Abstract
Disclosed are methods and multi-function devices for auto-correction of shadow effects in a scanned image. The method includes receiving a first image including a colored twin-page scanned document including at least one of a shadow region in a central part of the first image, at least one darker region caused at one or more borders of the first image, and distorted orientation with respect to a base of the first image; re-positioning the shadow region present in the central part to generate a re-positioned first binary image such that the shadow region becomes perpendicular to the base; detecting a shadow region in a central region of the re-positioned first binary image; removing the detected at least one shadow region from the re-positioned first binary image to generate a second image; and correcting a skewed orientation of each of a cropped left side and right side of the second image.
