Automatic segmentation of Cassini's maps



Our goal is to segment ancient maps of France, being cut and glued on a canvas. The colors in the canvas and in the maps are very close, making the boundary difficult to distinguish. However, pixel-perfect parts of the boundary are obtained thanks to morphological operators. To complete the segmentation, the image is separated, thanks to a maskinto three zones (map, canvas, and a "thick" boundary)which are used by a classification method to obtain results close to the actual boundary. Finally, the first results are corrected thanks to such new knowledge.
