Detecting waves on the water surface

I want to detect the wave pattern on the water surface and express it with a formula.
Since I can shoot videos, both image recognition and video methods are possible, but what should I do? ?

If the waves are standing waves and the situation involves light shining through relatively shallow water, then you might be able to to analyze the pattern of light and dark in still images to deduce the wave characteristics.
If that is not the situation you will probably need to analyze video.

Have a first look at the power of the 2-D Fourier-transform of your images. That might get you some sense of how wave-patterns in the image are distributed. You might need to undo the perspective-projection of your camera to get as sharp a spectrum as possible.
