| Summary: | 碩士 === 國立中山大學 === 電機工程學系研究所 === 98 === With an increasing emphasis on personal privacy, security, and convenience, the
security of identification system is an important issue nowadays. In this thesis, two
intelligent identification systems, laser speckle image identification system and
laser-based finger biometric system, are proposed to perform superior solutions for
identification applications. In laser speckle image identification system, we
investigated the characteristics of laser speckle as well as proposed an appropriate
algorithm to establish this system. The proposed algorithm is a coarse-to-fine process
which identifies laser speckle images systematically. In laser-based finger biometric
system, a new biometric approach is described to proceed personal identification
using a scanner with a low power laser scans across the surface of the finger and
continuously recording the reflected intensity at a fixed position. Experimental results
show that the recognition rates of the proposed system are both 100%.
