<div class="textblock"><p>Implementation of a discrete wavelet transform (DWT) </p>
<p>The functions in DWT.C have for goal to realize forward and inverse discret wavelet transform with filter 5-3 (reversible) and filter 9-7 (irreversible). The functions in DWT.C are used by some function in TCD.C. </p>
