The Wolfram Demonstrations Project contains thousands of free interactive visualizations, with new entries added daily.

Three iterations of the discrete wavelet transform are computed using the Daubechies six-term filter. The wavelet transform splits the data into lowpass (approximation) portions and highpass (detail) portions. Wavelet shrinkage reduces the magnitude of ...
