  • Patent number: 8294765
    Abstract: This is a video image monitoring system which can effectively detect a mobile object appearing in a captured video image even if a background image and other camera condition change continuously. The video image monitoring system comprises: a video-image-capturing section 100 for putting out image data based on a video image signal obtained by using a camera 10; a mobile-object-candidate-area-detecting section 101 for extracting a candidate area of a mobile object from the image data; and a mobile-object-detecting section 102 for determining whether the candidate area is the mobile object. The mobile-object-candidate-area-detecting section 101 quantizes a brightness gradient direction of the image data, and calculates a spatio-temporal histogram which represents the frequency of a direction code appearing in a predetermined spatio-temporal space. After that, the mobile-object-candidate-area-detecting section 101 calculates a statistical spatio-temporal space evaluation value of the spatio-temporal histogram.

  • Patent number: 7078688
    Abstract: This invention is to provide a shape measuring device and a shape measuring method that can accurately measure a cross-sectional shape or a three-dimensional shape of a sample without using matching of characteristics. A shape measuring apparatus comprises a charged particle beam apparatus comprising a processor for measuring detected charged particles signal generated from the sample. The charged particle beam is irradiated to sample at first angle to generate a first signal and second angle to generate second signal. The processor selects a parameter indicating a relation between the first signal and a height of the sample or an inclination angle of the specimen until the first signal which achieves the second signal.

  • Publication number: 20060110029
    Abstract: A pattern recognizing method and apparatus are arranged to detect one or more objects with its own individuality belonging to the same category, such as a vehicle or a human's face, by using incremental signs in a manner to correspond with an apparent change caused by the posture variation of the object. For achieving the pattern detection corresponding with the apparent change caused by the posture variation of the object, the statistic quality of the incremental signs is extracted from a database having image data of the objects. The learning of a feature vector composed by using the quality makes it possible to design the most approximate identifier for detecting a pattern.

  • Publication number: 20040164243
    Abstract: An electron beam applied from an electron gun 1 and reflected off a surface of a specimen 7 placed on a stage 2 that is tilted at a tilt angle &phgr;=0 is detected, and a signal intensity thereof is measured by an electron detector 3. Based upon the measurement, an image processing unit 6 calculates a slope angle &thgr; of the surface of the specimen, and determines candidates for cross-sectional shape of the specimen. Signal intensity of the electromagnetic wave that would be reflected from a surface having a cross-sectional shape of each of the candidates if the tilt angle &phgr; were changed into &phgr;=&phgr;0 are estimated, and compared with a signal intensity actually measured by the electron detector 3 with the tilt angle &phgr; being changed into &phgr;=&phgr;0. Consequently, cross sectional shape and three-dimensional shape can be determined based upon a result of comparison, without utilizing a matching process of feature points.
