Does anybody know if it is possible to represent image data as a sine wave?

More info is needed. I can represent an image by a lot of sine waves - that's what its Fourier transform is.

Thanks, I've been looking at using the output of FFT and I think it's a good way to go. Do you know how I can use the stepinfo() function on the image data, such that it can tell me the overshoot, undershoot and settling time? The document says that the input data must be a Transfer Function, but I am not sure how to compute this from the spatial pixel values...
