| In recent years, new forms and techniques of
teaching have appeared, based on the Internet and on multimedia
applications. In the teleteaching Project Virtual University of
the Upper Rhine Valley (VIROR), multimedia simulations and
animations complement traditional teaching material. Lecturers
use Java applets in their courses to explain complex structures.
These are then stored in a multimedia database to enable
asynchronous learning. The wavelet transform has become the most
interesting new algorithm for still image compression. Yet, there
are many parameters within a wavelet analysis and synthesis:
choice of the wavelet filter bank, decomposition strategy, image
boundary policy, quantization threshold, etc. We consider the
wavelet transform to be a typical example of a complex,
hard-to-understand algorithm that needs illustration by
interactive multimedia. In this article, we present the didactic
background and the implementation of a sample applet on the
discrete wavelet transform, as taught in our multimedia
course. |
