Hi,
I found a bug in imfilter in the image package.
I first tried to search bug reports about this, but I couldn't find it, so
I post it here.
imfilter in the image package works in the opposite way it's supposed to do.
When I do "imfilter(1:5, [0 -1 1], 'corr', 'circular')', I get the results
below
imfilter(1:5, [0 -1 1], 'corr', 'circular')
4 -1 -1 -1 -1
But the correlation operation should result in
1 1 1 1 -4
I also tested the same function 'imfilter' in Matlab, and it gives me the
right answer.
Thanks,
Sunghyun
p.s. This is my first time to post to this mailing list, so I'm still not
sure if this is the right place for this kind of bug reporting. If not,
please let me know.
