Digital image processing: Paper presentation

•Unlike Fourier transform, whose basis functions are sinusoids, wavelet transforms are based on small waves, called wavelets, of limited duration.
•Fourier transform provides only frequency information, but wavelet transform provides time-frequency information.
•Wavelets lead to a multiresolution analysis of signals.
•Multiresolution analysis: representation of a signal (e.g., an images) in more than one resolution/scale.
•Features that might go undetected at one resolution may be easy to spot in another.
