matching pursuit source code java

Hi, dear friends, do you know where I can find some source code on wavelet applications? I think it's a better way to read the source code to study wavelet. Do you think so?
 

Hi saryee,

If you need source code I would advice you to check Matlab Wavelet Toolbox. The code is open.

IMO however it is better to start from a good book. Look for the 'wavelet' in edaboard.com and will find lot of resources.

For gentle introduction can check **broken link removed**
also.

If you are more math guy check 'A First Course on Wavelets' by the CRC press.

newly published jpeg2000 standard uses DWT in transform domain.
you can read the sourcecode of its implementation for refercence.
There are opensource implementations of j2k, for example jasper or jj2000.
if you are familiar with java, you can read jj2000. If prefer to C, read jasper.
 

if you design some simulation program, you can use matlab which contain a lot of ready made function available.
 

here is a site that offer a very good matlab wavelets suits (free):

https://www-stat.stanford.edu/~wavelab/

here are some details:
WaveLab is a collection of Matlab functions that have been used by the authors and collaborators to implement a variety of computational algorithms related to wavelet analysis. A partial list of the techniques made available:

orthogonal wavelet transforms,
biorthogonal wavelet transforms,
translation-invariant wavelets,
interpolating wavelet transforms,
cosine packets,
wavelet packets,
matching pursuit,


and more....
 

Did anyone can recommend any applicaiton notes on the wavelet application in power systems?

Thanks a lot!
 

Dear Friend:

I had the same problem as you have. I suggest to you first overall understand where wavelets come from. Check "wavelets for kids", " A primer on wavelets an thier scientific applications". You can download these books here.

You can understand with these texts how wavelets works. Why understand wavelets? 'cos If you need to change some parameters like resolution or scale at simulations or better if you need to apply this in a FPGA or DSP a good theorical reference could avoid you undesired results or an inefficient implementation on these devices, overall if you need to change paremeters and have another characteristics than dyadic equations.

Regards!
 

thank you ,i have the same problem as you have.
