Some fields updated by batch processes.Title from page 1, viewed March 13, 2007.The Slap Fingerprint Segmentation Evaluation 2004 (SlapSeg04) was conducted to assess the accuracy of algorithms used to segment slap fingerprint images into individual fingerprint images. Thirteen slap segmentation applications from ten different organizations were evaluated using data from seven government sources. The source of data, the segmentation software used, and the scoring criteria used were each found to have a significant impact on accuracy. The most accurate segmenters produced at least three highly matchable fingers and correctly identified finger positions in from 93% to over 99% of the slap images, depending on the data source. The data source had a much greater effect on success rate than whether the images were collected using livescan devices or paper. Most segmenters achieved comparable accuracies on the better quality data, but there were significant differences among segmenters when processing poor quality data. Some segmenters are capable of identifying many, but not all, problem slaps: failure rates could be cut substantially by allowing some of the slaps to be recaptured or rejected.FingerprintsIdentificationAutomationImage processingTestingFingerprintsIdentificationAutomation.Image processingTesting.Hicklin R.

The coverage encompasses light alloys such as aluminum-, magnesium-, and titanium-based alloys, including titanium aluminides; steels; superalloys; oxide dispersion strengthened alloys; refractory alloys; and related systems such as laminate composites. In each chapter, materials properties and relevant technological aspects, including processing, are presented. Individual chapters focus on coatings for gas turbine engines and hot corrosion of alloys and coatings. Readers will also find consideration of applications in aerospace-related fields. The book takes full account of the impact of energy saving and environmental issues on materials development, reflecting the major shifts that have occurred in the motivations guiding research efforts into the development of new materials systems. Aerospace Alloys will be a valuable reference for graduate students on materials science and engineering courses and will also provide useful information for engineers working in the aerospace, metallurgical, and energy production industries.Topics in Mining, Metallurgy and Materials Engineering,2364-3307Building materialsAerospace engineeringAstronauticsSurfaces (Physics)Automotive engineeringCoatingsTribologyStructural MaterialsAerospace Technology and AstronauticsSurface and Interface and Thin FilmAutomotive EngineeringCoatingsTribologyBuilding materials.Aerospace engineering.Astronautics.Surfaces (Physics)Automotive engineering.Coatings.Tribology.Structural Materials.Aerospace Technology and Astronautics.Surface and Interface and Thin Film.Automotive Engineering.Coatings.Tribology.669.94669Gialanella Stefanoauthttp://id.loc.gov/vocabulary/relators/aut1061991Malandruccolo Alessioauthttp://id.loc.gov/vocabulary/relators/autMiAaPQMiAaPQMiAaPQBOOK9910366602803321Aerospace Alloys2521743UNINA
