Details:
This happens with Octave 4.2.0 and the current image-2.6.1.
The result of this little script
BW = true;
P = bwperim(BW)
Q = bwperim(BW, 8)
returns twice a single 0 in Octave, but it returns twice a 1 in Matlab. The
Matlab result makes more sense to me, since even a 1x1 region DOES have a
perimeter, which is the pixel itself.
(I hit this when implementing a new feature for regionprops. But I will
probably work around this bwperim issue in regionprops, to not create too many
inter-dependencies of patches.)
