How can I use the fourier transform to find out the frequency components which are responsible for the texture on the surface?
Then I have to remove them to have a smooth surface without texture.
you can see the image in the following link:
Thanks in advance

In one of your duplicate posts, which I have now deleted, Image Analyst commented,
'Like I said in a comment on one of your other numerous posts on this subject: "Jim, you've got to stop the duplicate posts. You do this frequently, and then people like Wayne waste their time telling you how to do a high pass filter when I've already told you that a high pass filter is not the way to go."'

Take the 2D FFT. Look for spikes in the 2D FFT and zero them out. Inverse transform and display.

I tried experimenting around with some values and that's just what worked the best.
