                         recognition of scanned isovalues maps. It includes pre-processing, 
                         thinning and vectorization of bilevel images. Following these 
                         three steps, the separation of different graphics elements and its 
                         recognition are presented. Finally some results concerning the 
                         implementation are considered.",
