摘要： A system and method for performing an identity search in a database of iris images for a probe iris image includes generating a full-length iris code and a compact iris code for iris images in a database, and generating a full-length iris code and a compact iris code for a probe iris image. The compact iris code for the probe image is scored against all compact iris codes in the database. A fraction of the database is retained based on score data. The full length iris code for the probe image is scored against all the full length iris codes in the retained portion of the database.

摘要： A system and method for generating compact iris representations based on a database of iris images includes providing full-length iris codes for iris images in a database, where the full-length iris code includes a plurality of portions corresponding to circumferential rings in an associated iris image. Genuine and imposter score distributions are computed for the full-length iris codes, and code portions are identified that have a contribution that provides separation between imposter and genuine distributions relative to a threshold. A correlation between remaining code portions is measured. a subset of code portions having low correlations within the subset is generated to produce a compact iris representation.

摘要： This invention provides for the automatic determination of a human's gaze angle. The gaze angle is assumed to be the same as the head angle (i.e., eyes looking straight ahead). It is determined by comparing the observed eye separation relative to a maximal eye separation. The gaze angle is then determined to be the inverse cosine, or arc cosine, of the ratio of these two measurements.

摘要： The biometric system disclosed herein comprises device for providing a pattern; the device having a source of light and a source for providing a pattern. The source of light is operative to illuminate an object with light. An imaging device is disposed at a different location from the source of light to capture an image from the object. The system further comprises a pattern comparison device; the pattern comparison device being operative to compare details of the pattern disposed upon the object and details of a reference pattern; the pattern comparison device rejecting the object if the pattern disposed upon the object does not match the reference pattern.
