- Abstract
This study focuses on the location of the iris using the Circular Hough Transform. We propose an improved iris boundaries location method on two main steps. First, possible candidates are obtained by applying edge detection. In order to remove unwanted candidates, first, image resize using bicubic interpolation is performed, then edge detection and mathematical morphology. To detect the presence of the circular shapes corresponding to the inner and outer iris boundaries, Circular Hough Transform is applied. The results of the experiments performed on an iris image database proved that the proposed method have encouraging performance. The method is robust, provides a reduced computational time, and the location is automatic.
