Follow-up Comment #9, bug #56141 (project octave):

Looking in your examples in comment#7, I can't understand matlab behavior.

In the second example, all points have 2 neighbours, and all of removed, which
agrees with the initial algorithm, but in the first example, all the points
have 3, 5 or 8 neighbours, and only the one with 8 neighbours is removed.

In the example of comment#6, the only points that left are with 1 or 7
neighbours.

Also, in Matlab documentation it is written: "To find end points, the image
must be skeletonized". 
What does it mean? That in binary images which are not a result of a
skeletonization process the result does not have to be the endpoints?
