Invertible wavelet transforms that map integers to integers are important for lossless
representations. We present an approach to build integer to integer wavelet transforms
based upon the idea of factoring wavelet transforms into lifting steps. This allows the
construction of an integer version of every wavelet transform. We demonstrate the use of
these transforms in lossless image compression.
