Processing an image for Iphone fax App -

i'm looking code cleans document picture, meaning takes out shadows , other noises , turns simple black & white image (black-the writing, white-the background).

maybe simple pixel algorithm helpful such as: dividing image rectangles, each defining frequent scale background , and darker pixels actual writing lines.

any help highly appreciated.

the problem code not distinct between letter , shadow. every dark pixel black regardless of context.

the required outcome should filter out noises such shadows clear black & white image.
