matlab - Image steganography based on DWT integer coefficients -


i trying code dwt based steganography hide image inside image. getting coefficients of subbands float. how can make them integers can use lsb embedding?

this known integer wavelet transform. in matlab achieved using lifting schemes. define lifting scheme liftwave , use lwt2 , ilwt2 transformations.

lshaar = liftwave('haar','int2int');  [ca ch cv cd] = lwt2(x,lshaar);            % x data ilwt2(ca,ch,cv,cd,lshaar);
