  • Patent number: 8155396
    Abstract: An apparatus detects a predetermined number of facial images from detection target images. An inclination order setting means utilizes the correlative relationships among correlative data obtained by a correlative data obtaining means and the inclinations of faces that appear in input images, to determine the relative value of the probability that faces of a predetermined inclination will appear in the input images. The inclination order setting means sets the order of inclinations of faces to be detected such that faces are detected in order of inclinations according to the relative values of the probabilities, based on the correlative data that they will appear. A face detecting means detects faces within the input images while varying the inclinations of faces to be detected according to the set order.

  • Publication number: 20120076267
    Abstract: Disclosed is a technique for correcting a pixel defect in the capture of two radiological images with parallax therebetween. Radiation beam is directly radiated to a radiation detector 15 in two radiographing directions, without passing through a subject, thereby acquiring two defect detecting radiological images. A pixel defect in each of the two defect detecting radiological images is detected in advance. A pixel position where the pixel defect occurs is stored in advance so as to be associated with each radiographing direction. Then, radiation beam is radiated to the subject from the two radiographing directions to acquire two radiological images for diagnosis. A target pixel which is disposed at the stored pixel position where the pixel defect occurs in each of the two radiological images for diagnosis is corrected.

  • Publication number: 20120051502
    Abstract: In a mammography system including a face guard, it is possible to prevent a human subject whose head is in close contact with the face guard from losing her posture and being in an unstable state. In a mammography system which includes a shield member for preventing radiation from being irradiated onto the face of the human subject, a radiation source which irradiates radiation is moved, such that, when radiation in two radiographing directions is irradiated from two focal positions distant from the chest wall of the human subject in a forward direction, the shield member is configured to be fixed at a predetermined position in the forward direction without being interlocking with the movement of the radiation source.

  • Patent number: 8078010
    Abstract: To acquire a high-resolution frame from a plurality of frames sampled from a video image, it is necessary to obtain a high-resolution frame with reduced picture quality degradation regardless of motion of a subject included in the frame. Because of this, between a plurality of contiguous frames FrN and FrN+1, there is estimated a correspondent relationship. Based on the correspondent relationship, the frames FrN+1 and FrN are interposed to obtain first and second interpolated frames FrH1 and FrH2. Based on the correspondent relationship, the coordinates of the frame FrN+1 are transformed, and from a correlation value with the frame FrN, there is obtained a weighting coefficient ?(x°, y°) that makes the weight of the first interpolated frame FrH1 greater as a correlation becomes greater. With the weighting coefficient, the first and second interpolated frames are weighted and added to acquire a synthesized frame FrG.

  • Patent number: 8068645
    Abstract: In order to cause a structure such as a human face in an image to become unidentifiable while causing the image to have a natural finish, a parameter acquisition unit obtains weighting parameters representing a characteristic of an individual in a face region in the image by fitting to the face region detected by a face detection unit a mathematical model generated by a method of AAM using a plurality of sample images representing human faces. A reconstruction unit changes the weighting parameters to become smaller, and reconstructs the face region by using the parameters having been changed.

  • Publication number: 20110254981
    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.
