Image Segmentation and Impainting
Noise removal is an important problem for iris recognition. If the iris regions were not correctly segmented in
iris images, segmented iris regions possibly include noises, namely eyelashes, eyelids, reflections and pupil.
Noises influence the features of both noise regions and their neighboring regions, which will result in poor
recognition performance. To solve this problem, this paper proposes a method for removing noises and impainting
iris images. The whole procedure includes three steps: 1) localization and normalization, 2) noise removal based
on phase congruency, and 3) iris image impainting. A series of experiments show that the proposed method has
encouraging performance for improving the recognition accuracy.
