Abstract:
A software-controlled method for minimizing color toner use during printing of a color page by a color printer including (a) examining the image data for such a page to identify different pre-selected categories of page-contained image elements, (b) associating, with identified different-categories of such elements, specific, respective, pre-determined color-toner usage rules, and (c) following the associating step, outputting the elements to the printer along with instructions that the printer use, in the printing of such elements, the correct, respectively associated color-toner usage rule(s). From a structural point of view, the invention includes examining structure, associating structure, and output structure designed to perform the basic core methodology steps of the invention.
Methods And Systems For Segmenting A Digital Image Into Regions
Aspects of the present invention relate to methods and systems for segmenting a digital image into regions. A frequency-of-occurrence of image values may be determined excluding a portion of pixels in a digital image. An image value associated with a peak in the frequency-of-occurrence of image values may be identified and associated with an image label. Pixel locations may be labeled based on the associated labels and image values. Additionally, unreliable pixels may be determined and labeled based on the associated labels and image values.

US Classification:
382176
Abstract:
Aspects of the present invention relate to systems, methods and devices for detection of text in an image using an initial text classification result and a verification process. In particular, a support region of a candidate text pixel in a text-candidate map may be expanded to produce a revised text-candidate map. Pictorial regions in the image may be discriminated based on an entropy measure using masking and the revised text-candidate map, and the revised text-candidate map may be refined based on the pictorial regions.
Method And Apparatus For Determining An Orientation Of A Document Including Korean Characters
A method and apparatus for determining an orientation of a document including Korean text are presented. A binarized pixel image is created from the document image. Contiguous pixels are grouped and labeled using a bounding box. A spanning stroke may be detected from a group of the contiguous pixels. The orientation of the document is determined by comparing counts associated with spanning strokes in the left, right, top, and bottom halves of the bounding boxes.

Abstract:
A software-controlled method for minimizing color toner use during copying of a color page by a color copier including (a) examining such a page to identify different pre-selected categories of page-contained image elements, (b) associating, with identified different-categories of such elements, specific, respective, pre-determined color-toner usage rules, and (c) following the associating step, outputting the elements to the copier along with instructions that the copier use, in the copying of such elements, the correct, respectively associated color-toner usage rule(s).
