Biorthogonal Wavelets
- Bath Wavelets ('Bathlets')
- These wavelets have been designed based on a balanced weighted uncertainty approach. Information on the design method involved can be found in [1]. A zip file is available here that contains all of the biorthogonal wavelets generated from the research in [1].
- Biorthogonal Haar type wavelets
- A zip file is available here that contains biorthogonal Haar wavelets.
- UCLA Evaluated Wavelets
- A zip file is available here that contains all of the wavelets evaluated in [2].
- Fingerprint Wavelets
- This filter, fbi.wvf, is used by the FBI for fingerprint compression as described in [3].
- Other Wavelets
- Biorthogonal modified Coiflet filters [4] (modbicoif1711.wvf).
- The lazy wavelet (lazy.wvf).
- The 5/3 wavelet (5_3.wvf).
- The 7/5 wavelet (7_5.wvf).
Orthonormal Wavelets
- Bath Wavelets ('Bathlets')
- These wavelets have been designed based on a balanced weighted uncertainty approach [5]. A zip file is available here that contains Orthonormal wavelets with balanced uncertainty of various lengths.
- Complex Bathlets
- The Haar wavelet
- Daubechie's Maximum Flat (Maximum regularity) Wavelets
- The zip file here, contains Daubechies wavelet filters of various lengths.
- Coiflets [6]
- The zip file here, contains Coiflet wavelet filters of various lengths.
- Daubechies Maximum Symmetry Wavelets - 'Symlets' [7]
- The zip file here, contains Daubechies Maximum Symmetry wavelet filters of various lengths.
Other Wavelets
- A wavelet designed to reduce coding artifiacts [8].
- The wavelet file (here), contains this wavelet. Please visit Wavelet Digest where you can find more information out about this wavelet.
