摘要： An apparatus configured to discriminate the genuineness of a certified paper by exposing the paper to a light source and transporting the paper through an environment of an alternating-current electromagnetic field. Light detectors detect the light reflected from the paper and the light emitted by a fluorescent ink on the paper and output a waveform corresponding to the intensity of the detected light, reflected light, and the detected emitted light as the paper is scanned. The resulting waveforms are used to discriminate the genuineness of the paper. The fluorescent light and reflected light can be optically split and directed to separate detecting devices. Furthermore, the alternating-current electromagnetic field can be controlled by a voltage controller and configured to be driven only when the sensor detects light from the fluorescent ink.

摘要： A method for identifying an object image shown in a picture using density differences between an object image and a background. A screen taken by a camera is first divided into blocks; for each block, a Standard Object image is positioned based upon an arbitrary point on each picture; from the density differences in the picture, a normal vector of the outline portion of the Standard Object image is determined; then related vector data, that includes a position information up to a normal vector group and an angle information, is determined; the related vector data is stored as standard data in a block from which the normal vector is detected; a normal vector for a picture that shows an object image to be recognized is determined; from the normal vector, Answer points are determined based on standard data of the Standard Object image; and a focus point region comprised of Answer points is evaluated.
