Triangulation based graph models in color raster vectorization problem

During first vectorization stage, when individual liear segments of different colour lines are recognized automatically, as well as filled regions, we suggest building primary graph model on them, represented in the triangulation form. On it's base objects graph model is built interactively, consisting of two layers: the first layer is formed of filled regions and the second (top) layer consists of entirely recognized broken lines and contours. The applying of triangulation allows to build objects graph model by more time-effective algorithms and reduce occurence number of user interference into the algorithms functioning.
