    摘要: A method for embedding coded information in a coupon with a face value denomination includes encoding that face value denomination value as a plurality of data carrying dot pair patterns where each dot is too small to be visually noticeable. For each page of a document to be rendered, the method includes determining whether the border area is blank. If found not blank the border area is cleared. Each of the plurality of data carrying dot patterns is embedded in the blank border area of the document page. The document page with the embedded data carrying dot patterns is then rendered, where each data carrying dot is too small to be visually noticeable.

    摘要: A text-like data representation technique and a text-like data representation apparatus are disclosed that may: acquire image data from a scanned image; segment text regions from the image data; further extract each connected component in the text regions; form clusters based on the connected components; group each connected component in the text regions into one of the clusters with similar or identical characters; generate a high-resolution representative for each cluster; generate a vector representation for each high-resolution representative; and code the text as text data by associating each connected component with its vectorized high-resolution representative, and location in the document.

    摘要: Systems and methods are described that facilitate dominant point detection for text in a scanned document. The dominant points are classified as “major” (e.g., structural) and “minor” (e.g., serif). A set of rules or parameters for each character is determined off-line. During the text vectorization, OCR is performed and the rules (parameters) associated with the recognized character are selected. Both major and minor dominant points are detected as a maximization process with the parameter set. For minor dominant points, additional processes are optionally employed.

    摘要: A method of color image processing for quantizing output includes obtaining an input for an object pixel which is represented by a vector in a first color space. A modified input equal to the input plus a sum of errors from other pixels in a neighborhood of the object pixel is generated. For each color component in the first color space, where corresponding color components of the modified input are located with respect to a preset range is determined. If the modified input's color component is greater than the preset range, then that color component for an output is determined to be on; if less than the preset range, then that color component for the output is determine to be off; and, if within the preset range, then that color component for the output is determined to be unknown. A transformed modified input is mapped to a perceptual color space when any color component of the output is unknown. Colors consistent with color components of the output that have already been determined are also mapped to the perceptual color space. The color in the perceptual color space that lies closest to the transformed modified input is chosen. An output in the first color space having color components on and off is generated consistent with the determinations and/or choices made. Error for the object pixel is then calculated as the difference between the output and the modified input.
