Abstract :
The multi resolution nature and energy compaction of wavelet transform particularly makes them suitable for analysis of biological features both behavioral and physiological. The paper proposes to use Daubechies 3 and 4 wavelets to analyze the iris pattern and speech samples with the application of decision theory in case the stand alone systems of speech identification and iris recognition yield conflicting results.
