[scikit-image] Perimeter and neighborhood

I played around with the perimeter from skimage.measure. In the documentation, the neighborhood is described as: "neighbourhood : 4 or 8, optional Neighborhood connectivity for border pixel determination." There is an imprecision because this is different from the connectivity of the resulting contour. If N4 is chosen, then the contour is 8-connected, and conversely. The documentation could have this precision. yann -- Yann GAVET Assistant Professor - Ecole Nationale Supérieure des Mines de Saint-Etienne 158 Cours Fauriel, CS 62362, 42023 SAINT-ETIENNE cedex 2 Tel: (33) - 4 7742 0170
