This announces the availability of a Wavelet Transform Library written in C++.
WAILI -- Wavelets with Integer Lifting
WAILI is a wavelet transform library. It includes some basic image
processing operations based on the use of wavelets and forms the
backbone of more complex image processing operations.
* Uses integer wavelet transforms based on the Lifting Scheme
* Provides various wavelet transforms of the
Cohen-Daubechies-Feauveau family of biorthogonal wavelets
* Provides crop and merge operations on wavelet-transformed images
* Provides noise reduction based on wavelet thresholding using
Generalized Cross Validation
* Provides scaling of images
* Provides edge enhancement of images
* Provides also some simple image operations (addition and
subtraction of images)
* Allows different image representations (RGB, YUV, Lab, ...)
The software library is written in C++ and extensively uses features
of the ANSI C++ 95 Draft Standard to allow for a cleaner design. The
development was done using GNU C++ 2.7.2.x.
WAILI is available in source form for research purposes only and may
not be further distributed. Enquiries about the license conditions
should be directed to firstname.lastname@example.org. Alternatively you

This library is developed within a project on Wavelet Based
Interactive Video Communication and Image Database Consulting, funded
by the Flemish Information Technology Action Program (Vlaams
Actieprogramma Informatietechnologie), project number ITA/950244.
