[Octave-bug-tracker] [bug #51884] [octave forge] (image) bwmorph(blackNwhiteMatrix, "thicken", 1) returns negated result (+ strange behavior at border)

[Avinoam Kalma]

Follow-up Comment #14, bug #51884 (project octave):

Tried a simple example:


H = false (5,5);
H(3,3) = 1;
a = bwmorph(H,'thicken', 1)

Matlab:

a =

  5×5 logical array

   0   1   1   1   0
   1   1   1   1   1
   1   1   1   1   1
   1   1   1   1   1
   0   1   1   1   0


Octave:

a =

  0  0  0  0  0
  0  0  1  0  0
  0  1  1  1  0
  0  0  1  0  0
  0  0  0  0  0


BTW, what is the mathematical definition of 'thicken'?
