Most filtering functions in the image package currently only support
grayscale images (no color images), at least when using this simple syntax.
There is a workaround explained here:
https://savannah.gnu.org/bugs/?45088#comment1
It is explained for rangefilt, but this workaround should also work for
medfilt2:
filtered = medfilt2 (noise_image, logical(padarray (ones (3), [0 0 1])));
At some time, this behavior might be fixed eventually in the Octave image
package.
The function imshowpair is currently not implemented in the image package.
Try
figure, imshow(im)
figure, imshow(noise_image)
instead.
Good luck
Hartmut
