[Octave-bug-tracker] [bug #55790] [octave forge] (image) stdfilt throws error "__spatial_filtering__: A should be real or logical"

[Joel Cottrell]

Follow-up Comment #3, bug #55790 (project octave):

Thanks Avinoam, I imagine that would enable the stdfilt function to run
without errors and produce a sensible output.

But from looking inside the C code, it seems like the __spatial_filtering__
function is meant to work for integer data types, and has done so in previous
versions, perhaps with performance benefits over floating point.

Might it be possible to remove or fix the checks that cause this error message
for integer input, so that it's not necessary to cast to double at the higher
level?
