Abstract: A method is described for electronically storing images of previously copied documents and recalling them for reprinting later. When a user uses a copier to make a physical copy of a physical document, the document image is stored by the copier, and certain document management information is captured and stored in a document management database to facilitate later recall and reprint of the document images. A document management section, which resides either on the copier or on a server connected to the copier by a network, performs document management functions that allow a user to select a previously copied and stored document for reprinting.

Abstract: A method is described for automatically predicting user-preferred printer settings based on past user behavior. A driver service module maintains an application/driver/user (ADU) settings database that stores printer settings associated with the application that initiated the print job, the printer driver and versions thereof, and (in a multiple user environment) the user's identity. Each time a print job is initiated, the driver service module analyzes the ADU database to determine a predicted user-preferred setting. The user may manually change the setting and confirm it, and the driver service module stores the user confirmed setting in the ADU database for future use. The method can transfer user-preferred settings associated with one application or one printer driver (or a version thereof) to another application or another printer driver (or another version thereof). It further allows user preference information to be accessed or transferred over a network.

Abstract: A document authentication method determines the authenticity of a target hardcopy document, which purports to be a true copy of an original hardcopy document. The method compares a binarized image of the target document with a binarized image of the original document which has been stored in a storage device. The image of the original document is generated by binarizing a scanned grayscale image of the original document. Halftone and non-halftone text areas in the grayscale image area separated, and the two types of text are separately binarized. The non-halftone text areas are then down-sampled. During authenticating, a scanned grayscale image of the target document is binarized by separating halftone and non-halftone text areas and binarizing them separately, and then down-sampling the non-halftone text areas. The binarized images of the target document and the original document are compared to determine the authenticity of the target document.

Abstract: A document authentication method employs Krawtchouk decomposition to analyze and compare document images. When printing an original document, the original document image is segmented into image patches, which preferably correspond to individual symbols of the document. Krawtchouk decomposition is applied to each image patch. The image patches are classified into image patch classes using their Krawtchouk coefficients. The locations of all image patches belonging to each class are obtained and stored along with the Krawtchouk coefficients for each class. When authenticating a target document, the same segmentation, Krawtchouk decomposition and classification steps are applied to the target document image, and the locations of all image patches belonging to each class are obtained. The image patch classes and the locations of image patches belonging to each class for the original and target document image are compared to detect alterations present in the target document.

Abstract: A method implemented in a fax machine for analyzing a received fax to determine whether it is an auto-reply fax. Auto-reply faxes are handled differently from other faxes to avoid unnecessary printing. The analysis method includes: determining whether the sender of the received fax is the same as the receiver of a fax sent by the fax machine within a predefined time period in the past; determining whether the received fax contains only one or two pages; extracting text from the image of the received fax using OCR; and detecting the presents of certain keywords in the extracted text which indicate an auto-reply or received status. These determination and detection results are combined to determine whether the received fax is an auto-reply. Auto-reply faxes may be saved but not automatically printed, or forwarded to an email box of the sender of the original fax, etc.

Abstract: A method is described to obtain a binary image from the print-and-scan process to best match the known original. A point-spread function (PSF) of the PAS process is first obtained from its knife-edge responses, and deblurring is carried out on the scanned images using deconvolution. After image deskewing and preliminary registration, a supervised adaptive thresholding procedure is utilized to binarize the scanned image such that a measure of difference (e.g. the Euclidean distance) between the original and binarized images is minimized. The supervised adaptive thresholding procedure divides the scanned images into many rectangular sub-images. Otsu's method is used to find a starting threshold for each scanned sub-image. An optimal threshold is found around the Otsu's threshold via iterative search to minimize the measure of difference between the original sub-image and scanned sub-image. The sub-images are binarized using the optimal threshold. This method may be used in document authentication.

Abstract translation: 描述了一种从打印和扫描过程获得二进制图像以最佳地匹配已知原始图像的方法。 PAS过程的点扩散函数（PSF）首先从其刀刃响应获得，并且使用去卷积在扫描图像上进行去模糊。 在图像去歪斜和初步注册之后，利用监督的自适应阈值处理来对扫描的图像进行二值化，使原始和二值化图像之间的差异度量（例如，欧氏距离）最小化。 监督的自适应阈值程序将扫描的图像分成许多矩形子图像。 Otsu的方法用于找到每个扫描的子图像的起始阈值。 通过迭代搜索在Otsu阈值周围找到最佳阈值，以最小化原始子图像和扫描子图像之间差异的度量。 子图像使用最优阈值进行二值化。 该方法可用于文档认证。
