**Daubechies wavelet**Hi everybody,
I'm trying to reproduce daubechies basic building graph and daubechies wavelet function graph (φ(r)=0 if r≦0 or 3≦r). And i found this algorithm. I would appreciate if there is anybody could help me to understand the function defined below as function [s,w] = cascade(n,cs,cw). Especially how does the convolution takes place. Thank you in advance.

**I need matlab code for WAvelet Image Compression**hello
i'm in need of matlab code for wavelet based image compression using
SPIHT, EBCOT and EZW algorithms. please mail me the details of the
source code or the website where I can download it.
Thanks in advance,
Marco L.
Marco,
I cannot vouch for the validity of the code, but I found an implementation
of the EZW algorithm here:
http://perso.wanadoo.fr/polyvalens/clemens/ezw/ezw.html
A quick google search on "SPIHT MATLAB" turned up some options to track
down, but I didn't have time to look further. Good luck!
Thanks,

**matlab code image compression using wavelet**hi.
i am working in image compression using matlab but i am not getting
the proper code for that..
please any one can help me..
..
thank you.
Hi,
It is nice doing a project on Image Compression.
There are different techniques for that.
I will suggest you the following methods.
1, Implementing the Multi Resolution Filters
2. using SPIHT algorithm ( Set Partioning in Hirarcheal tress)
3. Implementing EZW ( Embedded Zero Wavelet).
The following URL you can use for the code and for the details.

**MATLAB CWT function**Hi, I am using the MATLAB wavelet toolbox function CWT with the
complex Morlet wavelet. I would like to do a cwt with a Morlet
wavelet size ranging from 512 ms (at highest scale) to 32 ms (at
lowest scale). As my signals are sampled at 16 kHz the 512 ms would
equal 8192 samples and the 32 ms equal 512 samples. I think I have to
adjust the Fb parameter as it controls the bandwidth and hence also
the size of the Morlet wavelet in the time domain.
(I set the Fc parameter to 0.875)
Does anybody know how to specify the size of the Morlet wavelet ?
Thanks,
Marco

**matlab function for wavelet integer to integer transform**Hello, all:
Thank you in advance for the help. I have to admit that I am almost
ignorant on wavelet although I sometime use the matlab wavelet toolbox
for de-noising. I need to do some lossless compression using wavelet.
I found the reference [1]. But it is beyond my domain to implement it.
I am I am wondering if the integer to integer transform using wavelet
has been implement as a function in matlab. The function probably
should look something like
transformed_integer_series = wavelet_int2int(original_integer_series,
wavelet_chosen)
Thank you very much...

You couldnt find it in wavelet toolbox?
See

If you dont have wavelet toolbox, you may download it from statistics
department of Stanford university. You could also find the link from
Donoho's webpage.
Hope that it would be helpful.

Dear Prasad:
What did you learn about "Image compression using Wavelet transform
in MATLAB" during the semester? I could be wrong, but I would assume
that this project was assigned in part to measure what you were
expected to learn during your studies. If that is true, why are you
asking someone else to do your work for you? When you graduate and
