Title: DOC: reference broken,  protect last character in URL

See ref in http://scikit-image.org/docs/dev/api/skimage.filter.rank.html#entropy

According to
http://docutils.sourceforge.net/docs/ref/rst/restructuredtext.html#id76
the addition of a '>' character at the end is a solution. (I checked, it works).
