Facial Recognition Biometrics

IntroductionTraditional someoneal denomination and au then(prenominal)tication methods always have the riskiness of existence stolen , duplicated or forgotten . Hence biometrics was introduced as an denomination and authentication technology , where physical features would be utilize for recognizing a person . This technology uses many features for unique identification alike(p) fingermarks , lay out , irises and voice . Fingerprints be by removed the most popular techniques used for i8dentification , because of their traditional use in forensics . However , slip citation is considered to be the more use out , friendly and convenient method for identification as compared to fingerprint identification . This has do face comprehension trunk as the second most widely used biometric technology after(prenominal) finger printing with a projected revenue of 429 million in 2007 according to Raicu Strandburg (2005 . This growth in the use of this technology is attributed to the perspicacious rise in the number of digital cameras and camcs and inconsequence on the qui vive camerasThe purpose of this is to analyze this technology , explain its canonic hold of faith , look into the limitations of the technology and the research work existence do in this fieldFace RecognitionFace perception consists of two grades : face maculation and attitude features root and face designation . hear to a lower place shows a flow chart of the face recognition frameFig -1 Flow chart of a base face recognition arranging (Zhang , 2000Face perception and Location - This step checks if the given go for or im years sequence includes faces . It yes , then it locates the position of the faces and segments each face from the terra firmaFeatures extraction and face recognition - This step checks the various features that distinguish antithetical ind! ividuals . It figures whether the people in the image are the given person or if he / she are in the databaseNeedless to assure , the face recognition system depends upon the commentary of the system . The importance of the scuttlebutt and get wind background is explained by Zhang (2000 ) by giving the sideline example .

The picture taken during log in on a system and passing custom are controlled . That is to say the background is equal for the images or image sequences The pose , druthers etc is as well as know and well controlled . This makes the cover of face recognition is accurate and speedy . However , in case of an input environment which is general for all situations , there readiness be number of faces and also a complex background . The mend of the face and its size of it is not known , the illumination on the several(predicate) faces in a picture is different and their expressions might be different too . In such cases , the face detection and location is difficult . Face recognition butt be made difficult due to different expressions orientations and age , making the process of feature extraction and face recognition all the more difficult (Zhang , 2000One important parameter in the evaluation of a face-processing system is the performance evaluation . The basic measurement parameters are the same as that for pattern recognition system FA i .e . assumed acceptance or bastard positive and FR i .e . false rejection or false negative .
