    摘要: Provided is a method for the automatic determination of a region of interest in an image, comprising the steps of: segmenting the image into a plurality of smaller regions, each region extending over a plurality of pixels; performing an analysis on each of said regions to characterize an aspect of the region relating to its level of importance in communicating information to a viewer; grouping adjacent regions having similar aspect characteristics; and identifying at least one group as a region of interest. Also provided is a method employing the steps above for use in an automated document composition process, where overlaid content is not placed over regions of interest that are identified.

    摘要: A system/method for generating one or more new hardcopy prints from an electronic file comprising original digital image data, wherein the new hardcopy print(s) match a legacy hardcopy previously generated from the original digital image data of the electronic file, even when the legacy hardcopy was printed from an “enhanced” or “tuned” version of the original image data. The original image data and scanner data derived by scanning the legacy hardcopy are used to identify corresponding areas of constant color in the original data and the legacy hardcopy. The corresponding color areas are represented in a colorimetric color space and the original data color values are adjusted to match the legacy hardcopy color values. The adjusted data are used to print a new hardcopy. The calorimetric color space conversion is completed using a plurality of different printing device assumptions, and the printing device assumption resulting in the smallest starting color difference between the original color values and legacy hardcopy color areas is used for the color matching process.

    摘要: An artifact removal and quality assurance method and system for digital images, wherein a document comprising at least one printed page is scanned or the original image data are otherwise input. The input digital image data are segmented into components as to content type. The components are classified as either information or noise components. An information component image defined by the information components and a noise component image defined by the noise components are generated and displayed to the user. The user inputs quality assurance input data to indicate zero or more improperly classified components and any improperly classified component is reclassified. The component images are then regenerated and displayed to account for the reclassified component(s). The reclassified component is moved as a unit in real time as viewed by the user from an original location in one of the component images to a corresponding location in the other of the component images. Both component images are saved or otherwise output as desired.

    摘要: The present invention is a method and apparatus for automatic image segmentation using template matching filters. The invention generally segments differing binary textures or structures within an input image by passing one or more structures while removing other structures. More particularly, the method and apparatus segment a stored binary image using a template matching filter that is designed to pass therethrough, for example, text regions while removing halftone regions.

    摘要: An error diffusion processor for preparing a document image for printing. Shadows and highlights regions stress error diffusion processes, because accumulated error cannot be easily compensated for in these regions. Edge enhancement emphasizes the problem by locally increasing error in order to maintain spatial detail of the image. The arrangement described puts an additional term into the error calculation that is a function of local intensity, with substantial value only in shadow and highlight regions to correct for edge enhancement artifacts.

    摘要: An apparatus, method and system optimizes Huffman codes within the Huffman tables without requiring buffering an entire uncompressed original image. Compression of a whole image is performed prior to storage in a buffer. Therefore, the necessary buffer size for performing computation of symbol frequencies in order to optimize Huffman codes is reduced. Default Huffman codes are used to pre-compress the image for storage in the buffer. Simultaneously, the input symbol frequency is determined to produce optimized Huffman codes. The optimized Huffman codes are used to optimally re-encode the encoded image data to reduce the space of the re-encoded data. The optimally encoded image data can then be stored and/or transmitted.

    摘要: The present invention describes a method for automatic cropping of images containing regions where intensity levels are uniform and other regions where intensity levels vary considerably. An image to be automatically cropped is scaled down to a grid and divided into non-overlapping blocks. The mean and variance of intensity levels are calculated for each block. Based on the distribution of variances in the blocks, a threshold is selected for the variance. All blocks with a variance higher than this threshold variance are selected as regions of interest. The regions of interest are then cropped to a bounding rectangle.
