Wavelet Transforms That Map Integers to Integers
TL;DR: Two approaches to build integer to integer wavelet transforms are presented and the precoder of Laroiaet al., used in information transmission, is adapted and combined with expansion factors for the high and low pass band in subband filtering.
Proceedings ArticleDOI
Lossless image compression using integer to integer wavelet transforms
TL;DR: This work presents an approach to build integer to integer wavelet transforms based upon the idea of factoring wavelet transformations into lifting steps, which allows the construction of an integer version of every wavelet transform.
