Abstract: The present invention is an intelligent scanning system for processing a digital input image to automatically characterize a plurality of objects therein. The system then employs the characterizations as the basis for rudimentary image editing operations so as to produce a digital document. In the digital document, the objects may be derotated, shifted, cropped or otherwise aligned in a predetermined fashion in accordance with a template. The scanning apparatus of the present invention not only enables the scanning of a plurality of objects, but does so in an intelligent manner so as to enable further processing and manipulation of the images associated with the objects to create an output document.

Abstract: A method of detecting halftones in the wavelet domain includes determining an energy value for the sub-bands in a wavelet decomposition. The calculated energy values are compared to a model of energy values that are expected when halftone data are not present. If the actual energy values do not conform to the model, halftone data are deemed to be present. In one embodiment, the model defines a pattern of decaying sub-band energy for each sub-band moving from a highest level of the wavelet decomposition to the lowest level of the decomposition. In another embodiment, the expected energy values in the model vary depending upon the bit-rate of compression of the wavelet-domain data.

Abstract: A method for coating an ink jet printhead with an ink-phobic coating includes applying the coating to an outer surface of the printhead and then drawing or forcing the coating through the apertures of the printhead, preferably with a vacuum. The method coats and renders ink-phobic not only the outer surface, but also the inside surfaces of the apertures. The ink-phobic coating may contain an amorphous fluoropolymer.

Abstract: A sheet feeder (14) for a print engine (10) includes a paper tray (30) which holds a stack of sheets (22) including a top sheet (20), and a pick-roller (42) which makes contact with the top sheet (20). The pick-roller (42) is rotatable about an axis. Also included is a driver (44), which upon forward energizing, rotationally drives the pick-roller (42) about the axis in a forward direction to advance the top sheet (20) to sheet advancing means (34) that pass the top sheet (20) along through the print engine (10). A drive controller (50) controls the driver (44). The drive controller (50) causes the pick-roller (42) to be released for free-wheeling after advancing the top sheet (20) to the sheet advancing means (34).

Abstract: Seamed belts, particularly puzzle-cut imageable seam intermediate transfer belts, and marking machines that use such belts, that have a beveled sides across the thickness of the belt. When the first and second ends are interlocked the bevel points are adjacent one another and a substantially V-shaped channel is formed. An adhesive is disposed in that channel. The V-shaped channel beneficially continuously extends along the puzzle-cut seam.

Abstract: This invention relates to a method and apparatus for implementing a trapping operation on a digital image during image processing. More specifically, the invention is directed to implementation of a trapping technique to prevent visual gaps or overlaps between colors on a poorly registered image that is produced by an imaging device, e.g. a color printer. The invention is most advantageously used in an imaging device that incorporates therein a split-level buffer.

Abstract: In a text recognition system that uses a stochastic finite state network to model a document image layout, the computational efficiency of text line decoding is improved. In a typical implementation, the dynamic programming operation that accomplishes decoding uses actual scores computed between two-dimensional (2D) bitmapped character template images and the (2D) bitmapped observed image. Scoring measures the degree of a match between a character template and the observed image. Computation of these actual scores is replaced with the simpler computation of column-based (i.e., one-dimensional) heuristic scores. Because the column-based heuristic scores can be shown to be a true upper bound on actual template-image scores, the heuristic scores are accurate enough to use in place of actual scoring during text line decoding.

Abstract: A Document Image Segmentation method is disclosed for matching a plurality of templates with a received image wherein the received image being bitmap data including at least a plurality of gray-scale pixel tiles that define the received image, the matching method having the steps of first receiving said image data so as to extract pixel tile information of said received image wherein said pixel tile information being of a predetermined matrix size; then matching loosely said pixel tile information with at least one of a plurality of templates so as to generate pixel-wise looseness interval values there between; and finally outputting an identifier associated with the matching template such that said identifier indicates a classification. The classification is preferably based on at least one of continuous tone pictorials, text, half tones, high/low frequency range; and line art graphic. Also, preferably the classification contains information about the image source.

Abstract: A method and system for unifying component metadata includes components, such as computers, laptops or flat panel display devices and software entities, connected together by one or more networks. A method includes a first component, such as a laptop device, obtaining intrinsic metadata associated with one or more other components, such as a computer and a flat panel display device. The first component combines intrinsic metadata received from each component with extrinsic metadata of the first component, and provides the combined metadata to the other components, although the first component may also utilize the combined metadata. The components are able to obtain a consistent, unified view of the combined metadata without needing any prior programming and without requiring the use of centralized servers.

Abstract: An electrostatic latent image developing dry toner and the like are provided, in which toner remaining after transfer can be recovered during developing with or without having a blade cleaning stage for promoting friction of an electrostatic latent image holding member. The electrostatic latent image developing toner contains toner particles containing a binder resin and a colorant and monodisperse resin particles having a volume mean diameter of 80 to 300 nm, a gel ratio of 60% or more by weight, and a standard deviation of D50×0.20 or less. A method of producing the above toner first mixes monodisperse resin particles, which have a volume mean diameter of 80 to 300 nm, a gel ratio of 60% or more by weight, and a standard deviation of D50×0.20 or less, with toner particles containing a binder resin and a colorant, and adds an inorganic compound having a diameter smaller than that of the resin particles with a shear lower than the first mixing.
