Error with anisotropic diffusion script

I tried to use the attached 'anisotropic diffusion' script but it gives me an error that it does not work on 3d image. I wonder if anyone has an updated script to work on the attached example image.

The great majority of gray-looking jpg images are actually rgb images.

• you could take special steps to convert to a true grayscale jpg image
• you could convert the image to grayscale and write it as png or other format that is more suitable for grayscale
• you could rgb2gray the image after reading it in
• you could go back to the original dicom data and write it as png
