  • Removing artifacts from document images
    Patent number: 9852498
    Abstract: Techniques for removing artifacts, such as shadows, from document images are described. A shadow map is generated for a digital image by first determining local background colors using clusters of local pixel intensities. Then, a global reference background color is selected from all pixel intensities of the digital image. Next, a per-pixel scaling factor is determined that maps the local background colors to the global reference background color, which applies localized adjustment to the digital image to remove local shadow.
    Type: Grant

    Assignee: ADOBE SYSTEMS INCORPORATED
