Title: Method and device for collating facial image
Inventor: TANIJIRI TOYOHISA
IPC: G06T7/00
Filed: 1999-05-25
Abstract: PROBLEM TO BE SOLVED: To improve the reliability of person identification of a facial image collating method which is applied to data processing at the time of performing the authentication, retrieval, etc., of persons by using facial image. SOLUTION: In the facial image collating method, unnecessary image data outside a face area are deleted by performing masking for extracting the facial area from two two-dimensional facial image (a collated image and a collating image) to be collated with each other based on prescribed mask data (S16) and erroneous assumption of a person caused by a difference in color information is prevented by performing monochromatization (S18). Then the fine structure (for example, wrinkles) of the face of the person is made to be inconspicuous by performing histogram smoothing processing (S20).

Title: Lighting system for railroad
Inventor: FUKUYAMA HIROSHI
IPC: B61L29/24
Filed: 1997-05-19
Abstract: PROBLEM TO BE SOLVED: To improve the visibility for the position of a railroad crossing and a span wire in case of bad weather or during the night by providing a light source for emitting light with such a wavelength that an operator of a vehicle is easy to find or flashing, and a light emitting means arranged on the upper side of the railroad crossing for emitting in a line or flashing light emitted from the light source. SOLUTION: An illuminating device for a railroad comprises a light source 1 and a linear light emitting means 2, wherein the light source 1 emits light with the optimum wavelength, and is stored in a light source box provided on a strut. The light emitting means 2 causes side light emission to emit light linearly, by which light supplied from the light source 1 to the inside of a core partly does not cause a total reflection phenomenon in the border with the inner peripheral surface of a clad to be transmitted intact through the inside of the clad and emitted from the outer peripheral surface to the outside efficiently.  Thus, even in case of bad weather such as rainfall or fog to be dark in the environment, or during the night, the position of the railroad crossing and the position of a span wire can be surely confirmed so as to remarkably improve the visibility and the safety of a vehicle's crossing the railroad crossing.
