- f(x,y) is the input image,
- g(x,y) is the processed image,
- h(x,y) is a linear, position invariant operator
(a position invariant operator is one whose result depends only on the value of f(x,y) at a point in the image and not on the position of the point)
- G, H, and F are the Fourier transforms of g, h, and f, respectively
- H(u,v) is the transfer function
- h(x, y) is called the impulse response (point spread function).
