A method for segmenting elements on an image, comprising: i) creating an active contour from at least one identified point on the image; ii) defining a reference intensity value from the pixels of the active contour; iii) simplifying the image by comparing the pixels of the image to the reference intensity value to give a propagation value to the pixels of the image; and iv) propagating the active contour in a selected one of an expansion/contraction direction as a function of the propagation value of the pixels adjacent to the active contour in the image; wherein ii), iii) and iv) are repeated in the selected direction whereby the active contour finally represents the element segmented in the image.
