I think there was a concern about the directionality of the scipy.ndimage implementation. Maybe we can modify the version in the scikit to make use of the scipy.ndimage one, but to compute the horizontal, vertical and averaged sobels?
Looking at this further, I am not happy with the result of either scikits.image or scipy.ndimage: http://mentat.za.net/refer/sobel.jpg Compare this, e.g., to the wikipedia page here: http://en.wikipedia.org/wiki/Sobel_operator Stéfan
