Iris authentication in handheld devices – considerations for constraint-free acquisition

Posted on January 28, 2016 by Matlab-Projects |

As a near ideal biometric, iris authentication is widely used and mobile acquisition techniques are known. But iris acquisition on handheld imaging devices, such as smartphones, poses multiple, unique challenges. In this paper, a…

A fast iris localization using inversion transform and restricted circular Hough transform

Posted on January 28, 2016 by Matlab-Projects |

This paper presents a fast segmentation of iris portion from an eye image in an iris recognition system. In iris segmentation, we have to find the inner boundary (between pupil and iris) and outer boundary (between sclera and iris).…

Characterizing opportunistic communication with churn for crowd-counting

Posted on January 28, 2016 by Matlab-Projects |

In opportunistic networking, characterizing contact patterns between mobile users is essential for assessing feasibility and performance of opportunistic applications. There has been significant efforts in deriving this characterization, based on…

A band-reject frequency selective surface with stable response for WLAN applications

Posted on January 28, 2016 by Matlab-Projects |

In this paper, a new design of band-reject frequency selective surfaces is proposed. Compared to previous compact structure, the FSS proposed has a better firm performance with the dimension of…

New pre-emptive arc fault detection techniques in medium voltage switchgear and motor controls

Posted on January 28, 2016 by Matlab-Projects |

For Forest Products based industries, the significant benefits of pre-emptive arc-flash protection and online condition monitoring of electrical equipment are not well known. This paper provides a summary the research…

Simple Broadband Quasi-Optical Spatial Multiplexer in Substrate Integrated Technology

Posted on January 28, 2016 by Matlab-Projects |

We present a new type of broadband spectral-spatial quasi-optical decomposer for microwave analogsignal processing fully implemented in substrate integrated waveguide (SIW) technology. An input SIW is modulated to couple energy to a…

A drowsiness detection method using distance and gradient vectors

Posted on January 28, 2016 by Matlab-Projects |

This paper presents a drowsiness detection for drivers. The drowsiness is detected by monitoring the eye state (open or close). Firstly, human face detection is performed using the Haar cascade…

An algorithm to differentiate astigmatism from Keratoconus in Axial Topgraphic images

Posted on January 28, 2016 by Matlab-Projects |

Keratoconus is a vision disorder that occurs when the normally round cornea becomes thin and irregular shaped. This abnormal shape prevents the light entering the eye from being focused correctly…

Detection of bifurcation angles in a retinal fundus image

Posted on January 28, 2016 by Matlab-Projects |

Security issues related to fake passports etc., used in various situations like air travel etc., protecting the identity of a person is an essential task. To prevent someone’s identity from…

Highly linear continuous-time MASH ΔΣ ADC with dual VCO-based quantizers

Posted on January 28, 2016 by Matlab-Projects |

This paper proposes a new continuous-time (CT) MASH delta sigma (ΔΣ) modulator topology in which dual VCO-based quantizers are incorporated. The nonlinearity of both voltage-controlled oscillators (VCOs) caused by their…
