An image interpretation device can not be reliable without any semantic coherency analysis of the interpreted objects-application to French cadastral maps

The methodology we have used for the interpretation of French cadastral documents focuses on a number of studied results of the visual perception and a hierarchical description of the document. The strategy used has been based on the "model" document, employing a mixed approach including various "points of view" about the image to be processed. The results of this mixed analysis reveal the appearance of noninterpretable objects on the cadaster, due to the presence of semantic uncoherence. Thanks to the return cycles between the high and low level processing, an analytical strategy is proposed to independently cure the incoherence, thus to attain the most reliable interpretation of the cadastral map.
