Hi Cory,<br><br>I have a 3D OCT scan and I want to reduce the noise. I want to use the Wiener filter because I have a paper here where they used it and I want to check if I get similar results. In the paper they say they used a 10x10 Wiener filter (it was a 2D OCT scan). I guess they used wiener2 in Matlab.<br>

What kind of image do you have? What are you trying to accomplish with<br>
the Wiener filter?<br>
