A New Methodology For Segmentation Of Iris
Iris found in an eye image forms the important biometric feature in a human body. The biometric feature can be
used for authentication thus forms the necessity for feature extraction. This paper proposes new methodology for iris
segmentation. Hence iris is extracted from an eye image and it is subjected to image processing which includes segmentation
.The segmentation is a process which usually involves resizing, color to grey conversion or to binary conversion and
thinning of the image. Thinning of an iris image refers to converting a thick image signal to thick image signal. Thinning
also referred to as skeletalization. once iris is extracted from an eye image basic image processing is done then segmentation.
Segmentation forms the major part as eye image contains abundant information which is not required.
