A New Shape-Based Iris Recognition

This paper presents a new shape-based iris recognition method. The new method utilizes intensity patterns formed by physical iris structures such as crypts and naevi. These structures appear as regions with heavily dark pigmented blobs. We purpose a modified thresholding technique called quotient thresholding, The thresholding is used for analyzing and segmenting the iris features. Shape information of these segmented features is measured by fitting four different circles onto the segmented features. Our experiments indicate interesting and promising results
