Can this algorithm used to fuse two images?

[joey0922]

I used differential diffusion to do some experiment, and I turned out wonderful! But I am wondering if differential diffusion is able to fuse two images. I have a background image containing a object and background, a foreground image containing an object with transparent background and a mask of foreground. How can I take use of diffienertial diffusion to do this task? I noticed there are two parameters named original_image and image, I used them to do some testing and it didn't work out. Did I do it in a wrong way? Whether is diffierential diffusion able to accomplish this task?
