US Patent:

6904170, Jun 7, 2005
Filed:

May 17, 2002
Appl. No.:

10/150362
Inventors:

Hui Chao - San Jose CA, US
Dan Bloomberg - Palo Alto CA, US
Assignee:

Hewlett-Packard Development Company, L.P. - Houston TX
International Classification:

G06K009/34
US Classification:

382174, 382176, 382179, 382281
Abstract:

A method of document segmentation. Specifically, one embodiment of the present invention discloses a method of document segmentation that performs a plurality of projection profiles of pixel intensities on a document containing a plurality of text lines over a range of angles. A plurality of slope values for a plurality of discrete distances perpendicular to said range of angles is calculated for the plurality of projection profiles. A set of maximum absolute slope values is sorted out from the plurality of slope values. Text lines of first and second type are identified by setting a threshold slope value. Absolute slope values greater than the threshold slope value indicate the plurality of text lines of said first type. Absolute slope values less than the threshold slope value indicate the plurality of text lines of a second type.

Abstract:

Cover authoring systems and methods for automatically composing a final content layout for a cover, including spinal content formatted to accommodate the width and height dimensions of the book spine, are described. By automatically computing the typeface parameter values based upon the selected visual fit model, this cover authoring scheme enables users to avoid the time consuming, laborious and expensive process of manually composing the final cover content layout with a conventional graphics program.

US Patent:

6983084, Jan 3, 2006
Filed:

Aug 28, 2002
Appl. No.:

10/231415
Inventors:

Hui Chao - San Jose CA, US
Dan S. Bloomberg - Palo Alto CA, US
Assignee:

Hewlett-Packard Development Company, LP. - Houston TX
International Classification:

G06K 9/32
US Classification:

382294, 382278
Abstract:

A method of aligning a first page image and a second page image is disclosed. The first page image and the second page image are deskewed. Then, the first page image and the second page image are vertically aligned. In particular, a first vertical data set comprising a plurality of first values each first value based on a horizontal scanline of the first page image is generated. Moreover, a second vertical data set comprising a plurality of second values each second value based on a horizontal scanline of the second page image is generated. One of the first and second vertical data sets is dilated. Then, the first and second vertical data sets are cross-correlated to generate cross-correlation data. A maximum value of the cross-correlation data is determined, whereas the maximum value indicates vertical alignment between the first and second page images. Finally, the first and second page images are horizontally aligned.

US Patent:

7027071, Apr 11, 2006
Filed:

Jul 2, 2002
Appl. No.:

10/186692
Inventors:

Hui Chao - San Jose CA, US
Assignee:

Hewlett-Packard Development Company, L.P. - Houston TX
International Classification:

G09G 5/00
US Classification:

345622, 715513
Abstract:

A computing device comprises a processor and a memory. The processor is operable to select a plurality of related graphics elements for extraction from an electronic document. The selection of the plurality of related graphics elements includes creating a graphics region in the electronic document, and the graphics region includes an expandable area in the document encompassing the plurality of related graphics elements. The memory stores the electronic document from which the plurality of related graphics elements are extracted.

US Patent:

7151547, Dec 19, 2006
Filed:

Nov 23, 2004
Appl. No.:

10/995683
Inventors:

Xiaofan Lin - Sunnyvale CA, US
Hui Chao - San Jose CA, US
Jian Fan - San Jose CA, US
Assignee:

Hewlett-Packard Development Company, L.P. - Houston TX
International Classification:

G09G 5/00
US Classification:

345627, 345655
Abstract:

Systems and methods according to the present invention provide techniques to automatically crop an image to a desired size and non-rectangular crop shape. A non-rectangular crop shape can, for example, be input to an image processing system. The non-rectangular crop shape is then used to process the original image to generate the desired crop.

US Patent:

7421116, Sep 2, 2008
Filed:

Mar 25, 2004
Appl. No.:

10/809234
Inventors:

Jian Fan - Cupertino CA, US
Hui Chao - San Jose CA, US
Assignee:

Hewlett-Packard Development Company, L.P. - Houston TX
International Classification:

G06K 9/00
US Classification:

382164
Abstract:

Systems and methods according to the present invention provide techniques to automatically insert an object from one image into a region of another image. The systems and methods require little or no user interaction to allow efficient re-use and updating of existing images, presentations, documents and the like. An object and a container region are identified. Feasible placement location(s) within the container region for the object, as well as an associated scale factor, are determined. If multiple feasible placement locations are identified for a particular scale factor, then one is selected based upon predetermined criteria. The object can then be inserted into the container region and the resulting composite image stored or, alternatively, parameters can be stored which enable object insertion at a subsequent processing step.

International Classification:

G06F 17/00
US Classification:

715246, 715247, 715243
Abstract:

Methods, systems and machine-readable instructions for processing an electronic document are described. In one aspect, logical blocks that were extracted from the electronic document, including a text block comprising text lines each encompassed by a respective bounding rectangle, are received. Edges of ones of the bounding rectangles are extended to at least one boundary without changing layout relationships among the logical blocks in the electronic document. A text layout boundary is generated from extended and unextended edges of the bounding rectangles. A description of the text layout boundary is stored in a machine-readable medium.
