Hi All,

I did FFT(Fast Fourier Transform) and and remove the 0 order from the FFT image and then apply IFT. Now I want to perfom Fresnel transform of that image.

Could you please share example code for me for the fresnel transform of an image?

Thank you Munish. Yes, actually I saw that work, but I dont understand where I will put my image? They did not work with any real image.
