Description: To recover the original image losslessly, reversible wavelet transform should be used. Hence we employ the
integer wavelet transformation which maps integer to integer and can reconstruct the original signal without
any distortion. Although various wavelet families can be applied to our reversible embedding scheme, through
experimental comparison we have discovered that CDF(2,2) is better than other wavelet families in terms of
embedding capacity and visual quality of embedded images. In addition, it is noted that CDF(2,2) format h as
also been adopted by JPEG2000 standar
