  • Publication number: 20170272646
    Abstract: Processing for judging whether a face is included in a frame is performed, in a predetermined interval, on each of frames included in a moving image of a subject, displayed on a monitor, until the judgment becomes positive. If it is judged that a face is included in a frame, the facial position is detected in the frame, and stored. Then, judgment is made as to whether a face is included in the next frame after predetermined time. If the judgment is positive, the facial position is detected. The previously stored facial position is replaced by the newly detected facial position, and the newly detected facial position is stored. These processes are repeated until photographing operation is performed by operating a release unit.

  • Publication number: 20170159208
    Abstract: The object is to produce with good reproducibility an epitaxial silicon carbide wafer having a high quality silicon carbide single crystal thin film with little step bunching. To achieve this object, for etching the silicon carbide single crystal substrate in the epitaxial growth furnace, hydrogen carrier gas and silicon-based material gas are used. After the etching treatment is finished as well, the epitaxial growth conditions are changed in the state in the state supplying these gases. When the conditions stabilize, a carbon-based material gas is introduced for epitaxial growth.

  • Publication number: 20170109852
    Abstract: Disclosed is a system whereby it is possible to verify the safety of a person even if the person is not aware that the person is being searched for as a missing person. In this system, each verification requesting person who is searching for another person registers, in a database of a portal server (4), a set comprising a feature value of the face of the searched-for person and personal information (e.g., telephone number) about the searched-for person or the verification requesting person. A field server (2) constantly compares feature values of captured face images with the database, and if a close match is found between the feature value of a captured face image and the stored feature value of the face of a person, the field server (2) presents the registered personal information associated with that person to the person from which the captured face image was derived and requests verification from the latter person.

  • Patent number: 9589181
    Abstract: Provided is a suspicious person detection method. First, a normal similar facial image search is carried out. Next, facial images, which are detected automatically from the input images and specified manually, are specified to be determined. Next, similar faces are searched for limited time on a time axis on the database. Next, the number of search results that distance between the features is lower than predetermined value is calculated and it is determined that the number of appearances is large and a possibility of a prowling person is high if the number of cases is large, and otherwise a possibility of prowling person is low. Last, a similarity between a facial image of a pre-registered residents and a facial image of a person whose number is large is calculated, and it is re-determined that the person is residents if the similarity is high, regardless of the determination.

  • Patent number: 9443150
    Abstract: A technique is proposed for enabling stable detection of an object even when the contrast of an image is lowered overall or partially. A preprocessing section 12 is added to the upstream stage of an object detecting processing section 13, and provides an obtained corrected image (image obtained by subjecting an input image to contrast enhancement) as an input image for the object detecting processing section 13. This facilitates the detection of the object even when the contrast of the entire screen is lowered due to fog or rain. Furthermore, the object detecting processing section 13 detects the object by using not only the corrected image from the preprocessing section 12 but also correction characteristic information 23 containing image characteristics regarding the correction (contrast enhancement). This attempts to reduce an influence of noises enhanced by the contrast enhancement.
