Abstract: -Real-time Iris recognition systems are difficult to implement due to high processing time. Different steps of iris recognition process include segmentation, normalization and template creation and matching. Iris segmentation is the most time taking step in every iris processing application. Most iris processing implementations today employ low resolution iris image capture to keep the segmentation time within limits. This paper presents an enhanced iris segmentation method that allows iris recognition systems to be implemented in real-time applications. Reduced iris segmentation time further allows high resolution iris images to be used thereby enhancing recognition accuracy.
