Summary: (Blank Abstract)

The Haar basis is perhaps the simplest example of a DWT basis,
and we will frequently refer to it in our DWT development.
Keep in mind, however, that *the Haar basis is only
an example*; there are many other ways of
constructing a DWT decomposition.

For the Haar case, the mother scaling function is defined by Equation 1 and Figure 1.

From the mother scaling function, we define a family of
shifted and stretched scaling functions

which are illustrated in Figure 3 for
various
