Masahiro Iwahashi, Yoshihide Tonomura, Somchart Chokchaitam, Noriyoshi Kambayashi · Electronics Letters · 2003
Quantisation prior to the integer wavelet transform (Pre-Qnt) is introduced. The best combination of the Pre-Qnt and the conventional post-quantisation (Post-Qnt) in multi-stage band splitting based on the integer wavelet transform is presented.
