Title: An approach of integer reversible wavelet transform
for Image Compression

Abstract. In this paper, we are going to propose a general method for
creating the integer wavelet transforms which can be used in both
lossless (reversible) and lossy compression of signals and images with
arbitrary size. This method allows us to get a series of transformations
which are very close to the corresponding biorthogonal wavelet
transforms or some non-orthogonal wavelet transforms, but can be
calculated with only integer addition and bit-shift operations. In
addition, the integer wavelet transforms created in this paper possess a
property of precision preservation (PPP). This property is very useful
for saving memory in both compression and decompression, and speed up
the whole procedure in some applications. The motivation of this paper
comes from lifting scheme and S+P transform.
