Abstract:

Provided are a method, system, and an article of manufacture for registration calibration of a printer. An application prints reticle patterns on a printed page. An imaging device creates a digital image of the printed reticle patterns. If color registration on the printer is improper, the digital image exhibits interference patterns. The application compares the interference patterns to the reticle patterns, and based on the results of the comparison adjusts the color registration of the printer.

International Classification:

US Classification:

708400, 708402

Abstract:

Fast transforms that use multiple scaled terms is disclosed. The discrete transforms are split into sub-transforms that are independently calculated using multiple scaling terms on the transform constants. The effect of the scaling for the transform coefficients may optionally be handled by appropriately scaling the quantization values or any comparison values. Further, optimal representations of the scaled terms for binary arithmetic are found. The resulting calculations result in fast transform calculations, decreased software execution times and reduced hardware requirements for many linear transforms used in signal and image processing application, e. g. , the DCT, DFT and DWT.

International Classification:

US Classification:

717149, 717159, 708513, 712 22

Abstract:

A compiler for data processing outputs lower-level code for packing multiple signed data elements per register into a processor's registers using the rules set forth herein, and when executed, the code simultaneously operates on the elements in a register in a single cycle using the same operand. The elements can be independent of each other as defined by compiler directives, and the sizes of the elements in a register can differ from each other. Moreover, a relatively large element can be split across multiple registers. In an exemplary application, a data stream representing two images can be simultaneously processed using the same number of registers as have been required to process a single image. Or, a single image can be processed approaching N-times faster, where N is the number of elements per register. In any case, the present invention results in a significant increase in processing efficiency.

International Classification:

H04N 1/405

US Classification:

358 313, 358 314, 358 316, 358535

Abstract:

Apparatus and method for flexible digital halftoning are provided in which novel pattern choices are allowed by not restricting the basic halftone patterns to grow sequentially. Rather, positions in a threshold array allow multiple transitions between on (i. e. , printed with toner/ink) and off (not printed) as a function of the input value at the corresponding position. In one embodiment, multiple threshold matrices are employed and the output decision is a vote (e. g. , exclusive OR) of the outputs of the individual threshold matrices. In another embodiment, each position contains an arbitrary bit vector to express the output for each input. This flexibility in growing basic halftone patterns allows the number of densities output to be larger than n+1 (where “n” is the number of dots within a basic halftone cell).

358 306, 358 313, 358 314, 347101

Abstract:

A method, apparatus and article of manufacture for modifying printing based upon direct on-the-fly media characteristic parameters is disclosed. The present invention on-the-fly directly measures a media characteristic parameter and performs real-time print modification in response thereto. The measured characteristic parameters include paper texture and composition, as well as adhesion and penetration of print. The modification of print in response to these measured parameters may allow a customer to maintain observed print quality with lower-cost materials. Adjustments may include the addition of coating, hot rolling, or adjustment of toner concentration. Measured parameters may include mottle, paper texture, and bleed through.

Abstract:

A content framework system and method. The content framework system comprises a content infrastructure, a content flow management system, and a content association system. The content infrastructure comprises content management systems. Each of the content management systems comprises content. The content flow management system comprises an acquisition tool comprising an agent tool. The content flow management system controls a flow of each of the content within and between each of the content management systems. The acquisition tool provides an interface between the content flow management system and the content infrastructure. The content association system generates a first set of associations metadata comprising a first set of links for linking the content management systems together. The agent tool monitors the content from each of the content management systems and adding to a registry, a description of the content from each of the content management systems based on the monitoring.

US Classification:

Abstract:

The invention provides a method, data compression system, apparatus, and article of manufacture which reduce the error in transform equations in which constants are replaced by approximations. According to the invention transform constants are replaced with approximations which are a function of an integer and a floating point value. The transform equation is then performed with the integers in place of the constants. The floating point value may be applied either to the result of the equation or to the data to be processed by the transform equation before the equation is performed. Further the floating point value may be applied using a fixed precision version of the value or a fixed precision value into which the floating point value has been factored.
