  • Image processing device, image processing method, and non-transitory recording medium
    Patent number: 10445854
    Abstract: An image processing device includes a label memory to store a first label assigned to a pixel in a previous line of a processing target image subjected to an assignment process prior to the assignment process on a processing target line of the processing target image, a label area memory to store identification information identifying a label area including pixels assigned with an identical label, and circuitry to, if at least one target pixel in the processing target line is an effective pixel, perform the assignment process on the target pixel based on at least one label that includes the first label and is assigned to at least one peripheral pixel peripheral to the target pixel, and to perform an updating process of updating the identification information based on a position of the target pixel and the label assigned to the target pixel.
