  • Patent number: 8744139
    Abstract: An apparatus, method and system are provided for sensing at least one biometric measure of an individual. An electrical current flows through an electrode to induce an electromagnetic field. The electromagnetic field stimulates and excites the molecules associated with the sweat gland pores and causes molecular compounds to fluoresce. An image of the fluoresced dermal surface is obtained and a biometric function is performed with data derived from the image. Alternatively, sweat gland pore biometric information may be derived from variations, fluctuations or disturbances to the electromagnetic field induced by the electrical current.

  • Patent number: 8712119
    Abstract: Described herein is a computer-aided technology for facilitating detection of folds of an object surface. In one implementation, image data is processed to determine curvature characteristics at one or more points of the surface of a region of interest. If the curvature characteristics of one of the one or more points correspond to a hyperbolic curvature, the point is identified as a seed point. A region of a predetermined thickness is grown around the seed point so as to detect the presence of any fold feature within the grown region.

  • Patent number: 8693784
    Abstract: An eyelid detection device that, based on first order differential values and second order differential values of vertical density change at an eyelid boundary in an eye image, shifts the second order differential values upwards by ¼ of the cycle of density change frequency of an eyelid boundary and combines the first order differential values and the second order differential values to compute upper eyelid feature amounts. The eyelid detection device detects a boundary between an upper eyelid and eyeball based on peak points in the vertical direction of the computed upper eyelid feature amounts. Consequently, the boundary between an eyelid and eyeball can be accurately detected even when the eyelid has been applied with makeup.

  • Patent number: 8682057
    Abstract: Method, computer program product, and apparatus are provided for identifying a graphic symbol within an image obtained by optical scanning. An image intensity is measured for each of a plurality of columns of the image, wherein each column has a length that extends across the graphic symbol in a first direction, and wherein the plurality of columns collectively extend across the graphic symbol in a second direction. The graphic symbol is then identified by matching a profile of the image intensity to a predetermined image intensity profile associated with a given graphic symbol. Optionally, the image is a digital image and the image intensity for each column is the sum of the image intensity for each pixel in that individual column. An image intensity differential between adjacent columns may be calculated for matching with a predetermined differential profile or comparison with an electronic profile generated by a magnetic scan.

  • Patent number: 8670624
    Abstract: Analysis filter processing is recursively repeated on horizontal and vertical low frequency component coefficients obtained as a result of the analysis filter processing, until a predetermined decomposition level is reached. Coefficients obtained during a process of computation in the analysis filter processing and, except for a preset decomposition level, horizontal and vertical low frequency component coefficients obtained as a result of the computation in the analysis filter processing are stored in a first storage section independently for each decomposition level. The coefficients stored in the first storage section are read as appropriate and the read coefficients are supplied for the analysis filter processing. The horizontal and vertical low frequency component coefficients of the preset decomposition level are stored in a second storage section. The coefficients stored in the second storage section are read as appropriate. The read coefficients are supplied for the analysis filter processing.

  • Patent number: 8655032
    Abstract: A mobile application stored within the mobile device allows for file collection, transfer, and display on a smart device with G3, G4, EDGE, or similar data communication capabilities. The software is used in conjunction with information collection devices synced to a smart device via blue tooth technology, such as a fingerprinting device. The device will transfer a file to the smart device running the mobile application. The application will then encrypt the file and encode the file that is then packaged into a proprietary format. The file is then sent to a web location using the data transmission capability of the mobile device. The device will then monitor a file location of a web address for a return response. It will then get the file from the web location in a standard NIST approved format, extract information and images from the file, displaying them in a GUI.

  • Patent number: 8630474
    Abstract: For filtered back-projection of a projection image data set, the projection image data set is cosine-weighted. The cosine-weighted projection image data set within the image plane of the projection image data set is subjected to a two-dimensional Radon transformation. The Radon transform of the cosine-weighted projection image data set differentiated with respect to the distance from an image origin of an image coordinate system. The derivative of the Radon transform is redundancy-weighted. The redundancy-weighted derivative is subjected to a two-dimensional Radon back-transformation. The Radon back-transform is differentiated and back-projected with respect to an image column coordinate. A differentiation step width entering into the differentiation is varied depending on depth.

  • Patent number: 8588510
    Abstract: When a detection-target subject is imaged with an image pickup device having line-defect pixels, the detection-target subject is imaged, with the image pickup device or the detection-target subject rotated at a predetermined angle so that the edge of one side of the detection-target subject is not parallel to each of horizontal and vertical scanning lines of the image pickup device, and a gray-scale image is captured by a control apparatus. In the gray-scale image, the luminance of each of the line-defect pixels is corrected by interpolation with luminances of pixels adjacent to both sides of the line-defect pixel. The gray-scale image is subjected to sub-pixel processing to detect the edge of the detection-target subject. When the detection-target subject is a component in a rectangular shape, rotation is made so that four sides are not parallel to each of the horizontal and vertical scanning lines of the image pickup device.
