We are working on something similar.
By the way, There use to be some links to Adobe Labs with articles of their engineers.
One of them was about the Oil Painter (Something about solving PDE's), try search for it, I will make easier to assist you.
Thank you for responding to my PhotoShop forum post.
By "working on something similar" do you mean you plan to release a plug-in I could purchase?
If the one you are developing would work as I need it to I would be happy to purchase yours.
Otherwise I am going to have to hire a developer to create one for me.
If yours isn't going to do what I need it to, but you can program one for me, I'd like to talk to you about it.
Specifically I need to apply Oil Paint filter effects — especially stylization and cleanliness — to large image files of around 100mb.
Hire a developer might cost a lot.
Those are advanced image processing algorithms, people who can do those stuff are paid a lot.
Let's start by finding those articles, Maybe someone from the Adobe team could direct us there.
I remember they a Russian engineer who is specialized with those Poisson and PDE's (Though if I remember correctly someone else wrote the specific article about Oil Painter algorithm).
You can see here what we do:
A product we're working on now deals with effects similar to what you're after.
If you want us to be specific (The Oil Painter), we can talk about it.
