Elliptic-cylinder Wavelets
This is a wide family of wavelet system that provides a multiresolution analysis. The magnitude of the detail and smoothing filters corresponds to first-kind Mathieu functions with odd characteristic exponent. The number of notches of these filters can be easily designed by choosing the characteristic exponent. Elliptic-cylinder wavelets derived by this method possess potential application in the fields of optics and electromagnetism due to its symmetry.

Famous quotes containing the word wavelets:
“Broken by great waves,
the wavelets flung it here,
this sea-gliding creature,
this strange creature like a weed....”
