Filed:
Aug 17, 1992
Appl. No.:
7/931654
Inventors:
Joseph M. Capo - West Bloomsfield MI

Assignee:
Unisys Corporation - Blue Bell PA
International Classification:
G06K 936
US Classification:
382 41
Abstract:
A pipelined image processor generates an image of the information contained on first and second portions of a document. The pipelined image processor includes a first pipe for processing information contained on the first portion of the document, and second pipe for processing information contained on the second portion of the document. The pipes receive the output from two camera assemblies which are used for generating an electrical signal in response to information contained on the document, an image digitizer for generating digitized information from the electrical signal by the means for generating an electrical signal. In addition, both pipes also include a resequencer for generating resequenced information from the digitized information, as well as an image processor for generating processed information from the resequenced information. Finally, the first and second pipes include a transposer/compressor assembly for generating transposed and compressed information from the processed information, and a compressed data buffer for storing the transposed and compressed information.

Assignee:
Unisys Corporation - Bluebell PA
International Classification:
G06K 938
US Classification:
382 51
Abstract:
A digital image preprocessing method for eliminating background patterns and scenes from digitized gray level document image data. The method accepts multi-gray level image data as input and produces a gray level output image containing a "white" background. Document image backgrounds are eliminated (or suppressed) by computing a separate (and typically different) threshold value for each gray level pixel of the original document image. Input image pixels whose gray level is greater (brighter) than the threshold value are assumed to be background picture data and are modified to be "white" pixels in the output image. The pixel threshold value is determined dynamically pixel-to-pixel based on gray level pixel data observed within the input image. Additionally, the pixel threshold can be automatically controlled to insure retention of written and/or printed information present in the input image. Threshold control is accomplished by specifying a print contrast signal (PCS) parameter to the image preprocessing method.

Assignee:
W. L. Gore & Associates, Inc. - Newark DE
International Classification:
A61B 17/22
US Classification:
606159
Abstract:
The present invention relates to medical cutting tools for treating aortic septal dissections. The cutting tool is provided with a delivery catheter and has a remotely actuated cutting blade or cutting wire component. The cutting tool is provided with at least one displacement element. The displacement element assists in placement of the cutting tool at a desired location. The displacement element also assists in maintaining contact between the cutting blade and tissue being cut.

US Patent:
5093871, Mar 3, 1992
Filed:

Assignee:
Unisys Corporation - Blue Bell PA
International Classification:
G06K 936
US Classification:
382 51
Abstract:
Apparatus for processing digitized images which contain useful image formation data and background features a background supression scheme used to convert each pixel value to preselected values in a smaller range in order to facilitate data processing such as compression and scaling. Provision is made for generating an adaptive or dynamic threshold value, as well as a much more stable background reference threshold value.

Assignee:
Unisys Corporation - Bluebell PA
International Classification:
G06K 954
US Classification:
382 49
Abstract:
A pipelined image processor is disclosed which contains a diagnostic apparatus which, under normal processing conditions, is coupled to and is in communication with resequencer, image processor, and transposer/compressor assemblies contained within the pipelined image processor. The diagnostic apparatus of this invention causes a diagnostic test pattern to be sent to the re-sequencer and image processor entities of the pipelined image processor and monitors the response thereof. This response is then used to detect faults which have occurred in these entities.
