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: 9678642Abstract: A system and methods for selecting a region of pixels in an image displayed on a touch-sensitive interface is disclosed. The method for selecting the region of pixels is based on determined connectivity of pixels in the image indicating content of the image and includes determining connected pixels on the image representing the content without performing character recognition, detecting a text selection gesture indicative of selecting the region in the image, determining coordinates of the text selection gesture performed on the touch-sensitive interface and selecting the region in the image by bounding a first set of pixels located at a proximity from the coordinates of the text selection gesture.Type: GrantFiled: May 29, 2015Date of Patent: June 13, 2017Assignee: Lexmark International, Inc.Inventors: Stuart Willard Daniel, Ahmed Hamad Mohamed Eid, Shaun Timothy Love

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
