Abstract :
This paper introduces a new iris segmentation approach based on correlation filters. The iris boundaries are detected using an original technique of composite filter called indexed composite filters. For each of the iris boundary detection, an indexed composite filter is generated using a database of circular contours corresponding to all boundary radius possible values. Experimental results of pupil and iris outer boundary localization on the CASIA iris database demonstrate the promising performance of this method.
