The paper proposes new spatial lifting scheme for images. Compared with recently proposed non-separable structure, the proposed scheme reduces the number of operations.
We have reduced the number of lifting steps in the calculation of the two-dimensional discrete wavelet transform by factoring the underlying lifting scheme into a new spatial form. Compared with recently proposed non-separable structure, we have reduced also the number of operations. Our scheme is primarily designed for CDF 5/3 and CDF 9/7 wavelets employed in JPEG 2000 image compression standard. In the result, our scheme requires only two steps for 2-D CDF 5/3 transform compared to four steps in the original separable form or three steps in the recent non-separable scheme.
