[Numpy-discussion] Bilateral filter

As much as I know, the python's community is bound to the BSD style licence. I was hoping that the code would be included in scipy, after I would attach the required declaration (I do not know which), and maybe with some adjustment to the coding style.

In short, for the next few days I am waiting for comments and responses that would enable me to donate the code to an existing project (scipy? pyvision?). Meanwhile I'll improve the co a bit. If you can't wait, and not willing to use the code without a licence statement, I'll repost the code with the scipy's licence declaration.

  Nadav.

Thanks for the code! I know it will be of use to me. (Do you place any  
particular license on it?)
