Abstract

One of the difficult tasks in iris recognition is to detect the boundary between the iris region and the pupil region. This is due to the low texture contrast between them. In order to capture the degree of texture contrast between iris region and pupil region, we propose a novel algorithm that hybrid a difference function with a factor matrix. Experiments show that this algorithm can detect the boundary between iris region and pupil region accurately. Based on this algorithm, the percentage of successful segmentation is 99.34%.
