Re: [Algorithms] lens blur (or Bokeh filter)

Vincent Scheib posted some interesting thoughts on depth of field effects:

As he points out Lost Planet has done a good job reproducing this effect, using a somewhat unconventional composition method:

Nick Porcino describes it as well:

I'd just get your standard Depth of field functions working, then change the blurring stage. It does seem that the only real difference is that intead of being a gaussian blur, it's just a case of a shape blur. If you can follow a depth of fielf "howto", then you should be able to adjust the final result quite simply.

Hi,
I'm trying to find out how lens blur algorithm is working. For example
it is implemented in Photoshop:
http://www.computer-darkroom.com/tutorials/tutorial_9_1.htm
it's also known as Bokeh effect:
http://en.wikipedia.org/wiki/Bokeh

Does anyone know how can I implement this algorithm? Any links will be
highly appreciated. Failed to find anything useful in google.

Thanks in advance.

Just because the world is full of people that think just like you, doesn't mean the other ones can't be right.
