Wavelet Toolbox

Analyzing Signals and Images

The Wavelet Design and Analysis app enables you to perform wavelet analysis, wavelet packet analysis, denoising, and compression on 1D and 2D signals. For 1D signals, you can:

  • Perform discrete wavelet analysis of signals
  • Perform continuous wavelet analysis of real signals using complex wavelets
  • Denoise signals
  • Estimate wavelet-based density
  • Perform wavelet reconstruction schemes based on various wavelet coefficient selection strategies
  • Randomly generate fractional Brownian motion
  • Perform 1D signal extension and truncation using periodic, symmetric, smooth, and zeropadding methods
  • Perform 1D signal clustering and classification using wavelet analyses (with Statistics Toolbox, available separately)

For 2D signals, you can:

  • Perform discrete wavelet analysis of images
  • Fuse two images
  • Perform translation-invariant denoising of images, using the stationary wavelet transform
  • Reconstruct wavelet schemes based on various wavelet coefficient selection strategies
