Details:

Here is a little script to show the behavior (image 2.4.0 under Octave
4.0.0-rc4):


pkg load image
I = ones(10);
J = rangefilt(I);


The result is an error message. I think this is only due  to incorrect input
checks in rangefilt.m . I will attach a patch to correct this.

But it might be worth to check all other functions in the image package for
this same type of bug!
