A More Controllable Anisotropic Diffusion?

"maria" wrote in message

I need to have various grades of anisotropic diffusion for my work. There is only one such grade in CS2. Does anyone know of any plugin or action that I can use for such an effect?
Or, better, does anyone know another combination of CS2-filters that achieves anisotropic diffusion with a bit of control on it?

Your question is a bit specialized. Can you be more specific about your application?

Mike,

Anisotropic diffusion is a denoising image process. I usually apply it after I sharpen an image in order to achieve a certain intermediate denoising effect. I need a filter that applies the process in various degrees of strength/intensity. Richard Rosenman has such a filter, but I don’t seem to be able to get what I want from it.
Thanks!

I notice there hasn’t been a response, so here are a couple of thoughts on how Photoshop might help:

1) duplicate the layer in Photoshop, apply the anisotropic filter to the new layer, and adjust the transparency of the layer.
2) you may be able to get various changes in intensity by changing the mode of the new layer to color, to remove chroma noise.

An additional thought for Maria: have you tried Neat Image, or the other main de-noising program (name eludes me right now, but it’s 4:00AM and I have only had one cup of coffee)? NI has an extreme array of controls and might might do some, or all of what you want.
