Abstract

The uniqueness of the iris makes it an effective physiological biometric trait which helps in personal identification. In an iris-based personal identification system, image enhancement plays a vital role. An apt enhancement will help in the proper localization of iris in the image. This paper proposes a pyramid-based image enhancement through multi-scale image processing. It can increase the contrast of the image to compensate for the illumination problem, compared to existing methods. A comparative analysis with CLAHE and divide-and-conquer method is also performed in this paper. Simulation results show that the proposed method gives promising results.
