Abstract:
Image data is divided into blocks and a histogram of a color appearing in a target block is formed. A target color region is decided as significant, if the area of that region is larger than a threshold, or if that area is smaller than the threshold and if that region is located at a boundary of the target block and attribute information for the pixel at the boundary in that region indicates a preset attribute. If that region is not decided as significant, to integrate that region to a region of another color which contacts that region, the color of the pixel in that region is substituted by the other color. If that region is decided as significant and if the chrominance difference between that region and the region decided as significant in another block which contacts the target block is smaller than another threshold, these regions are integrated.
Abstract:
In order to implement color-reduction processing more suitable, an image processing apparatus includes: a reference pixel determination unit configured to determine a reference pixel by scanning first image data; a color space division unit configured to set a plurality of regions in a hue circle and a plurality of luminance levels, and to determine a plurality of bins; a frequency distribution generation unit configured to generate a frequency distribution; a determination unit configured to select N bins based on the generated frequency distribution and to determine N types of pixel values respectively corresponding to the selected N bins; and a substitution unit configured to substitute each of pixels included in the first image data using the determined N types of pixel values.
Abstract:
Character code data and vector drawing data are both listed and provided in a re-editable manner. Electronic data is generated in which information obtained by vectorizing character areas in an image and information obtained by recognizing characters in the image are stored in respective storage locations. As for the electronic data generated in this manner, because character code data and vector drawing data generated from the input image are both presented by a display and edit program, a user can immediately utilize the both data.
Abstract:
An information processing apparatus includes an area display unit configured to display a metadata area including metadata values arrayed for each metadata item and unique areas defined for respective metadata values, an icon display unit configured to display an icon associated with main body data and enabling a user to add the metadata, and an adding unit operable if the displayed icon is moved to a position on the metadata area and configured to add information defining a unique area to which the position of the moved icon belongs, as metadata, to main body data associated with the icon.
Abstract:
An image processing apparatus includes a character recognition unit configured to perform character recognition of a character region where characters exist in an image to generate character code, a detection unit configured to detect a region of the image where a feature change in the image is small, and a placement unit configured to place data obtained from the character code in the detected region.
Abstract:
An image in which at least one color component among a plurality of color components in an input color image has a resolution lower than that of the other color components is held as a base image. A rectangular region that includes an object image is extracted, a region of the object image and a region of a background image are specified in the rectangular region, and fill-up processing of the specified object image is executed in the base image. Fill-up processing executed at a boundary between the object image and the base image differs from fill-up processing executed at a boundary between the object image and the background image.

Abstract:
An image processing apparatus comprises a division unit configured to divide an input image into a plurality of tiles of a predetermined size; a resolution conversion unit configured to convert the input image into a low-resolution image; and a determination unit configured to determine an attribute of a tile of interest from a pixel feature in the tile of interest, the tile of interest being included in the plurality of tiles obtained by the division unit dividing the input image; a generation unit configured to generate a histogram for pixels in a low-resolution tile that is obtained by converting an image of the same region as the tile of interest into a low-resolution image, the histogram indicating a relationship between each color of pixels and the number of pixels of that color.
Abstract:
An image processing apparatus includes a region analysis unit configured to generate a quantized region by integrating regions that are included in an input multivalued image and have similar colors and to determine an attribute of a connected component included in the generated quantized region, and a character portion filling unit configured to determine a color used for filling a connected component that has been determined by the region analysis unit to have a character attribute and to execute processing for filling the connected component that has been determined to have the character attribute. In the image processing apparatus, the character portion filling unit is configured to change a method for determining the color used for filling based on the quantized region existing adjacent to the connected component determined to have the character attribute.
Abstract:
A method is provided that enables verification of whether a component of original image data has been altered at the location at which the component is to be reused without newly generating a signature. More specifically, the method includes inputting first document data including a plurality of components and signature information corresponding to the components, selecting at least one component from among the components, and extracting signature information corresponding to the at least one selected component. The method further includes storing the at least one selected component and the signature information corresponding to the at least one selected component in a memory, and generating second document data by pasting the at least one stored component and the stored signature information into a document selected as a paste location.
