Wavelet transform functions implement Mallat's algorithm (an iterate algorithm in the Discrete Wavelet Transform field) and apply wavelet transform on multiple sequences simultaneously, or perform the inverse of this process.

  • DWT implements Mallat's algorithm and applies wavelet transform on multiple sequences simultaneously.
  • DWT2D is DWT for 2-dimensional matrices.
  • IDWT is the inverse of DWT.
  • IDWT2D is the inverse of DWT2D.
