Title: Image processing system with automatic image cropping and skew correction

Abstract: A system and method is described for automatically determining in a scanneddocument image the presence of unwanted extraneous information caused byan extraneous device and scanner background information. Once the presenceof this information is determined, the system and method of the presentinvention can compute, for instance, skew and crop statistics. From this,the image can be automatically deskewed and cropped appropriately withoutthe background and extraneous information. The system and methodaccomplishes this by first determining the presence of unwanted extraneousand background information and then appropriately processing the documentimage. The extraneous information is ignored during deskew and cropcomputations. Also, the scanner background and the extraneous informationare prevented from being included in the final digital representation ofthe image.
