Attack of Mechanical Replicas: Liveness Detection With Eye Movements

Posted on January 28, 2016 by Matlab-Projects |

This paper investigates liveness detection techniques in the area of eye movement biometrics. We investigate a specific scenario, in which an impostor constructs an artificial replica of the human eye.…

Estimation of gaze for human computer interaction

Posted on January 28, 2016 by Matlab-Projects |

Gaze of the human eye may act as a communication medium for limb disabled people to interact with computers. In order to determine gaze direction, the first necessary step in…

An Investigation of Local Descriptors for Biometric Spoofing Detection

Posted on January 28, 2016 by Matlab-Projects |

Biometric authentication systems are quite vulnerable to sophisticated spoofing attacks. To keep a good level of security, reliable spoofing detection tools are necessary, preferably implemented as software modules. The research…

Design and development of a rope climbing robot using four bar mechanism with wireless control using TX2/RX2 RF module

Posted on January 28, 2016 by Matlab-Projects |

This paper describes the design and development of a rope climbing robot using four bar mechanism, which enables the robot to climb over an inclined ropeway. In this research, our…

Empirical equation for carrier power dependence of passive intermodulation product

Posted on January 28, 2016 by Matlab-Projects |

This paper proposes an empirical equation for input carrier power level dependence of 3rd order reflected passive intermodulation (PIM) product. Three kinds of microwave passive devices, namely, directional coupler, N…

Robust widely linear beamformer based on a projection constraint

Posted on January 28, 2016 by Matlab-Projects |

For noncircular signals, optimal widely linear (WL) minimum variance distortionless response (MVDR) beamformer has a powerful performance by exploiting the noncircularity of the received signals. Though, the noncircularity rate can be estimated…

Applications of narrow-filtering based on optical coherent detection

Posted on January 28, 2016 by Matlab-Projects |

Processing of high-frequency, wide-band signals is conveniently performed in the optical domain due to availability of optical filters which intrinsically have a wide-band response. On the other end, there are several application scenarios…

Robust Ellipse Fitting via Half-Quadratic and Semidefinite Relaxation Optimization

Posted on January 28, 2016 by Matlab-Projects |

Ellipse fitting is widely applied in the fields of computer vision and automatic manufacture. However, the introduced edge point errors (especially outliers) from image edge detection will cause severe performance…

Revocable key generation from irrevocable biometric data for symmetric cryptography

Posted on January 28, 2016 by Matlab-Projects |

Crypto-biometric system (CBS) is a combination of biometrie with cryptography to enhance network security. Biometrie is the most trustworthy measure to identify a person uniquely using his or her behavioral…

Wideband DTV passive ISAR system design

Posted on January 28, 2016 by Matlab-Projects |

Advanced operational modes for passive radar, including inverse synthetic aperture radar (ISAR), require particular consideration with respect to the receiver hardware. The spatial and spectral diversity of passive illuminators necessitates…
