Re: [WM]: bior4.4 matlab function

Hi Mostafa,

Well, since I worked on bior1.1, and some other biorthogon= al splines wavelets, I can tell that you can understand
your resulting matr= ix better if u tried all the bior splines before 4.4, i mean: notice the ma= trices that will result if you
apply bior1.1, 1.3, 1.5, and 1.7 respectivel= y.

Hope you benefit from this
Suhad.

Subject: [WM]: bior4.4 matlab function


hi watermarker

                     I tried to decompose 512 * 512 grayscale image using
bior4.4 matlab fun= ction by using wavedec2 function  but always get output
of the correspondin= g bookkeeping matrix S as

>>[w s]=wavedec2(double(I),4,'bior4.4');
>>s =

          40    40
          40    40
          71    71
          134   134
          260   260
          512   512

But I expected  it to be in the form

  32    32
  32    32
  64    64
  128  128
  256  256
  512  512

I would be thankfull if any o= ne tell me why the corresponding bookkeeping matrix S
is equal the values i=  mentiones not the value i
expected

Mostafa
