Sir,
i am a new user of Matlab for my graduate project . Please help me for dividing an image of 256*256 in to the 8*8 blocks . Each block can be accessed later for further processing (dct,ac dc values of block and few more). My my project is on Content based image watermarking using fuzzy logic.Thanks in advance

Thanks & Regards
Aashish Joshi
