  • Patent number: 7957567
    Abstract: A partial image is cut out from an input image. A first classifier judges whether the partial image includes a face facing a direction within a first angular range. Another classifier judges whether the partial image includes a face facing a direction within another angular range that partially overlaps with the first angular range. The partial image is judged to include a face facing a direction within a specific angular range, which is the first angular range from which the portion that overlaps with the other angular range has been removed, if the first classifier judges that the image includes a face facing a direction within the first angular range, and the other classifier judges that the image does not include a face facing the second angular range. Each classifier is generated by machine learning, and judges whether images include faces facing directions corresponding to predetermined angular ranges.

  • Patent number: 7812961
    Abstract: Image quality of tomographic images obtained by optical tomographic measurement is improved. Spatial frequency processes are administered on a tomographic image, with the frequency processing properties (high frequency gain) in the scanning direction of a measuring light beam set to be lower than the frequency processing properties (high frequency gain) in the direction of the optical axis of the measuring light beam. For example, a smoothing process that removes high frequency components is administered to the tomographic image only in the scanning direction. Alternatively, a sharpening process that emphasizes high frequency components is administered to the tomographic image only in the direction of the optical axis.

  • Patent number: 7742570
    Abstract: An entire area of an FPD on which an alignment marker provided in a screen is projected is set in advance as a fixed overlapping area (Ctop to Cbottom) according to the long length imaging area and/or the X-ray source position. When determining a plurality of field-of-view area areas for dividing an imaging area for long length imaging into a plurality of areas and taking images, the field-of-view areas (FOVNT to FOVNB) and the FPD positions PN corresponding to the respective field-of-view areas are determined so that adjacent field-of-view areas overlap each other at the set fixed overlapping area. The X-ray source height, the X-ray irradiation direction, the collimator aperture angle and the FPD position are controlled so as to apply an X-ray only to each of the determined field-of-view areas.

  • Publication number: 20100067773
    Abstract: For a radiographic image detector which includes an imaging plane including two-dimensional matrix of pixel sections, each pixel section storing, when exposed to radiation, a charge according to amount of the radiation, and which is used to be exposed to radiation transmitted through the same subject each time the detector is shifted along a predetermined axis of shift, an inclination of the two-dimensional matrix relative to the axis of shift of the radiographic image detector is detected. The inclination is detected by applying radiation two times to the detector at different radiation application positions effected by the shift of the detector so that a common marker is imaged during each radiation application; carrying out a reading operation after each radiation application to acquire image data representing image information of the marker; and detecting the inclination based on a positional relationship between marker images represented by the image data.

At least one of a plurality of types of classifiers, each type of classifier judging each of a plurality of predetermined states of a predetermined subject, is employed to discriminate the state of the subject within the obtained image. At least one state is predicted for the subject within the obtained image, based on stepwise changes of the state of the subject obtained by previously discriminated states within temporal series images preceding the obtained image. The classifier corresponding to the predicted state is prioritized or weighted, when applying the classifiers to perform discrimination.

  • Patent number: 7311889
    Abstract: The invention provides a process for production of carbon nanotubes whereby a laminate prepared by alternating lamination of a metal catalyst and a material other than the metal catalyst is cut to expose the laminated structure, and carbon nanotubes are grown on the metal catalyst at the cut surface of the laminate. The process results in high-quality carbon nanotubes, with minimized bundle growth, which are each individually and independently arranged in a highly precise manner at prescribed locations. The invention also provides a carbon nanotube production process comprising a step of preparing a substrate which is inclined in one or two dimensions from a specific highly symmetrical crystal orientation and vapor depositing a metal catalyst along the atomic steps appearing on the surface of the substrate, and a step of growing the carbon nanotubes by chemical vapor deposition (CVD) using the metal catalyst as nuclei.
