Abstract:
Methods and systems for rendering an image. In an example embodiment, a step or operation can be implemented to pre-render white objects in an image with a background image set to a single complementary color. Such a single complimentary color assists in obtaining the textual content only from the complex background. A connected component analysis can be performed with respect to said image to identify elements in said images that should be rendered as objects composed of text and graphics. Tags are then assigned for final rendering of the image after performing said component analysis with respect to said image. Modification of tag values with respect to said images avoids unwanted artifacts such as, for example, bleed through, background closing, ghost effects, etc.
