Filed:

Sep 4, 2002

Appl. No.:

10/235015

Inventors:

Mark A. Barton - Virginia Beach VA, US

Assignee:

Eastman Kodak Company - Rochester NY

International Classification:

G06K 9/00

US Classification:

382163, 382172

Abstract:

A method for electronic color dropout utilizing spatial context to enhance accuracy comprises scanning a document to produce a color digital image. A thresholding apparatus is applied to the color digital image to produce a bitonal image. A region of the color digital image is selected corresponding to a feature of the bitonal image. An average color for the region is computed and compared to a predetermined dropout color. If the average color matches the predetermined dropout color, the region is erased from the bitonal image. Once it is determined that all features of the bitonal image have been examined, the process is complete. If all the features of the bitonal image have not been examined a region of the color digital image is selected corresponding to a feature of the bitonal image.

Assignee:

Eastman Kodak Company - Rochester NY

International Classification:

H04N 1/46

US Classification:

358509, 358505, 358523

Abstract:

An image scanning system for producing an electronic version of a hardcopy element which is compensated for spectral content of an illumination source in the image scanning system, the image scanning system includes a sensor for receiving light containing the hardcopy element for forming and storing an electronic version of the hardcopy element; a spectral sensor for receiving light from the illumination source and storing an electronic version of spectral contents of the illumination source; and a conversion system for receiving the electronic versions of the illumination source and the hardcopy element and creating a compensation table that compensates subsequent hardcopy elements passed through the conversion system.

Appl. No.:

13/217376

Inventors:

Mark A. Barton - Virginia Beach VA, US

Assignee:

Eastman Kodak Company - Rochester NY

International Classification:

G06K 9/34

US Classification:

382173, 382203

Abstract:

A method for segmenting a composite image containing a plurality of individual images, comprising: locating line segments corresponding to edges in a composite image; defining a plurality of candidate rectangles by identifying sets of four line segments having a first pair of line segments that are parallel to and a second pair of line segments that are perpendicular to the first pair of line segments; identifying image regions that are more than a predefined isolation distance from any of the line segments; identifying a set of enclosing rectangles from among the candidate rectangles for each of the identified image regions; selecting a rectangle for each of the identified image regions from the corresponding set of enclosing rectangles by applying geometric constraints; forming a plurality of sub-images from the composite image by extracting the digital image data corresponding to the selected rectangles; and; and storing the sub-images in a processor-accessible memory.

International Classification:

H04N001/04

US Classification:

358/488000

Abstract:

According to one aspect of the present invention a scanner comprises a transport mechanism for moving a document. A sensor detects a leading edge and a trailing edge of the document. The sensor turns off a drive mechanism when a leading edge of the document is detected. A drive mechanism is started when a trailing edge of a document is detected. A camera scans the document and detects a skew angle of a leading edge and a trailing edge of the document. A front end controller receives a digital signal from the camera and detects the document in a field of the camera within a specified range of pixels.
