[Octave-bug-tracker] [bug #46124] image package: bwfill should use 4-connectivity as default

[Hartmut]

Follow-up Comment #3, bug #46124 (project octave):

I fully agree to NOT change this, because there is/was also a Matlab version
of bwfill. I didn't know of the existence of this old Matlab command bwfill,
it must have been removed from Matlab at least 10 years ago (before the R2006a
release, there is no older changelong on the Mathworks website). Here is some
old documentation of it:
http://www-rohan.sdsu.edu/doc/matlab/toolbox/images/bwfill.html .

So the real task would be to create an Octave version of IMFILL. Since imfill
does not only deal with binary images, but also with grayscale images and Nd
images, this task is too big for me to tackle it now.

How do you like the idea of creating a new m-file IMFILL.M for Octave, that
only acts as a compatibility wrapper for the existing bwfill.cc? Then the
Octave image package would have a Matlab compatible version of imfill, that
can at least deal with (2d) binary images (but not with grayscale or binary
images, yet). This smaller task might fit into my time budget. Let me know
your thoughts on this.
