  • Patent number: 8218814
    Abstract: An image processing apparatus such as a monitor system for executing image processing to present a suspicious object effectively. An object detecting unit detects an object contained in an image, an associating unit associates a plurality of objects detected with the object detecting unit, with each other, and an evaluating unit evaluates (e.g., evaluation as being suspicious) an object detected by the object detecting unit, and an association evaluating unit evaluates another object associated by the associating unit with the object evaluated by the evaluating unit, in accordance with the evaluation made by the evaluating unit.

  • Patent number: 8189049
    Abstract: Binarization is performed using a threshold image obtained by multiplying a variation in each pixel value of an input image with a coefficient. Although the variation is time-averaged based on an update coefficient for each pixel, the update coefficient is switched depending on whether or not a relevant pixel belongs to the object. Subsequently, from the binary image, an initial detection zone is formed and a spatial filtering process is performed thereto. The spatial filtering process includes at least one of skeleton analysis processing, object mask processing, morphology processing, and section analysis processing. For a tracking zone, the temporal positional change thereof is tracked, and the noise is reduced. Some of the tracking zones are removed, and the remaining zones are integrated into a cluster, and furthermore the cluster selection is performed based on the dimensions in real space.

  • Publication number: 20090040238
    Abstract: A program is to be executed by a computer having an image display apparatus. The program, when executed, causes the computer to perform the functions of displaying an initial image on the display apparatus; receiving a zoom-in boundary designated on the displayed initial image, the part of the displayed initial image surrounded by the zoom-in boundary being a target image to be enlarged; detecting a size of the zoom-in boundary; comparing the detected size of the zoom-in boundary with a reference size; if the detected size of the zoom-in boundary is smaller than the reference size, setting a middle boundary that defines a redefined image on the initial image, and enlarging the redefined image to display the enlarged redefined image on the display apparatus. The redefined image includes the entire part of the target image and a part of the initial image outside of the zoom-in boundary.

  • Patent number: 5308772
    Abstract: A hematological specimen for classifying and counting leukocytes with a flow cytometer is prepared. A sample to be assayed is prepared by eliminating influences of erythrocytes from a hematological sample without changing leukocytes morphologically; adjusting the pH value to a level suitable for staining; and staining the leukocytes with at least two dyes including Astrazon Yellow 3G capable of specifically staining at least basophils and immature granulocytes and Neutral Red capable of specifically staining at least eosinophils. Thus leukocytes contained in the hematological sample can be classified at least three or six groups including immature granulocytes by measuring a single specimen with a flow cytometer.
