Patent number: 9747509Abstract: A mobile device with camera automatically captures an image of a check from a video sequence. A computing application assesses quality metrics of a frame of the video and, if acceptable, initiates capture of the check in that frame without user selection. Metrics include an aspect ratio of the check, image quality of the routing transit symbols that delineate a routing transit number on a MICR line of the check, distances between the routing transit symbols and to an edge of the check, recognition of digits of the routing transit number, checksum of the routing transit numbers, and image sharpness. Other embodiments note cropping of the check from the background of the image, properly orienting the check for viewing, and providing color coded visual feedback to users about the quality of the image frame about the check, to name a few.Type: GrantFiled: February 27, 2015Date of Patent: August 29, 2017Assignee: LEXMARK INTERNATIONAL, INC.Inventors: Ahmed Hamad Mohamed Eid, Tomasz Jan Cholewo, Stuart Willard Daniel, Stacy Lee Simpson

Patent number: 9449238Abstract: Systems and methods search pixels of source images and compare them to pixels of templates. Best matches correlate to objects in the image. That environmental conditions impact the appearance of objects, best matching scores suffer under poor lighting and other adverse conditions. Improving scores includes augmenting traditional correlation techniques with object features extracted from the source image and matching them to templates corresponding to the features. Certain embodiments contemplate corrupting pixels of image templates corresponding to objects with pixels extracted from the source image corresponding to features. Representative features include corners, edges, ridges, points/regions of interest, etc. Other embodiments note augmented correlation as a computing application and computing devices therefore, including cameras for capturing images and displaying results to users.Type: GrantFiled: April 30, 2014Date of Patent: September 20, 2016Assignee: LEXMARK INTERNATIONAL, INC.Inventors: Ahmed Hamad Mohamed Eid, Tomasz Jan Cholewo, Edward Earl Rippetoe, II

Patent number: 6867883Abstract: A color gamut in a first color space is expanded to utilize a larger gamut in a second color space. The gamut in the first color space is first converted by black generation or geometric distortion to a gamut in a second color space. The gamut in the second color space is converted by forward mapping to a gamut in a third color. The gamut in the third color space is expanded by linear rescaling. Finally, the linearly rescaled gamut is mapped to a gamut in the second color space through inverse modeling to form a final color gamut. The final color gamut utilizes the gamut available in the second color space, which is larger than the gamut available in the first color space.Type: GrantFiled: January 21, 2000Date of Patent: March 15, 2005Assignee: Lexmark International, Inc.Inventors: Tomasz Jan Cholewo, Raymond Edward Clark

Patent number: 6480301Abstract: The method includes identifying a set of points defining a gamut for a color image or image forming device, selecting a parameter &agr;, and computing the gamut boundary of the color image from the set of points and &agr; using Delaunay triangulation. The system includes a processing unit, a memory, and software operative on the processing unit. The software is capable of identifying a gamut boundary for the image, identifying a gamut boundary for the image forming unit, and calculating the percentage of colors in the image capable of being rendered by the image forming unit from the gamut boundary for the image and the image forming unit. The software is also capable of identifying an alpha shape associated with a color gamut and calculating a color gamut volume. The alpha shape includes a plurality of tetrahedra and each of the plurality of tetrahedra has a volume. The plurality of volumes are summed to generate the color gamut volume.Type: GrantFiled: November 15, 1999Date of Patent: November 12, 2002Assignee: Lexmark International, Inc.Inventor: Tomasz Jan Cholewo
