Abstract : Of the many biometrics that exist, iris recognition is finding more attention thanany other due to its potential for improved accuracy, permanence, and acceptance.Current iris recognition systems operate on frontal view images of good quality. Dueto the small area of the iris, user co-operation is required. In this work, a new systemcapable of processing iris images which are not necessarily in frontal view is described.This overcomes one of the major hurdles with current iris recognition systems andenhances user convenience and accuracy. The proposed system is designed to operatein two steps: (i) preprocessing and estimation of the gaze direction and (ii)processing and encoding of the rotated iris image. Two objective functions are usedto estimate the gaze direction. Later, the o-angle iris image undergoes geometrictransformations involving the estimated angle and is further processed as if it werea frontal view image. Two methods: (i) PCA and (ii) ICA are used for encoding.Three dierent datasets are used to quantify performance of the proposed non-idealrecognition system.iii,.............-....,....-...,..tested for theQ1 PC1 bus cardBoth these projects mere sofixare des elopment efforts tonards contributing to dlfferentaspects of Roboucs and lZ1echatronics projects m the Controls and Roboucs Group..
