Abstract

The present invention relates to a manuscript image processing system and method, which firstly utilizes a quad tree to recursively partition an image into a plurality of rectangular areas, and implements the image processing method of the present invention to correct a poor image quality of a manuscript on a whiteboard or a document taken by a digital camera under a bad image-taking condition. The image processing method of the present invention could perform image enhancement in accordance with a readability requirement of a manuscript image, so as to restore a clear and even background color of the manuscript image, and to enhance strokes of character contents to sharpen its handwriting. The present invention is not only good at enhancing the manuscript image with a white background and black handwriting, but also good at enhancing documents with a variety of foreground colors and background colors by converting color spaces before and after the image enhancement.
