  • Patent number: 9271773
    Abstract: The present invention discloses an approximately ?-shaped improved bone plate structure, fixed on a bone of an animal for maintaining the relative positions of different portions of the bone. One of the other features of the present invention is that bone plate structure comprises at least one contouring portion for allowing the surgeons to intra-operatively adjusting the shape in accordance with the shape of the bone. Furthermore, the present invention may fit the bone with multi-axis, decreasing stress concentration, preventing the opening portion from being unsuitably covered and preventing the wound deformation from being pressed.

  • Patent number: 9066036
    Abstract: Disclosed is a method of generating an electronic document having an enclosed region with a fill color. The method receives a digital representation of a source document, the source document containing an enclosed region and at least one corresponding background region, the enclosed region overlapping at least a portion of the background region. A fill color is determined for the enclosed region from the digital representation as is a reference background color for the enclosed region from the corresponding background region of the digital representation. The method assigns a transparent fill color to the enclosed region based on a comparison of the determined fill color for the enclosed region with the reference background color and stores enclosed region with the transparent fill color to generate an electronic document.

  • Patent number: 8644602
    Abstract: A method (199) is disclosed for modifying colors of text extracted from an image of a document page to improve visual quality. The document image comprises text and image regions of various colors. The method divides (100) the document image into a plurality of connected components, the connected components comprising pixels of similar color that are closely spatially located, and selects from the image a plurality of the connected components that represent text. The plurality of text connected components are grouped to form a logical structure grouping of said page comprising one or more text blocks wherein each said text block represents a text line or paragraph. One or more logically consistent color sets are then formed (120, 699, 399, 499) for each text block based on the colors of the connected components in the text block. The logically consistent color sets represent all text of visually similar color of the corresponding text line or paragraph.

  • Patent number: 8532374
    Abstract: Disclosed is a method of classifying segmented contents of a scanned image of a document. The method comprise partitioning the scanned image into color segmented tiles at pixel level. The method then generates superpositioned segmented contents, each segmented content representing related color segments in at least one color segmented tile. Statistics are then calculated for each segmented content using pixel level statistics from each of the tile color segments included in segmented content, and then determines a classification for each segmented content based on the calculated statistics. The segmented content may be macroregions. The macroregions may form part of a multi-layered document representation of the document.

  • Patent number: 8503781
    Abstract: Methods (1200), apparatuses, and computer program for finding a region containing text in a color bitmap image comprising pixels are provided. Connected components (CCs) are generated (1200) from the color bitmap image by grouping substantially similarly colored and adjacent pixels. Independently of color, which of the connected components are text connected components are determined (1212) dependent upon attributes of the generated connected components. For each text CC) a value is assigned (1214) to each tile that comprises at least a portion of the text connected component. The value indicates the presence of text overlapping the tile. Each tile comprises pixels of the color bitmap image. The region containing text in the color bitmap image is determined (1216) dependent upon the assigned values of the tiles.

  • Patent number: 8472716
    Abstract: A method detects noise in a document image. The image includes pixels representing at least text and image data forming the document. The noise includes at least one of halftone, bleeding and texture noise. The method partitions the image into tiles, formed of pixels, determines a set of dominant colors for each tile, associates each pixel with one of the determined dominant colors, and then determines for each dominant color a fragmentation statistic, and applies a threshold to each statistic to detect the noise in the corresponding dominant color in the tile. Detected noise in the image is reduced by (a) merging colors with noise to one color without noise if the noise is halftone noise or texture noise; and (b) removing the colors with noise if the noise is bleeding noise. The pixels of the tile are then quantized to those remaining dominant colors of the set.

  • Patent number: 8411942
    Abstract: A Hybrid Compressor and method of compressing a tile of pixels within an image are disclosed. An Edge Processor of the Hybrid Compressor analyzes pixel runs of the tile and generates boundary data defining one or more regions comprising pixels of substantially identical color. A Palette Processor of the Hybrid Compressor generates data defining a color value for each region. An Image Processor of the Hybrid Compressor generates a representation of pixels not included in the one or more regions.

  • Patent number: 8351691
    Abstract: A method of text extraction in color compound documents is described. The method connects similarly colored pixels of an image of a color compound document into connected components (CCs); classifies each CC as either text or non-text; refines the text CC classification for each text CC using global color context statistics; groups text CCs into text blocks; recovers misclassified non-text CCs into a nearby text block; and removes extraneous CCs from each text block using local color context statistics to thereby provide the extracted text in the text blocks. Also described is a method of locating graphics objects in a color compound document image.

  • Patent number: 7991224
    Abstract: A method (100), an apparatus, and a computer program product for automatically producing a compact representation of a colour document are disclosed. In the method, a digital image of a colour-document page is segmented (110) into connected components in one-pass, block raster order. The digital image of the page is partitioned into foreground and background images using layout analysis (120) based on compact, connected-component statistics of the whole page. At least one portion of the background image where at least one portion of the foreground image obscures the background image is inpainting (520) in one-pass block raster order. The foreground and background images are combined (130) to form a compact document. A method, an apparatus, and a computer program product for segmenting a digital image comprising a plurality of pixels are also disclosed.
