Urgent-Smoothing of an image-Fourier transform

[EDIT: 20110519 17:20 - inline image - WDR]

Hello,

The image below shows a regular paper surface. I want to use Fourier transform to find out the frequency components which are responsible for the texture on the surface. After i need to remove them to have a smooth surface without texture.could somebody help me please?

I just saw this. You can do this graphically, using some software such as FTL-SE (google it), which basically gives you a FFT of an image and you have some filters to play with. If you apply a low pas filter and adjust the radius of the filter you can get the surface to be smooth. The same idea applies otherwise.

A screenshot is below. The top is without filters, the bottom is with a low pass filter.
