  • Patent number: 10339418
    Abstract: A computation unit calculates luminance differences of individual pixel pairs in a feature area and calculates, based thereon, a local feature value formed from bit values respectively corresponding to the pixel pairs. Specifically, the computation unit calculates a specific luminance difference for a specific pixel pair corresponding to a specific bit value and then compares the result with a specified range including a zero point of luminance difference. Then a first value is assigned to the specific bit value when the specific luminance difference is greater than the upper bound of the specified range. A second value is assigned to the same when the specific luminance difference is smaller than the lower bound of the specified range. A predetermined one of the first and second values is assigned to the same when the specific luminance difference falls in the specified range.

  • Publication number: 20170293802
    Abstract: A memory stores area information indicating a pitcher area in which a pitcher is presumed to appear in an image that represents a pitching scene. A processor detects an edge pixel from a difference image that represents a difference between a first image at a first time and a second image at a second time that are included in a video, and identifies an edge area in which a plurality of edge pixels are aligned in a prescribed direction in the difference image. Then, the processor determines that the difference image represents the pitching scene on the basis of a size of the edge area included in the pitcher area indicated by the area information in the difference image and on the basis of a size of the edge area included in a prescribed area in the difference image.

  • Patent number: 9514382
    Abstract: A binarization processing unit generates a binary image by comparing the visual feature of each pixel of an input image with a predetermined binarization threshold and binarizing the value of each pixel of the input image based on the comparison result. The binarization processing unit performs this process while changing the binarization threshold, thereby generating a plurality of binary images. A contour detecting unit calculates the area of a closed region having an overlap between the plurality of binary images, and determines the binarization threshold to be used for detecting a boundary of the corresponding closed region as a contour of an object, based on the area change rate of the corresponding closed region caused by changing the binarization threshold.
