Iris recognition is an established and successful biometric technology. It is used in clearing travelers in the UK, for border control in the UAE, and as a part of India`s Unique ID program. However, there are still significant challenges to be addressed as iris recognition matures to successfully handle ongoing national-scale applications. Our recent work has documented challenges involving pupil dilation, the wearing of contact lenses, and other factors. We propose to conduct research that (a) creates a better understanding of the challenges that pupil dilation, contact lenses, and Lasik operations present for iris recognition performance, and (b) based on this understanding, develops algorithms and approaches to mitigate the effects of these challenges. We will conduct iris recognition experiments and analyze the results in order to document the effects of dilation, contact lenses and Lasik, and to understand how the range of how these factors present themselves in different instances. We will then develop and implement algorithms and approaches to mitigate the effects of these factors, and perform experiments that document and measure the improvement in iris recognition performance. We expect that solutions such as those that we develop will become a standard element of all commercial iris biometric systems.

Currently, SCBA lenses are made from high-heat polycarbonate with a maximum service temperature rating of 275 deg F to 383 deg F. However, first responders may encounter temperatures due to fire reaching 1000 deg F to 1400 deg F at face level with a heat flux density of about 2.2 W/sq-cm. Developing a more durable, high-heat resistant lens will significantly improve firefighter safety and enable firefighters to function effectively in more severe environments than with current SCBAs. MPR Associates, Inc. will work with Scott Health and Safety to identify candidate test materials based on the material`s ability to provide increased durability, clarity, resistance to impacts, and improved heat resistance. A test plan and test procedures will be developed based on current and future (i.e., planned) industry accepted standards (e.g., NIOSH, NFPA, EN). Testing will emphasize the ability of test materials to withstand the extreme heat generated by compartmentalized fires. Commercialization of a high temperature face piece will take advantage of the economy of scale due to the potentially large government and commercial customer base, thus providing a viable improvement for DHS and other users of SCBAs. The improved face piece also could be back-fit to SCBAs currently in use.
