Utilisation de la couleur pour l'extraction de tableaux dans des images de documents

Tables are complex elements that can disturb the automatic analysis of the structure of an image of a document. In this article, we present a method based on the alternation of the color of lines to extract color tables that are not materialized by physical rulings. Experimental results, obtained on a dataset of document images with various layouts, enable to validate the interest of this appro...

Exploitation de la couleur pour la segmentation et l'analyse d'images. (Color image segmentation)

In this paper, we propose an original approach in order to improve the results of color im-age segmentation by pixel classification. We define a new kind of color space by selecting a setof color components which can belong to any of the different classical color spaces. Suchspaces, which have neither psycho-visual nor physical color significance, are named hybridcolor space...

Détection simultanée de l'ombre et de la végétation sur des images aériennes couleur en haute résolution

We propose a new method to simultaneously detect shadows and vegetation in remote sensing images. Several shadow and vegetation indices are merged with the Dempster-Shafer (DS) theory so as to increase the reliability and accuracy of the segmentation. The per-pixel DS fusion is incorporated in a Markovian context to obtain an optimal and regularized segmentation result. Evaluation on aerial ima...
