% function: EER_DET_conf
%
% DESCRIPTION:
% It plots traditional curves and gives also some interesting values in
% order to evaluate the performance of a biometric verification system.
% The curves are:
% - Receiver Operating Characteristic (ROC) curve
% - Detection Error Trade-off (DET) curve
% - FAR vs FRR
% The values are:
% - Equal Error Rate (EER) which is computed as the point where
% FAR=FRR
% - Operating Point (OP) which is d ....etc

I have a database of eye images for which i have generated a feature vector database,now i am taking a query image as input and calculating its feature vector and comparing it with the feature vectors stored in the feature vector database.after compairson i am displaying the top 5 closest images.and now i want to write a code for calculating FAR and GAR. I dont have any idea about how i can do it. please just give me some hints so that i can do it myself. ....etc

HIGH THROUGHPUT AND LOW POWER REED SOLOMEN DECODER FOR ULTRA WIDE BAND FREQUENCIES

Abstract:- Reed Solomon (RS) codes have been widely used in a variety of communication systems such as space communication link, digital subscriber loops and wireless systems, as well as in networking Communications and magnetic and data storage systems. Continual demand for ever-higher data rates and storage capacity makes it necessary to devise very high-speed implementations of RS Decoders. Newer and faster implementations of the decoder are being developed ....etc

The most important development in the computer communications industry in the 1990s is the evolution of the integrated services digital network (ISDN) and broadband ISDN (B-ISDN). The ISDN and B-ISDN have had a dramatic impact on the planning and deployment of intelligent digital networks providing integrated services for voice, data and video. Further, the work on the ISDN and B-ISDN standards has led to the development of two major new networking technologies; frame relay and asynchronous transfer mode (ATM). Frame relay and ATM have become t ....etc

Abstract;
In order to examine the validity of model at organic/metal interfaces, the position of the vacuum level of N,N'-bis(3-methylphenyl)-N,N'-diphenyl--4,4'-diamine (TPD) film formed on various metal substrates (Au, Cu, Ag, Mg and Ca) was measured as a function of the film-thickness by Kelvin probe method in ultrahigh vacuum (UHV). TPD is a typical hole-injecting material for organic electroluminescent devices. At all the interfaces, sharp shifts of the vacuum level were observed within 1 nm thickness. Further deposition of ....etc

ABSTRACT

Mankind has come across many stages right from ancient Stone Age to the modern wireless age. In every stage it developed its own unique method of communication to suit its requirements. These methods range from Graham Bell s cabled telephones to today s wireless mobile handsets. But if there could be a technology such that the waves co ....etc

INTRODUCTION

The average person has a small home, but a huge appetite for entertainment. All of us would want to zap video images from digital camcorders to our hard drives without tripping over the cables that connect them. As home entertainment systems become more sophisticated, u will have flat panel displays. You could hang them like paintings on your wall ..Now who would want cables to dangle from those beauties?

So you think - big deal . We have Bluetooth and 802.11 wireless technologies to solve this problem. They do a decent j ....etc
