Abstract : In this article we present a two dimensional edge extractor which gives the edge position in an image with a subpixelic precision. The method presented here gives a good accuracy with a low computational cost, and its implementation is very simple since it is derivated from the well-known Non-Maxima Suppression method [I, 3]. We also justify the method by showing that it gives the exact result in a theoretical one dimensional example. We have tested the edge extractor on several synthetical and real images and the results are reported in this paper.
