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

[Carnë Draug]

Follow-up Comment #3, bug #54614 (project octave):

> Another problem is in the transfer of data from the matrix:
It seems that the line [...] is wrong [...]

That line adds the height value to each element. Some functions call
__spatial_filtering__ with a value there (but I think in most cases it will be
zero).

Do you have a case where that line is causing incorrect values? If the test
suite did not fail when you removed it, I guess we should add a case for it.
For example:


octave:7> ordfiltn([1 2 3 4], 1, [1 1 1], [0 0 0]) # this is default height
(S)
ans =

   0   1   2   0

octave:8> ordfiltn([1 2 3 4], 1, [1 1 1], [2 1 0])
ans =

   2   3   4   0
