  • 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.
