Full textNowadays, in addition to the classical domain of the robotic manipulation, vision-based control offers a large spectrum of applications in various contexts using computer vision and control theory. One possibility to develop vision-based control algorithms is to integrate methods and approaches developed in a separately by the vision and the control communities. Instead of considering vision and control techniques separately, in this thesis, they are integrated in a unified framework. We developed a generic, flexible and robust system that can be used by a wide variety of robotic applications. We made different contributions towards the conception of such complete system. Two major contributions are presented:1- A template-based visual tracking of objects in the image using an Efficient Second-order Minimization technique called the ESM technique. Compared to the existing methods, the proposed algorithm gives better convergence properties (bigger radius and higher rate and frequency of convergence). This approach has been generalized to the direct estimation in the Cartesian space of the relative camera/object motion. 2- A new 2D visual servoing is also introduced. The control law is locally stable and unlike all the existing methods, it does not need any a priori measure of the model of object with respect to which the visual servoing is performed. Only information extracted from the reference and the current images are used to compute the control law

Full textThe existing 3D sensors aren’t much used and are only capable of capturing 3D dat. When 2D data are necessary, one has to use another camera and correlate the 2 images. NT2I has decided to develop its own solution in order to control the acquisition chain. My work has been to develop a specific camera with color, calibration, and image processing algorithms. In that purpose, I've worked on the extension of the LIP model (Logarithmic Image Processing) for color images and on the implementation of real time algorithms

Full textThe image processing methods based on Partial Differetial Equations (PDEs) draw a groving attention of the scientific community. The number of applications has increased with the introduction of the Level Set methods. The EDPs apply in many domains such the image improvement, the segmentation by active contours usedboth for static pictures and image sequences or recent methods such as shape-from-shading. The industrial applications of these methods remain limited due to a computation complexity on one hand, and the difficulties of embedded system implementation (energy consumption, memory requirements) on the other hand. Our goal is to propose a dedicated architecture facilitating the implementation of a realtime embedded system. Regarding this objective, we propose a new algorithm Massive Marching solving the Eikonal equation for computation of the distance function. It proceeds in parallel and eliminates the usage of the ordered data structures. It allows to obtain the solution either on the entire image or only on its part : the Narrow Band around the propagation front. The complexity of Massive Marching is linear. The Massive Marching represents the algorithm allowing to obtain the watershed in parallel. Next, we propose two architecture types (i) SIMD and (ii) MIMD, based on several embedded processor cores, implementing Massive Marching in parallel or semi-parallèle. The same architecture types can be used to implement filtering algorithms as well as methods of interface evolution. The same architecture can therefore be used to implement all the steps of a complete application consisting of different types of algorithms, e. G. Filtering followed by segmentation

Full textIn computer graphics, we distinguish modeling from rendering, that is image synthesis. This thesis framework is real-time rendering of scene composed of complex non deformable 3D objects. Such objects gives high realism in computed images but are difficult to use (in terms of storage space and computing time). A lot of works as been driven in this context. We first describe commonly used approach that is point sample rendering, geometrical mesh simplification and image-based rendering. We first propose different algorithms to extend image based methods to real-time rendering. We then describe a method to generate 4D textures producing image of a given 3D object from arbitrary viewpoint, independently of its geometrical complexity. Finally, we present an image interpolation method to map relief onto a given depth image or a low polygon count version of a complex object. This works intensively use latest GPU capabilities, allowing high quality and real-time rendering at same time

Full textIn the context of real-time image synthesis, this thesis investigate the use of points as a display primitve. We propose a complete rendering pipeline of point-based geometries which has the particularity to maintain a very high rendering quality both in case of under-sampled or over-sampled models while maintaining real-time performances. To reach these goals, we present both an adaptation of the surface splatting algorithm to modern graphics cards, and a new technique called deferred splatting which defers filtering operations in order to perform them on visible points only. Finally, in similar fashion to subdivision surfaces for polygonal meshes, we proposed an interpolatory refinement framework allowing to dynamically reconstruct a smooth surface from a scattered and/or under-sampled point based model
