摘要： A method and apparatus for applying gradient edge detection to detect features in a biometric, such as a fingerprint, based on data representing an image of at least a portion of the biometric. The image is modeled as a function of the features. Data representing an image of the biometric is acquired, and features of the biometric are modeled for at least two resolutions. The method and apparatus improves analysis of both high-resolution images of biometrics of friction ridge containing skin that include resolved pores and lower resolution images of biometrics without resolved pores.

摘要： Photosensitizing dyes are often used in conjunction with a photoacid generator in photopolymerizable materials and in holographic recording media. Typical dyes for these materials are used in the region of the visible spectrum for wavelengths greater than about 450 run. The present invention discloses a number of new 1,4-alkynyl substituted napthalene photosensitizing dyes that have suitably low extinction coefficients coupled with good sensitizing properties for use in such materials at wavelengths in the visible spectrum region of about 400 nm.

摘要： Photosensitizing dyes are often used in conjunction with a photoacid generator in holographic recording media. Conventional photosensitizing dyes typically are limited by having an appreciable absorption of light when used in a sufficient concentration, such that the intensity of light decreases significantly with penetration into a recording medium. The present invention discloses a number of new 5-alkynyl substituted napthacene photosensitizing dyes that have low extinction coefficients coupled with good sensitizing properties, such that the problems associated with the photosensitizing dyes absorbing light are significantly reduced.

摘要： Disclosed is an optical disk, card or media which comprises: a) a plurality of data structures that are readable by the interrogating beam of light; and b) a composition on or in the optical disk, card or media disposed so that when the optical disk, card or media is used in the optical read-out system, the interrogating beam of light passes through the composition before or after contacting some or all of the data structures. The composition comprises a polymeric matrix with an organometallic complex dissolved therein or with metal, transition metal, metal oxide or transition metal oxide nanoparticles uniformly dispersed therein. The composition is substantially transparent to the interrogating beam and/or is substantially colorless. Alternatively, the composition comprises a solid polymeric matrix with an olefinic compound dissolved or uniformly dispersed therein wherein double bond in the olefinic compound undergoes oxidative cleavage promoted by a transition metal catalyst and a thiophenol or a catalytic amount of a thiyl radical and wherein the composition is substantially transparent to the interrogating beam and/or is substantially colorless.
