Software: Wavelet Toolbox for Khoros2.0

Uvi_Wave Pre-release

WAVELET TOOLBOX for KHOROS2.0

A Pre-release of the Uvi_Wave Wavelets toolbox for Khoros 2.0 is
available via anonymous ftp from:

ftp.tsc.uvigo.es:/pub/Uvi_Wave/khoros2/

or

ftp.cesga.es:/pub/Uvi_Wave/khoros2/

This new software is still being developed. Comments, suggestions and
bug reports will be greatly appreciated. The mail address for reports is
Uvi_Wave@tsc.uvigo.es

The programs included in the toolbox are :
(A more extensive repport will be included in the ftp server)


MAIN PROGRAMS:

* KMWT: The Multilevel Wavelet Transform. Supports the multiscale
(different
number of scales for each direction) feature and fast matricial
computations have been included.
kmwt supports the following tasks:
- The multilevel Direct and Inverse Wavelet
Transform. With variable
number of scales for each dimension, as
extended options.
- Incomplete Inverse transform for multirresolution
analysis purposes.

* kwtband : It's a program which supports up to 8 subband
utilities: extraction,
insertion, normalization, location, ....
kwtband supports the following tasks:
- Subband Normalization for viewing.
- Subband Extraction-Insertion routines (different options for
insertion).
- Subband Location Change.
- Subband Localization.

* kwwavscl : The program that calculates the Wavelet and Scale functions.
kwwavscl supports the following tasks:
- Wavelet Function generation.
- Scale Function generation.

* kwtfilter : The Filter Generator.
kwtfilter supports the following tasks:
- Generation of Daubechies Orthogonal filters.
- Generation of Spline Biorthogonal filters.

* kwmres : The Multiresolution Analysis module. Computes approximations and
details from objects.
kwmres supports the following tasks:
- Calculation of any approximation or detail of any
object, where the band selection is made independently
by directions.

OTHER FILES:

* Other pane programs: The above programs have been provided with several
pane files with different levels of complexity according to the
user's needs.


* Library routines: The toolbox library holds a bunch of little aid
routines for coordinate and size calculation, scale checking,
and others.


We hope this will help about the toolbox structure. You may try the
Matlab version of the toolbox, available at the same site.
