A Symbolic Representation of Waveforms Using Multi-Resolution Analysis
Dr. Aviad Zlotnick
Department of Mathematics and Computer Science
Hebrew University, Israel
A multi-resolution technique for ``qualitative'' analysis of waveforms was
suggested by Witkin in 1983, and has since been studied extensively, both
in theory and in practice. In the first part of the talk we reconsider
Witkin's definition of qualitativity and outline a few weaknesses of his
method. In the second part we describe a representation based on an
alternative definition of qualitativity. We show that our method results
in waveform descriptions which are nearer to human intuition, are easier
to compute and can incorporate more domain knowledge. Furthermore, a
symbolic (verbal) description of waveforms derived from this representation
is shown to capture the waveforms' essential visual properties.
