Reconstruction of the surface of the Sun from stereoscopic images
Abstract This thesis concentrates on the stereoscopic reconstruction of environments containing transparent objects. The data used to test the algorithms is graciously provided by NASA through the STEREO mission. This thesis proposes a new spherical rectification technique as well as … Continue reading
Une approche globale à l’estimation du mouvement de caméra pour des scènes encombrées
This master’s thesis is a research in the field of computer vision and deals with egomotion estimation from a video sequence. Solving egomotion can lead to many applications, like automated navigation for instance. We analyse videos of cluttered scenes, composed … Continue reading

Reconnaisance de visages à partir de modèles tridimensionnels
Abstract This thesis concentrates on two aspects of three-dimensional face recognition: the correction of colors for several 3D scans and the process of face recognition by 3D alignment. When doing an acquisition with a structured-light scanner, we obtain the 3D … Continue reading

Construction d’une mosaïque à partir d’une séquence vidéo
Abstract In this thesis, we study the stages of the construction of an image mosaic, an important problem in the field of computer vision. First, we evaluate the existing methods, which deal with all the stages of construction of a … Continue reading
Estimation probabiliste du mouvement de caméra
Abstract This thesis presents a new approach for resolving a very important problem in computer vision, namely computing a camera ego-motion from a sequence of images. The ego-motion is defined as the 3D rotational and translational displacement undertaken by a … Continue reading
