[WM]: bior4.4 matlab function

["Mostafa mohsen" <orange1704@hotmail.com>]

hi watermarker

                     I tried to decompose 512 * 512 grayscale image using
bior4.4 matlab function by using wavedec2 function  but always get output of the corresponding 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 one tell me why the corresponding bookkeeping matrix S is equal the values i mentiones not the value i
expected
