Video Presentation Attack Detection in Visible Spectrum Iris Recognition Using Magnified Phase Information

Posted on January 30, 2016 by Matlab-Projects |

The gaining popularity of the visible spectrum iris recognition has sparked the interest in adopting it for various access control applications. Along with the popularity of visible spectrum iris recognition comes the threat of identity spoofing,…

Predicting segmentation errors in an iris recognition system

Posted on January 30, 2016 by Matlab-Projects |

Iris segmentation is defined as the isolation of the iris pattern in an eye image. A highly accurate segmented iris plays a key role in the overall performance of an iris recognition system, as shown in previous research.…

Fast realistic refocusing for sparse light fields

Posted on January 30, 2016 by Matlab-Projects |

Digital refocusing for sparsely sampled light fields results in aliasing effect. For realistic quality, previous works performed anti-aliasing by applying time-consuming view interpolation for a heuristic number of novel views. In…

A Reflector Antenna Concept Robust Against Feed Failures for Satellite Communications

Posted on January 30, 2016 by Matlab-Projects |

Since the first communications satellites have been launched to space with the beginning of the 1960s, these systems have undergone a rapid development. Amongst others, this development is driven by…

A light field sparse representation structure and its fast coding technique

Posted on January 30, 2016 by Matlab-Projects |

The dimensionality of light field data is typically very large for efficient implementation of sparse representation algorithms, such as for dictionary training and sparse coding. We propose a framework for…

An impact of grid based approach in offline handwritten Kannada word recognition

Posted on January 30, 2016 by Matlab-Projects |

The scanning of paper documents followed by the storage, retrieval, display, and management of the resulting electronic images, is known as document image processing, which is a subfield of DigitalImage Processing. The main objective of…

Solid model-based 3D pose measurement for ICF target positioning

Posted on January 30, 2016 by Matlab-Projects |

In Inertia Confinement Fusion (ICF) physical experiments, the accuracy of target positioning affects the successful rate of target hitting directly. A 3-CCD camera system is often used for tiny target…

Sonic Trampoline: How Audio Feedback Impacts the User’s Experience of Jumping

Posted on January 30, 2016 by Matlab-Projects |

To investigate how auditory augmentation influences user jumping activity on an elastic trampoline, the authors developed a system to interactively augment the trampoline’s sound. The system’s sound design is inspired…
