Details for Javascript program for Daubechies
wavelet transform computation and image denoising

This program adds noise to the image selected from the dropdown menu,
computes the 2-D Daubechies db3 wavelet transform of the noisy image,
thresholds and shrinks (soft thresholds) the resulting wavelet transform,
and inverse wavelet transforms the result (see Chapter 7). Setting
σ=0 and λ=0 displays the wavelet transform of the selected image.

Slides: σ=noise strength, λ=threshold.
Displayed: Original image, noisy image, its wavelet transform, denoised image.
