French map interpretation: a sound approach

The aim of the interpretation of documents is to extract as automatically as possible their characteristic elements in order to store them as object instead of pixel. This paper deals with a cadastral map interpretation device. Our approach to solve this problem is two fold: 1) it vectorizes the image by extracting the lowest information level; and 2) using the low level primitives and introducing the a priori knowledge of the cadastral map, it reconstructs real cadastral entities. First, we present different original tools to allow one to extract the low level primitives. Then, we present the strategy which is used to perform the interpretation stage.<
