Remove paper texture pattern from a photograph

I've scanned an old photo with paper texture pattern and I would like to remove the texture as much as possible without lowering the image quality. Is there a way, probably using Image Processing toolbox in MATLAB?

I've tried to apply FFT transformation (using Photoshop plugin), but I couldn't find any clear white spots to be paint over. Probably the pattern is not so regular for this method?

You can see the sample below. If you need the full image I can upload it somewhere. photograph sample

Well i have tried out a different approach using Anisotropc diffusion using the 2nd coefficient that operates on wider areas

Here is the output i got:

From what i can See from the Picture, the Noise has a relatively high Frequency Compared to the image itself. So applying a low Pass filter should work. Have a look at the Power spectrum abs(fft(...)) to determine the cutoff Frequency.
