views in which there are basically two aspects to consider. First, poor registration in which some sort of correspondences are established. Second, accurate registration in order to obtain a better solution. A survey of the most common techniques is presented and includes experimental results of some of them

A new optimised De Bruijn coding strategy for structured light patterns

Coded structured light is an optical technique based on active stereovision that obtains the shape of objects. One shot techniques are based on projecting a unique light pattern with an LCD projector so that grabbing an image with a camera, a large number of correspondences can be obtained. Then, a 3D reconstruction of the illuminated object can be recovered by means of triangulation. The most used strategy to encode one-shot patterns is based on De Bruijn sequences. In This work a new way to design patterns using this type of sequences is presented. The new coding strategy minimises the number of required colours and maximises both the resolution and the accuracy

Overview of coded light projection techniques for automatic 3D profiling

Obtaining automatic 3D profile of objects is one of the most important issues in computer vision. With this information, a large number of applications become feasible: from visual inspection of industrial parts to 3D reconstruction of the environment for mobile robots. In order to achieve 3D data, range finders can be used. Coded structured light approach is one of the most widely used techniques to retrieve 3D information of an unknown surface. An overview of the existing techniques as well as a new classification of patterns for structured light sensors is presented. This kind of systems belong to the group of active triangulation method, which are based on projecting a light pattern and imaging the illuminated scene from one or more points of view. Since the patterns are coded, correspondences between points of the image(s) and points of the projected pattern can be easily found. Once correspondences are found, a classical triangulation strategy between camera(s) and projector device leads to the reconstruction of the surface. Advantages and constraints of the different patterns are discussed

Availability analysis of GMPLS connections based on physical network topology

This paper presents a study of connection availability in GMPLS over optical transport networks (OTN) taking into account different network topologies. Two basic path protection schemes are considered and compared with the no protection case. The selected topologies are heterogeneous in geographic coverage, network diameter, link lengths, and average node degree. Connection availability is also computed considering the reliability data of physical components and a well-known network availability model. Results show several correspondences between suitable path protection algorithms and several network topology characteristics
