ABSTRACT:
An image markup detection device and method identifies and extracts markup lines and regions marked automatically or interactively by a user with an ordinary pen or pencil. Only morphological image processing operations on a scanned source image are used, resulting in the extrapolation of markup lines and marked region. The markup lines are either extracted from the image, or the background information of the image (e.g., text) is removed, leaving only the markup lines. The marked region can then be printed, transferred or otherwise processed.
