Introduction to The Lifting Scheme

Introduction to The Lifting Scheme . Wavelet Transforms. Two approaches to make a wavelet transform: Scaling function and wavelets (dilation equation and wavelet equation) Filter banks (low-pass filter and high-pass filter) The two approaches produce same results, proved by Doubeches.
