Lifting scheme and image coding: average interpolating image coding
Zeng Jianfen, Zhengming Ma · 2002
A lifting scheme, from new wavelet research, can be used to implement the existing wavelets and to construct completely new wavelets. We construct the average interpolating wavelet of 2 degree and apply it to image coding; finally, we get an image coding result as good as, if not better than, that of the D9/7 recommended by JPEG2000 draft. The lifting step of the average interpolating wavelet is much simpler than that of the commonly used D9/7, which means the computational resources consumed here is much less.
