ABSTRACT:
The present invention is a method and apparatus for automatically detecting the characteristics of a document object placed on the platen of a digital copier or similar scanning system. The invention accomplishes the detection by processing a digitized image in a highly efficient manner using binary moments, and using the moments characterizes the shape of a boundary about the object. Once determined, the shape of the object may be employed to further process the image to automatically crop, derotate, and register the image at a predefined location in an output image suitable for rendering on a document substrate.
