A number of wavelets with different properties, including several ``Bathlet'' orthonormal wavelets [10], biorthogonal wavelets [11], ``Coiflets'' [12], Daubechie's wavelets [13], UCLA wavelets [14], and the FBI fingerprint wavelet used for compressing fingerprint images [15] are automatically installed in /usr/local/lib/wavelets. The default search path can be customized for each user by editing the .tnimage file.
If the Laplacian algorithm is used, selecting a wavelet is not necessary. The Laplacian algorithm uses the specified binomial filter length.
