[Octave-bug-tracker] [bug #54614] [octave forge] (image) wrong results of entropyfilt

[Hartmut]

Follow-up Comment #1, bug #54614 (project octave):

Please also have a look at file #39544 in my patch #9235 (and maybe bug #45088
as well). It deals with a bunch of filter functions at once, including
entropyfilt.m. This patch isn't perfect (the results aren't Matlab compatible,
yet), but it
* fixes the call to _spatial_filtering_.cc
* has a bunch of Matlab compatible tests for entropyfilt in it.

Some years ago, Carne didn't want to use this patch, because he preferred to
rather change the code of _spatial_filtering_.cc directly (if I remember
correctly). But neither of us has taken the time to rewrite my patch since
then...

Note: I haven't checked if this patch (i.e. only correcting the call to
_spatial_filtering_.cc inside of entropyfilt.m) improves the results on the
sample date in comment #0.
