RE: [WM]: Query on Digital Watermarking

Dear K. Bhanu Prasad,

Could you tell me how to "blindly convert the MATLAB code to C code"? Thank you!

John




Hi Vijay,

       First of all test and implement the algorithm on MATLAB. Verify it and test it on MATLAB. Then you can blindly convert the
code to C.
You can directly code in C but it is not advisable.


Download corresponding Papers from IEEE and you have to slog it out.
Bottom line is that one must learn MATLAB, implement on it. There Is no other way out for these complex algorithms.


Best of luck

With Regards,
K. Bhanu Prasad

Subject: [WM]: Query on Digital Watermarking

Dear watermarkers
  
  I am final year student of software engineering and i am doing a project on Invisible Watermarking of Digital Images for Copyright
Protection but i do not have pre knowledge of this field but till now i have done lot of research work on it and have gone through
Digital Image  Processing books. Now i am familiar with image like what is a image and how to operate on them.
  
    i wrote few programs like histogram equalization, median filter, negative etc. using VC++ and Vision SDK tookit.
  
  But i have few problems  as stated below-
  
  1) As image processing is totaly mathematical so i am finding difficulties in converting large mathematical equation into
programs. can any body tell me easiest way to do it.
  
  2) i am not getting any idea on how to implement watermark on image 
  
  3) i will be using Haar Wavelet Transformation algorithm. But the concept of Wavelet and Multiresolution band, Subband is not
clear to me.
  
  4) What is a band in an image context. how can i understand it.
  
  Can you guys help me out with some useful solution.
ALso plz tell me any site where i can get some sample programs in image manipulation using VC++ platform.
  
  Plz Guide me in my project...................
  
  
  Thanking You
  
  
   
  



Best Wishes!!
Vijayendra Gaur
