How can I remove the texture from an image using matlab?

问题

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.

This is the image.

Thanks

If you use Fourier Transform and analyze frequency components, then removing high frequency components of the image gives a close effect of low pass filter. However, it does not seem natural since you also manipulate the phase of the image. As people suggest, I also advise low pass filter. More specifically, if you want the color of the given image, you may want to try Gaussian Filter.
