For the image enhancement process, we use something called a stationary wavelet transform. Basically, this is a special case of the wavelet transform where the image is not decimated between levels in the filter bank. With suitable scaling steps (e.g., doubling s for each wavelet), the wavelet basis acts like a bandpass filter bank, each expanded wavelet providing a lower (and compressed) frequency band. A time-frequency scrambling algorithm based on wavelet packets was proposed by Ajit S. His talk titled Wavelet Filterbanks on Graphs: A New Tool for Multiresolution Analysis of Graph Data will describe his work on leveraging novel basic wavelet techniques for analyzing data on graphs. Signal Analysis explores methods that offer an insight into the properties of signals and stochastic processes. Signal analysis: wavelets, filter banks, time-frequency transforms and applications.

In summary, we can construct overcomplete discrete WTs based on rational dilation factors that are efficiently implemented with FIR digital filter banks, easily invertible, designed according to vanishing-moment and regularity conditions, and approximately shift invariant.

Short filters with vanishing-moment properties, useful for the construction of self-inverting rational wavelet frames, can be constructed by solving a polynomial-matrix spectral factorization11 problem.
