Detailed Description and Outline


  1. Introduction and background: why wavelets, filter banks, and multiresolution analysis? signal spaces and operators; review of Fourier theory; multirate signal processing; time-frequency analysis.
  2. Discrete-time bases and filter banks: series expansions of discrete-time signals; analysis and design of filter banks; orthogonal and biorthogonal filter banks; tree-structured filter banks; discrete wavelet transform.
  3. Continuous-time bases and wavelets: multiresolution analysis; iterated filter banks; wavelets and filter banks; wavelet series and its properties; regularity and approximation properties.
  4. Overcomplete expansions and continuous transforms: frame theory; oversampled filter banks; continuous wavelet and short-time Fourier transforms.
  5. Advanced topics: sparse representation; linear and nonlinear approximation in various bases; nonlinear signal estimation; multidimensional filter banks and wavelets; multiscale geometric image processing; compressed sensing.
  6. Applications: speech, audio, image and video compression; denoising; feature extraction; inverse problems.
