Ouwayed, Nazih. "Segmentation en lignes de documents anciens : applications aux documents arabes". Thesis, Nancy 2, 2010. http://www.theses.fr/2010NAN23001/document.
Texto completoThe indexing of handwritten scanned documents poses the problem of lines segmentation, if it fails, disabling the following steps of words extraction and recognition. In addition, the ancient Arabic documents contain annotations in the margins, often composed of lines obliquely oriented. The detection of these lines is important as the rest and is a major challenge for the indexing of these documents. Thus, the segmentation described in this thesis involves the extraction of multi-oriented lines. For this problem, the bibliography has only rudimentary techniques based essentially on the projection of the document image along one direction, which be failed in the case of multi-oriented documents. Given this lack, we have proposed an adaptive approach that first locates the different orientation zones, then based on each local orientation to extract the lines. During my thesis, i particularly invested on the following points : - Applying an automatic paving using the active contour model (snake). - Preparation the signal of the projection profile by removing all pixels that are not needed in the orientation estimation. Then, implementation of all energy distributions of Cohen's class on the projection profile to find the best distribution that gives the orientation. - Applying some extension rules to find the oriented zones. - Extraction of lines by using an connected components follow-up algorithm. - Separation of overlapped and touched lines using the morphology of Arabic terminal letters

Texto completoLa ligne de partage des eaux topologique (LPE) étend la notion de clivage aux graphes dont les sommets sont valués et permet de segmenter une image. Nous étendons les propriétés des clivages dans les graphes de fusion aux cas des fonctions et proposons un algorithme de LPE
monotone et linéaire dans les grilles de fusion parfaites. Grâce à la notion de graphe d'arêtes, les propriétés des LPE dans les grilles de fusion parfaites s'étendent aux graphes à arêtes valuées.
Nous étudions en profondeur les LPE dans les graphes à arêtes valuées. Les LPE peuvent y être définies en suivant l'idée intuitive de gouttes d'eau s'écoulant sur un relief topographique. Nous établissons aussi bien la consistance que l'optimalité de cette définition. De plus, nous proposons deux algorithmes linéaires qui, à notre connaissance, sont les plus efficaces pour le calcul des LPE.
En nous reposant sur ces résultats théoriques, nous proposons une méthode et développons un logiciel pour la segmentation du ventricule gauche dans des images cardiaques 3D+t par résonance magnétique. La méthode est quantitativement et qualitativement validée par comparaison avec des segmentations manuelles tracées par deux experts cardiologues.

Texto completoNowadays, image processing remains a very important step in different fields of applications. In an indoor environment, for a navigation system related to a mobile robot (electrical wheelchair), visual information detection and tracking is crucial to perform robotic tasks (localization, planning…). In particular, when considering passing door task, it is essential to be able to detect and track automatically all the doors that belong to the environment. Door detection is not an obvious task: the variations related to the door status (open or closed), their appearance (e.g. same color as the walls) and their relative position to the camera have influence on the results. On the other hand, tasks such as the detection of navigable areas or obstacle avoidance may involve a dedicated semantic representation to interpret the content of the scene. Segmentation techniques are then used to extract pseudosemantic regions based on several criteria (color, gradient, texture...). When adding the temporal dimension, the regions are tracked then using spatiotemporal segmentation algorithms. In this thesis, we first present joint door detection and tracking technique in a corridor environment: based on dedicated geometrical features, the proposed solution offers interesting results. Then, we present an original joint hierarchical and multiresolution segmentation framework able to extract a pseudo-semantic region representation. Finally, this technique is extended to video sequences to allow the tracking of regions along image sequences. Based on contour motion extraction, this solution has shown relevant results that can be successfully applied to corridor videos
