Title: Two methodologies for iris detection and location in face images
Issue Date: 2007
Abstract: In this paper two methodologies todetect and locate the iris of the eye in static images, are pre-sented. One uses the Houghs transform and other is based on deformable templates. In both methodologies, the contour of the iris is represented geometrically by a circumference and its radius and centre are considered as its control parameters. The dynamic update of these parameters allows the determination of its final values, enabling the fully definition of the iris in the image. After a description of the considered methodologies, the advantages and disadvantages between them are presented, as well as some experimental results, conclusions and perspectives of future work.
