  • Publication number: 20230126046
    Abstract: From an input image, a candidate area in which an object exists is acquired. Furthermore, a confidence score indicating a possibility that the object exists and a class probability are acquired. An overlap ratio between candidate areas is calculated for each combination of two arbitrary detection results, and a combination of detection results with an overlap ratio equal to or larger than a threshold value is output as an overlap-detected group. A candidate area used as a representative area is determined from detection results included in the overlap-detected group based on a confidence score. Each class index is calculated based on the overlap ratio with respect to the representative area, and a class with the highest class index is determined as the class of the representative area.

  • Patent number: 9998631
    Abstract: An information processing method includes calculating at least one difference value between a pixel value of a target pixel in an input image obtained by capturing a document image and a pixel value of a corresponding pixel in a shade component image at coordinates identical to those of the target pixel. The shade component image represents shade components of the input image. The shade components depend on an image capture environment. The method further includes correcting the pixel value of the target pixel in the input image based on a correction rate to correct a shade component in the target pixel. The correction rate depends on at least one difference value associated with the target pixel in the input image.
