Image processing system with image cropping and skew correction

Abstract

Abstract A system and method is described for automatically determining in a scanned document image 500 the presence of unwanted extraneous information caused by an extraneous device and scanner background information 504. Once the presence of this information is determined, the system and method of the present invention can compute, for instance, skew and crop statistics. From this, the image 500 can be automatically deskewed and cropped 322 appropriately without the background and extraneous information 504. The system and method accomplishes this by first determining the presence of unwanted extraneous and background information 504 and then appropriately processing the document image 500. The extraneous information 504 is ignored during deskew and crop computations. Also, the scanner background and the extraneous information 504 are prevented from being included in the final digital representation of the image 600.
