Interpolate black and white photos

[cybberle]

Dear owang, When I use your program to interpolate black and white photos, the program may encounter a bug. How can I solve this problem? Looking forward to your reply very much.

Easiest thing to do is just upconvert your grayscale images to rgb by replicating the channels before running the script. otherwise you probably need to change a couple of indices to make it work with single channel images.
