In this paper, Clemens Valens presents the wavelet transform and develops a scheme that will allow you to implement the wavelet transform in an efficient way on a digital computer. The transform will be so efficient that it does not even use wavelets anymore. Since wavelet theory is not a new thing anymore, it has been around now for fifteen years, say, this article does not present a full and in-depth theory. Several good textbooks on wavelet theory are available and many readable papers with a good review of wavelet theory have been published. The article does, however, present some mathematical background in order to tell a coherent and clear tale.
