摘要： Customer support systems and associated methods are disclosed. A customer wishes to inquire about a particular document individualized for the customer and sends a support request to a customer support system using a client device. The support request includes identification information of the customer and image information based on an image captured by the customer from a copy of the particular document. The customer support system is operable to receive the support request and to select a subset of documents for the customer from a plurality of documents for a plurality of documents based on the identification information. The customer support system is further operable to identify the document from the subset of documents based on the image information, and to initiate a response to the support request using information from the document.

摘要： A printing system is disclosed. The printing system includes an image processor to rasterize a received print job and to perform a halftone by comparing a first threshold value from a threshold matrix to a first image component sample, comparing the first threshold value to a first number of sequential image component samples neighboring the first sample if the first threshold value is less than the first sample and comparing the first threshold value to a second number of sequential image component samples neighboring the first sample if the first threshold value is greater than or equal to the first sample.

摘要： The scaling down of data is provided. At least two blocks of transformed data samples representing at least two blocks of original data samples are received. One of at least two tables of constants is selected wherein each table of constants is capable of reducing the number of transformed data samples by a different factor. The constants taken from the selected table are applied to the at least two blocks of transformed data samples to produce one block of transformed data samples representing one block of final data samples. The data is processed one dimension at a time by multiplying the data in one dimension with selected constants taken from previously developed tables corresponding to the desired scale down factor. Scaling down by different factors in each dimension as well as scaling down in one dimension and scaling up in the other dimension may be achieved. In addition, the de-quantization of the quantized transform coefficients may be accomplished by pre-multiplication of the selected constants when the quantization values are known. In a similar way the re-quantization may be accomplished by a pre-division of the selected constants. Both de-quantization and re-quantization may be combined when the input quantized transform coefficients and output quantized transform coefficients are desired.

摘要： A method, system, and program for decoding cached compressed data. Compressed data is received and decoded. An error is detected while decoding a first location in the compressed data. A reentry data set is accessed having a pointer to a second location in the compressed data following the first location and decoding information that enables decoding to start from the second location. The second location in the compressed data is accessed and the decoding information in the accessed reentry data set is used to continue decoding the compressed data from the second location.

摘要： Systems, methods and program products for recording a document's background data during front-end generation of the document, and inserting a background data identifier on the document. In addition, the invention provides for use of the background data for document processing. For example, the invention provides for removal of the background data from scanner image data of the document to create a foreground image. The foreground image can be used to conduct processing relative to the document such as archiving, fraud detection and other processing. Background data recordation and removal during back-end processing results in improved archive accuracy, lowered storage size requirements, and reduced transmission costs. In addition, background data recordation allows referencing of a single background by a large number of documents.

摘要： We present a communication system which enables two or more parties to secretly communicate through an existing digital channel which has a primary function other than this secret communication. A first party receives a series of cover data sets, hides a certain amount of auxiliary data in the cover data sets, and then relays these cover data sets containing hidden data to a second party, aware of the hidden data. This second party may then extract the hidden data and either restore it to its original state (the state it was in before the first party received it) and send it along to its original intended destination, or may just simply extract the hidden auxiliary data. There exist a plethora of techniques for hiding auxiliary data in cover data, and any of these can be used for the hiding phase of the system. For example, in a JPEG cover data set, a Huffman table may be modified in such a way as to have no impact on the observable nature of the image, and several such schemes are presented here. Since there are so many ways in which to exploit a particular cover data set for secret communication, it is necessary that the first and second parties have pre-established a set of rules by which they will communicate. There must be agreement on the hiding technique, cover data type and location of the hidden data within the cover.

摘要： An intermediate data format which is readily convertible to or from JPEG compliant data streams and to or from image data provides, in most circumstances, accelerated encoding and decoding in a degree sufficient to allow additional processing without necessitating increase of processor power even in relatively time-critical applications such as high-speed printers and image browsers. The format features flags which indicate if S>8 (indicating that extra bits are required to uniquely encode an orthogonal transform coefficient value) or runs of zero-valued orthogonal transform coefficients longer than sixteen are present in a block of data. The block of data can be tested for these conditions and flags set once per block or once per image. Extensive processing can thus be omitted if either or both of these conditions are not present, as will generally be the case.

摘要： A method, system, and data structure for the scaling up of data is provided. A block of transformed data samples is received wherein the transformed data samples represent original data samples. One of at least two tables of constants is selected wherein each table of constants is capable of increasing the number of data samples by a different factor. The constants taken from the selected table are applied to the block of transformed data samples to produce at least two blocks of transformed data samples representing at least two blocks of original data samples. The data is processed one dimension at a time by multiplying the data in one dimension with selected constants taken from previously developed tables corresponding to the desired scale up factor. Scaling up by different factors in each dimension as well as scaling down in one dimension and scaling up in the other dimension may be achieved. In addition, the de-quantization of the quantized transform coefficients may be accomplished by pre-multiplication of the scaling constants when the quantization values are known. In a similar way the re-quantization may be accomplished by a pre-divsion of the scaling constants. Both de-quantization and re-quantization may be combined when the input quantized transform coefficients and output quantized transform coefficients are desired.
