2D Fourier Transform, Introduction

Cuthbert Nyack
The Fourier transform can be applied to 2 dimensional signals, eg images. The equations describing the 2D fourier transform is shown below. THe variables u and v are not the only ones used but they simplify the equations. u and v are equivalent to reciprocal wavelength (wave-number/(2 pi)).
