a= bitget(cover_image(ii,jj),1)
watermarked_image = bitset(cover_image(ii,jj),1,share1(ii,jj)
when i run it .... i get value of lsb one after another, but assign last result as permanent value of a .... i need to save all the values... so then can be placed back
a(ii,jj) = bitget(cover_image(ii,jj),1) is neither helping...... cover image is an blue panel of RGB image.... i m new to matlab ..... plz plz plz help.... i m stuck badly ...... thnks in advance
