INTRODUCTION
MULTIBIOMETRIC – multiple biometric sources for
human recognition.
Searching a biometric database for an identity.
Retrieval of identities from database by database filtering.
• Classification scheme
• Indexing scheme
It employ cascading technique for filtration process.

COMPUTATION TIME
tm -computation time for a single match operation
tc -computation time for a single correlation coefficient
n -number of reference images
Speedup is achieved when the following inequality holds:
