So when you use a “Wavelet Transform,” the image deconstructs using the same wavelet function at different scales, rather than the same sine wave at different frequencies.

The transform is similar to applying Fourier, but instead of decomposing to a series of infinite sine waves, wavelet transformation decomposes signals into finite functions that meet certain ...

We attempt to recover an unknown function from noisy, sampled data. Using orthonormal bases of compactly supported wavelets, we develop a nonlinear method which works in the wavelet domain by simple ...
