摘要:
An authentication system incorporates pluralilty of fused biometric modalities which are combined with quality indicia of the biometric samples. Fusion processing maps individual modality data along with one or more quality measurements to a fused score for purposes of making an authentication decision.

A system, method and apparatus for performing a facial approximation is described. The system includes an acquisition subsystem and a facial approximation algorithm. The method includes the steps of acquiring models of known skulls and a model of a questioned skull, comparing the models of the known skulls with the model of the questioned skull, and removing variation in the facial structure of the questioned skull due to skeletal variation between the known skulls and the questioned skull. The apparatus includes a bony structure software component, a bony structure warping software component, and a soft tissue software component.

A system, program product, and method to perform automated three-dimensional image registration of a part within an inspection cell, are provided. The system can include a laser-ultrasound inspection device having a scanning head to generate ultrasonic surface displacements in a part, an inspection laser, and an interferometer to collect phase modulated light reflected by the part. The system can also include a part position locator positioned to measure a distance between points on a surface of the part and a scanning laser reference location. The system can also include a database containing computer-aided design models for each part of interest, and a model of the inspection cell. The system can further include a laser ultrasound inspection computer communication with the laser-ultrasound detection device and the part position locator, and laser ultrasound inspection program product adapted to perform automated three-dimensional image registration of the part.

摘要:
The present invention provides a multi-mode calibration target operable to calibrate multiple optical sensors. One embodiment has multiple planar surfaces, wherein the multiple planar surfaces are able to be distinguished by visual sensors based on their color, hue, shade, tint, or tone. Additionally, these planar surfaces may be raised or recessed from one another to provide depth contrast as well as visual contrast. Other embodiments may include narrow band emitters such as laser diodes located at predetermined locations within the multi-mode target. These targets may then be used to calibrate various sensors, such as optical sensors, within an inspection system such as a laser ultrasonic inspection system.
