  • Publication number: 20220406082
    Abstract: In a scene where a pseudo character image is generated by performing deformation processing for a character image, a character image that impedes training is suppressed from being generated. Based on a condition relating to a parameter that is used for the deformation processing and associated with a first class, a parameter of the deformation processing is determined and the deformation processing is performed for a character image belonging to the first class using the determined parameter. Then, whether or not the deformed character image generated by the deformation processing is similar to a character image belonging to a class different from the first class is determined and in a case where similarity is determined, the condition associated with the first class is updated.

  • Publication number: 20220406083
    Abstract: A training image that simulates a character block entered by part of a character in another row is generated efficiently. A noise is added in the vicinity of an end portion of a character image so that a noise that seems to be caused by entering of part of a character in another row is reproduced for the character image representing a handwritten character.

  • Patent number: 11521365
    Abstract: An image processing system acquires a scanned image obtained by scanning an original, and extracts a character region that includes characters from within the scanned image. The image processing system performs conversion processing, for converting a font of a character included in the extracted character region from a first font to a second font, on the scanned image using a conversion model for which training has been performed in advance so as to convert characters of the first font in an inputted image into characters of the second font and output a converted image. Then, the image processing system executes OCR on the scanned image after the conversion processing.

  • Patent number: 11496635
    Abstract: An information processing system acquires, using a reading device, a read image from an original on which a handwritten character is written; acquires, based on the read image, a partial image that is a partial region of the read image and a binarized image that expresses the partial image by two tones; performs learning of a learning model based on learning data that uses the partial image as a correct answer image and the binarized image as an input image; acquires print data including a font character; generates conversion image data including a gradation character obtained by inputting the font character to the learning model; and causes an image forming device to form an image based on the generated conversion image data.

  • Patent number: 9041646
    Abstract: An information processing system determines a relationship between an observer and an observation target person based on personal information of the observer and personal information of the observation target person, and displays content information generated based on the determined relationship together with an image of the observation target person in a display area of a display unit.
