Abstract : The human iris has been demonstrated to be a very accurate, non-invasiveand easy-to-use biometric for personal identification. Most of the currentstate-of-the-art iris recognition systems require the iris acquisition to beideal. A lot of constraints are hence put on the user and the acquisitionprocess.Our aim in this research is to relax these conditions and to develop a preprocessingalgorithm, which can be used in conjunction with any matchingalgorithm to handle the so-called non-ideal iris images. In this thesis wepresent a few robust techniques to process the non-ideal iris images so as togive a segmented iris image to the matching algorithm. The motivationbehind this work is to reduce the false reject rates of the current recognitionsystems and to reduce the intra-class variability. A new technique forestimating and compensating the angle in non-frontal iris images ispresented. We have also developed a novel segmentation algorithm, whichuses an ellipse-fitting approach for localizing the pupil. A fast and simplelimbus boundary segmentation algorithm is also presented.,.............-....,....-...,..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..
