Abstract

A first aspect of the of the present invention is a system and method for classifying an input document based a segmentation tag statistics. The method includes receiving first pass segmentation tags for a plurality of pixels within a block of image data; determining an image type for the block of image data using statistics compiled from the first pass segmentation tags; and generating rendering tags for pixels within the block of image data as function of second pass segmentation tags and the image type. Beneficially, the image type identified for the block of image data is used to optimize the rendering process.
