Abstract: A method for identifying an iris image can include obtaining an iris image of an eye, segmenting the iris image, generating, from the segmented iris image, a normalized iris image, and generating, from the normalized iris image, an iris template. The method can also include generating a modified iris template by extracting a portion of the iris template, comparing the modified iris template with a plurality of previously stored other modified iris templates and matching the modified iris template with one of the plurality of previously stored other modified iris templates. The method can also include generating a modified iris template by extracting a portion of the iris template, comparing the modified iris template with a plurality of previously stored other modified iris templates, and matching the modified iris template with one of the plurality of previously stored other modified iris templates.

Abstract: A method and apparatus for designing an iris biometrics system that operates in minimally constrained settings. The image acquisition system has fewer constraints on subjects than traditional methods by extending standoff distance and capture volume. The method receives design parameters and provides derived quantities that are useful in designing an image acquisition system having a specific set of performance requirements. Exemplary scenarios of minimally constrained settings are provided, such as a high volume security checkpoint, an office, an aircraft boarding bridge, a wide corridor, and an automobile.

Abstract: A method and apparatus for obtaining iris biometric information that provides increased standoff distance and capture volume is provided herein. In one embodiment, a system for obtaining iris biometric information includes an array of cameras defining an image capture volume for capturing an image of an iris; and an image processor, coupled to the array of cameras, for determining at least one suitable iris image for processing from the images generated for the image capture volume. The image capture volume may include a plurality of cells, wherein each cell corresponds to at least one of the cameras in the array of iris image capture cameras.

Abstract: A method and apparatus for strobed image capture includes stroboscopic illumination synchronized with one or more cameras to improve a signal to noise ratio, reduce motion blur and avoid object damage in sensor systems used to analyze illumination sensitive objects.
