Automatic interpretation of scanned maps: Reconstruction of Contour Lines,nized end vectorized. Then, by a local analysis, we weight and add some hypothetical edges. By a relaxation process, we try to orientate the elevation curves, and so we could re-adjust the weight. Finally, we found a topologycally correct solution by resolving the dual problem (i.e. a bi-colouring problem).

Segmentation of thematic maps using colour and spatial attributes,d on the Delaunay triangulation. It enables to spatially define textured regions by analyzing the spatial relationship between neighbouring pixels, not necessary adjacent. Examples illustrate the different steps of the segmentation procedure.

We present detailed algorithms for recognizing these graphic objects, which are all based on the same generic recognition algorithm.

As part of this discussion we elaborate on the knowledge representation and the interpretation mechanism, propose a new concept to handle multiple detectors, introduce a new judgment procedure of instances of map objects and show the necessity of explicitly specified conflict rules.

Improved directional morphological operations for separation of characters from maps/graphics,ch to improve the efficiency of this algorithm using run-length-encoded (RLE) image representation. Directional edge images are all represented as directional run-length linked lists. Moreover, we migrate all of the processes used to the RLE data structure. As a result, we reduce significantly both
