I have project "A Robust Digital Watermarking with Mixed Transform Technique for Digital Image".
There are two attachtment, the sourecode I made, and the embedding and extraction watermark process.
I've done the DWT process, and have problem with dividing into blocks of 8x8 pixels. Can you help me?

>> A=rand(24); mat2tiles(A,[8,8])
ans =
[8x8 double] [8x8 double] [8x8 double]
[8x8 double] [8x8 double] [8x8 double]
[8x8 double] [8x8 double] [8x8 double]

The function blockproc in the Image Processing Toolbox maybe a natural fit if you would like to do process the image in blocks.
