[Octave-bug-tracker] [bug #60322] [octave forge] (image) imresize bicubic interpolation inaccurate

[Christof Kaufmann]

Follow-up Comment #9, bug #60322 (project octave):

Thanks for your comments.

* So, I found a quite recent thread
<https://octave.1599824.n4.nabble.com/Unit-tests-td4691577.html> about unit
testing local functions. So it is not really possible.

* I seem to have tested everything (partially implicitly) except the padding
function. I checked it manually, but I have to add a unit test for it.
Actually I can test it indirectly. I haven't thought about it before. So there
is no need for making it global.

* I will revert the demo changes. However, I think that RGB images are indeed
interpolated channel-wise. Just out of curiosity, what is the alternative from
your experience?

I prepared an updated patch (appended), so Avinoam does not need to look at
outdated code.
