ABSTRACT:
An apparatus, method, system, computer program and product, each capable of extracting a background area of a document image. The background area of the document image may be extracted by repeating recursively the acts of: extracting a set of white rectangles from a processed area of the document image; dividing the processed area into a plurality of segments using the set of white rectangles as a separator; storing the plurality of segments; and reading the plurality of segments in a predetermined order as a processed area.
