Blemish Removal in Digital Image
I'm currently writing an image editing application using Flex and I'm trying to make a blemish removal functionality like in picnik.com. 

I have searched everywhere but couldn't find anything. 
What is the best way that's suitable for this?

I have tried to just blur away the blemishes, but the results are bad.
