A wavelet-lifting scheme that maps integers to integers, performs all calculations in-place, and is computationally efficient is used in this paper. It processes 2-D medical images row by row producing an equivalent 1-D signal. The interdependency of pixels in 2-D medical images is known to vary in different regions. Thus, some lifting schemes decorrelate the resultant signal more efficiently than others do. The effect of different scanning approaches on the performance of several lifting schemes is presented.
