Currently, most iris recognition systems require a cooperative subject with frontal high quality iris image to obtain a descent recognition result. However, for a noncooperative subject who may be facing away from the camera, the obtained iris image may be blurry, deformable, or highly occluded. As a result, only a portion of the iris information may be extracted (a partial iris). Partial iris pattern analysis would be an important step for noncooperative subject iris recognition. Little researc...

The authors present a new algorithm for iris recognition. Segmentation is based on local statistics, and after segmentation, the image is subjected to contrast-limited, adaptive histogram equalization. Feature extraction is then conducted using two directional filters (vertically and horizontally oriented). The presence (or absence) of ridges and their dominant directions are determined, based on maximum directional filter response. Templates are compared using fractional Hamming distance as a m...

A one-dimensional approach to iris recognition is presented. It is translation-, rotation-, illumination-, and scale-invariant. Traditional iris recognition systems typically use a two-dimensional iris signature that requires circular rotation for pattern matching. The new approach uses the Du measure as a matching mechanism, and generates a set of the most probable matches (ranks) instead of only the best match. Since the method generates one-dimensional signatures that are rotation-invariant, ...
This paper describes the US Naval Academy's outreach program called Summer Seminar, which offers the opportunity for high school seniors to participate in one of three six-day sessions to experience life as a midshipman, both academically and otherwise. This paper focuses on the workshop on electrical engineering in 2005, wherein approximately 360 of the total 1,855 high school students attended. The electrical engineering workshop began with an introduction to the fundamentals of electrical the...

Biometrics is an emerging field of technology using unique and measurable physical, biological, or behavioral characteristics that can be processed to identify a person. It is a multidisciplinary subject that integrates engineering, statistics, mathematics, computing, psychology, and policy. The need for biometrics can be found in governments, in the military, and in commercial applications. The Electrical Engineering Department at the U.S. Naval Academy, Annapolis, MD, has introduced a biometri...

National security today requires identification of people, things and activities. Biometrics plays an important role in the identification of people, and indirectly, in the identification of things and activities. Therefore, the development of technology and systems that provide faster and more accurate biometric identification is critical to the defense of our country. In addition, the development of a broad range of biometrics is necessary to provide the range of options needed to address flex...

In this paper, we investigate the accuracy of using a partial iris image for identification and determine which portion of the iris has the most distinguishable patterns. Moreover, we compare these results with the results of Du et. al. using the CASIA database. The experimental results show that it is challenging but feasible to use only a partial iris image for human identification.

Iris recognition is a proven, accurate means to identify people. Commercial iris recognition systems are currently employed to allow passengers in some airports to be rapidly processed through security, to allow access to secure areas, and for secure access to computer networks. With the growing employment of iris recognition systems and associated research to support this, the need for large databases of iris images is growing. If required storage space is not adequate for these images, compres...

A biometric is a distinct, robust, and measurable physiological characteristic of a person which can be used to identify, or verify their identity. Additionally, the term biometrics refers to the automated recognition of an individual using one or more of these characteristics. The more commonly used biometrics includes fingerprints, face, and iris. Biometrics has proven to be a solution to a number of security-related applications where accurate identification or verification of individuals is ...
