Module 10.5: Compression of Clown Image Using Daubechies Wavelets

This module computes the D3 Daubechies wavelet transform of the clown image, sets to zero values below a threshold, and reconstructs the clown image from its thresholded wavelet transform. The threshold is set by a slider, and the resulting compression ratio (number of pixels divided by number of nonzero wavelet coefficients) is computed. This module is an interactive version of Fig. 10-30.
