a cross-platform discrete wavelettransform library implemented in C
libdwt is a cross-platform discrete wavelettransform library implemented in C language. The library implements fast wavelettransform algorithm using lifting scheme. Cohen-Daubechies-Feauveau wavelets with 4 vanishing moments were used.
A library written in C for lossy image compression. Library libopen/format OPEN supports two methods of compression - discrete cosine transform (used in JPEG) and discrete wavelettransform (used in JPEG2000).
