The study of the second generation of wavelet transform

Recently, the second generation wavelet which is lifting scheme of the first generation wavelet has attached much attention, because it keeps the good characteristics of the first generation wavelet transform and gets over the limitation of the first generate wavelet transform. This paper expounds of the lifting scheme and the excellent characteristics of the second generation wavelet transform, and makes comparison between the first generation wavelet ransform(DWT) and the second generation wavelet transform(LWT).
