digital watermarking matlab

Well , i need to seach 4 the codes from my cds now. Its been 3 years back that i worked with it and never opened it again .

A brief intro about it i can give u and can support u in ur code wrk too.

Try working with matlab that helps u better.

I worked with .wav file as sample to achieve Digital Audio watermarking. U can use audicity to get the wav files from mp3 if am nt wrong (i think ..audocity exports wavfiles from mp3).

The technology I used was discrete wavelet transform using db6 filter.

The robi polikar notes on wavelets are excellent one to be refd.

The IEEE site gives you enough info on watermarking , say the IEEE Signal processing july2001 issue speaks a lot about digital watermarking.


If any of my mesgs was found worthy by you will be glad

Regards,

Ashwini

audocity and watermarked mp3

hey am very sorry its audacity.. i misspelled it b4.

http://audacity.sourceforge.net/

The paper can be got from

http://ieeexplore.ieee.org/xpl/freeabs_all.jsp?tp=&arnumber=939835&isnumber=20339


let me know if u find it useful and please tell me what is your plan of work.

Getting you the code might take some time. meanwhile if you try it out using matlab that will be fine. what do you do?? what sort of audio signal are you processing with? what is the aim of your project?

i should have asked these before. no pbm..reply back when you have time

Regards,
Ashwini

rapidshare wavelet watermarking

yeah... i mean... verymuch like a real time.

U run the Encoding module of watermark code ..take input from mic and start watermarking your speeh signal . save the coded file on ur PC.


Hear it using media player
( watermark signal shouldnt be heard from the audio file )

Then run the decoding module and see the graphical rep of the decoded signal. Save the decoded audio file or the wav file on ur PC.

hear it using media player

when u do it all ur self , its a miracle i say

Now isnt it a real time project

steganography ieee rapidshare

Hey leo ,

I need this week end to find the code for you. I have it safely locked in my cupboards.

Then tell me how can i help u meanwhile. any sort of clarification that you need is welcomed.

Start working with auread and auwrite that should be fine.

actually the concept alone is really big. the code will be just 15-20 lines ..

u neednt worry at all it would work really fine


its all a piece of cake once u r strong with concepts

mail me abt wht u have done till now.

did u go thru the paper i sent u?

r u comfortable now with DWM
