Abstract
In one embodiment, the invention discloses, a method for processing a document image. The method comprises segmenting the document image into a picture component and a non-picture component; compressing the non-picture component; and saving the uncompressed picture component and the compressed non-picture component in memory so that the document image may be recomposed to form a recomposed image based on the uncompressed picture component and the compressed non-picture component.
