Follow-up Comment #1, bug #50153 (project octave):

I have check all 2x2 logical matrices, and some 2x3 and 3x3, 
and it seems that bwperim is correct in all of them.
The only exception is 1x1, so what about a trivial check:


  if (numel(bw) == 1)
    perim = bw;
  else
    perim = (! imerode (bw, conn)) & bw;
  end
