A method and apparatus for differentiating and extracting text and line graphics in an image. The method provides for the use of morphological operations, preferably at reduced scale, to eliminate vertical rules and lines from an image followed by the elimination of horizontal rules and lines, remaining text regions are then solidified to produce a separation mask. The mask is used in conjunction with the original image to produce separate text and graphics images.
