are u asking abt the wavelets in image processing?

Newton postulated that light was particles because of the hature of his observations of it (shadows being cast etc.)
Huygens developed a wavelet theory of light to explain refraction, relection and diffraction
"In 1678 the great Dutch physicist Christian Huygens (1629-1695) wrote a treatise called Traite de la Lumiere on the wave theory of light, and in this work he stated that the wavefront of a propagating wave of light at any instant conforms to the envelope of spherical wavelets emanating from every point on the wavefront at the prior instant (with the understanding that the wavelets have the same speed as the overall wave)" See http://www.mathpages.com/home/kmath242/kmath242.htm

a man wave and a lady wave gets together... have a few drinks....
bingo...
loads of tiny little wavelets!

You are probably familiar with Fourier analysis, where you can represent a function as a combination of sine and cosine waves of different frequencies. So it turns out, you can do this with other functions besides sines and cosines - and that's the basics of wavelets.
Hubbard's book (link below) is really good introduction to wavelets.
