Central Slice Theorem for 2 D FT Imnage

[Mathew]

DO anyone know how to apply 2D Central slice theorem for 2D Fourier Transformed Image? FOr this forst we need to mapp the samples of FT in Cartesian coordinate system to Polar.

Can anyone help with this?

Thanks

If you have Cartesian coords, you can transform to polar using Complex to Polar function from the following pallet:

Programming>Numeric>Complex

(Its polymorphic).

Hello N

I have found 2D FFT for an image. Now i need to compute the Central Slices for a particular value of (r,theta). This is what i need and not direct complex to polar conversion.

thankss
