Introduction

Basics of Audio Compression
Advances in digital audio technology are fueled by two sources: hardware developments and new signal processing techniques. When processors dissipated tens of watts of power and memory densities were on the order of kilobits per square inch, portable playback devices like an MP3 player were not possible. Now, however, power dissipation, memory densities, and processor speeds have improved by several orders of magnitude. Advancements in signal processing are exemplified by Internet broadcast applicati ....etc

This seminar aim to extract ear shape features for recognition Active Shape Models (ASMs) is applied to model the shape and local appearance of the ear in a statistical manner. In addition, steerable features are extracted from the ear image ahead of ASMs. Steerable features encode rich discriminate information of the local structural texture and provide accurate guidance for shape location. Eigenearshape is used for final classification. Experiments on an ear database show an encouraging performanc ....etc

Latest Invention: Acoustic Ear-scanning Technology to Help Avoid Theft



Researchers managed to come up with a technology that could protect portable devices such as iPod and mobile phones from theft.
Their latest invention uses the acoustic fingerprint of the ear, which makes it impossible for other people to operate the device. Such technology could be also used to improve the safety features of bank accounts and passports.
Scientists found that it is possible to identify a person by the distinctive sounds ....etc

Abstract
TV, radio, GPS, cell phones, wireless Internet, and other electronics all use different radio waves to receive and send information. Now scientists at MIT have created a tiny chip capable of receiving any radio signal, based on the human ear.

The new universal radio could lead to better reception and a new class of electronics that can pick up any radio frequency.

The human ear is a very good spectrum analyzer, said Rahul Sarpeshkar, a professor at MIT who co-authored the paper in the June issue of the IEEE Journal of S ....etc

Abstract
The ear is a promising candidate for biometric identification. However, in prior work, the pre-processing of ear images has had manual steps, and algorithms have not neces- sarily handled problems caused by hair and earrings. This seminar present a complete system for ear biometrics, including automated segmentation of the ear in a profile view image and 3D shape matching for recog- nition. and evaluated this system with the largest experimental study to date in ear biometrics, achieving a rank-one recognition rate of 97.6%.for ear ....etc

Abstract

In this electronic age the issue of identification is no longer confined within the walls of Penitentiary. In today’s scenario where computers, CCD cameras and other sophisticated electronic gadgets are invading every nook and corner, personal identification has emerged as a global problem.

There is an ever-growing need to authenticate individuals. Conventionally, one establishes his identity using passports, identity cards, keys, or by remembering passwords and personal ide ....etc

Is this the person who he or she claims to be? Nowadays this question arises incessantly. In different organizations like financial services, e-commerce, telecommunication, government, traffic, health care the security issues are more and more important. It is important to verify that people are allowed to pass some points or use some resources. The security issues are arisen quickly after some crude abuses. For these reason, organizations are interested in taking automated identity authenticati ....etc
