Minutiae-based representation is the most widely adopted fingerprint representation scheme. The compactness of minutiae template has created an impression that the minutiae template does not contain sufficient information to allow the reconstruction of the original fingerprint image. This belief has now been shown to be false; several algorithms have been proposed that can reconstruct fingerpri...

RF/microwave MEMS technology. Part one begins with a brief discussion of RF/microwave system requirements, and then introduces the enabling potentialities of the MEMS arsenal to meet these requirements. In particular, MEMS fabrication techniques are addressed, and fundamental components, including inductors, varactors, resonators and transmission lines, as well as the design/ CAD paradigm, are ...

In this paper we study that fingerprints are the oldest and most widely used form of biometric identification. The widespread use of fingerprints, there is little statistical theory on uniqueness of fingerprint minutiae. A critical step in study statistics of fingerprint minutiae is to reliably extract minutiae from the fingerprint images. Automatic and reliable extraction of minutiae from the ...

MEMS components by their very nature have different and unique failure mechanisms than their macroscopic counterparts. This paper discusses failure mechanisms observed in various MEMS components and technologies. MEMS devices fabricated using bulk and surface micromachining process technologies are emphasized.

Fingerprint identification and verification are one of the most significant and reliable identification methods. It is impossible that two people have the same fingerprint. Automatics identification of humans based on fingerprint requires the input fingerprint to be match with a large number of fingerprints in the database. Generally, the fingerprint recognition systems are unable to solve the ...

The performance of an automatic fingerprint verification approach relies heavily on the quality of the fingerprint image. Enhancement of the fingerprint image is then a crucial step in automatic fingerprint verification. This paper discusses the fingerprint image processing methods for automatic verification and proposes an adaptive oriented low pass filter to enhance the fingerprint image qual...

The microelectromechanical systems (MEMS) area has been developed extensively during the past three decades. In the 1970s, with the advancement of semiconductor microelectronics processing, researchers investigated wet anisotropic chemical etching processes for forming three dimensional silicon geometries. In the 1980s, researchers adopted the Metal-Oxide-Semiconductor (MOS) process to realize ...
