Abstract: An image evaluation apparatus includes a pixel extraction unit, an intra-pair difference calculation unit, an inter-pair difference calculation unit and an evaluation unit. The pixel extraction unit extracts, from an input image, a pixel region including a pair of block-boundary pixels in a boundary position of coding blocks and a pair of non-block-boundary pixels in a position other than the boundary position. The intra-pair difference calculation unit calculates a difference between the extracted pair of block-boundary pixels as a first difference, and a difference between the extracted pair of non-block-boundary pixels as a second difference. The inter-pair difference calculation unit calculates a difference between the first difference and the second difference as an amount of block distortion of the extracted pixel region. The evaluation unit evaluates an amount of block distortion of the input image based on the calculated amount of block distortion of the extracted pixel region.
Abstract: A system and method are provided by which a user, at a client workstation, can efficiently, simply and effectively manipulate, and specifically crop, a high resolution image that has been scanned and/or otherwise stored in a server with which the client worksation is in web-based communication. The disclosed system and method reduce and/or eliminate the need to transfer a file containing a full high resolution image from the server to the client workstation across a web-based data transfer network. A cropping request may be generated by a user via a client workstation and only that request may be transferred to, and implemented through, the server, eliminating significant data transfer requirements regarding the transfer of the extremely large files associated with high resolution images required of conventional cropping methods. An addition advantage is reduction and/or elimination of a need for sophisticated image display and processing software to reside within each client workstation.

Abstract: An extensible markup language document processing engine performs arbitrary processing on extensible markup language documents. The processing sequence of the extensible markup language document processing engine is not fixed, but rather can depend upon the information submitted with the job and upon determinations and analysis during the actual job processing. The extensible markup language document processing engine can also segment the document processing so that different fragments of the document are handled differently, thereby providing parallel processing capabilities. Moreover, the extensible markup language document processing engine can segment the document processing so that different fragments of the document are handled differently so that not all processing is blocked when a fragment requires a slow action, such as retrieval of information from the web.
Abstract: An image processing apparatus performs color conversion processing on an input image. The image processing apparatus includes a block pallet conversion unit, a first color converting unit and a restoration unit. The block pallet conversion unit converts the input image in units of blocks into (i) pallet color information including pallet colors number of which is less than pixels included in one of the blocks and (ii) selection information used to select one of the pallet colors for each pixel. The first color converting unit performs color conversion on the pallet color information obtained by the block pallet conversion unit. The restoration unit selects for each pixel, based on the selection information, one of the pallet colors of the pallet color information, which is color-converted by the first color converting unit, to restores an image.

Abstract: The bichromal element spinner apparatus provides the forming of substantially spherical bichromal elements from pigmented molten, but hardenable material compounds which are delivered centrally to a spinning webbed disk through opposite ends of hollow shaft that also spins with the disk. The molten materials are injected into cavities formed between the shaft and the web portions of the disk such that the molten materials are spun outwardly on the opposite surfaces of the disk towards the tip of the disk, where the hardenable materials adhere to each other without mixing, thereby spinning off to bichromal elements. Shrouds attached to the shaft and having no intervening support members over the spinning disk provide quiescent air mass between the disk and the shrouds so as to yield bichromal elements with substantial hemispherical integrity.
