Domain-specific

• Discrete wavelet transform
  • A one-level critically sampled DWT maps a sequence (x[k]) to approximation coefficients \(a_1[n]=\sum_k h[k-2n]x[k]\) and detail coefficients \(d_1[n]=\sum_k g[k-2n]x[k]\), with further levels recursively decomposing the approximation branch under the selected convention.
• Multiresolution Analysis
  • Mallat's formulation showed how this nested approximation structure yields orthogonal wavelets and a pyramidal filter-bank algorithm.
