Study of facial image recognition based on a combined approach of preserving global and local features

Abstract

Biometrics is increasingly becoming important in this securityheightened newlineworld As the level of security breaches and transaction fraud newlineincreases the need for highly secure identification and personal verification newlinetechnologies is becoming apparent Though various biometric authentication newlineapproaches like fingerprint authentication iris recognition palm newlineauthentication and so on exist the increasing use of biometric technologies in newlinehighsecurity applications and beyond has stressed the requirement for highly newlinedependable face recognition systems Most of the existing face recognition newlinealgorithms can be categorized into featurebased approaches and appearancebased newlineapproaches Appearance based approaches consider each pixel in an newlineimage as a coordinate in a highdimensional space while the former extracts newlinethe features as the representation of whole image using various feature newlineextraction techniques newline newline
