The controller operable to analyze each of the plurality of candidate images to determined a numeric thumbnail based on a number of identified features in each of a plurality of grid elements of an array and a sum total number of all identified features in the array, calculate a similarity score between one of the plurality of determined numeric thumbnails and each of the remaining plurality of determined numeric thumbnails; and generate a logical group image order as a function of the highest similarity score between the one of the plurality of determined numeric thumbnails and each of the remaining plurality of determined numeric thumbnails.Type: GrantFiled: August 29, 2011Date of Patent: January 6, 2015Assignee: DST Technologies, Inc.Inventor: Kevin W.

Patent number: 8909563Abstract: Methods, systems, and articles of manufacture for annotating of an image are disclosed. These include scoring the image using a plurality of trained classifiers, wherein each of the trained classifiers corresponds to at least one of a plurality of image groups clustered based upon image similarity, and wherein each image group is associated with a set of weighted labels; selecting one or more of the image groups based upon the scoring; aggregating one or more sets of weighted labels associated with the selected one or more image groups; and annotating the image using the aggregated one or more sets of weighted labels.Type: GrantFiled: June 17, 2011Date of Patent: December 9, 2014Assignee: Google Inc.Inventors: Yushi Jing, Yi Liu, David Tsai

Publication number: 20140334733Abstract: A system and method to detect similarities between images. The system and method allow comparisons between a query image and one or more catalog images in a manner that is resilient to scanning, scaling, rotating, cropping and other distortions of the query image. The system includes an image processing module that determines and/or calculates principle features of a catalog image and constructs a feature vector using one or more of the principle features. The system also includes a matching module that matches a query image to one or more catalog images. The system finds matches based on a distance measure of features present in the query image and features present in the catalog images.Type: ApplicationFiled: December 26, 2013Publication date: November 13, 2014Inventors: Uri Lavi, Eli Goz, Gregory Begelman

Patent number: 8878923Abstract: In an imaging device having an objective and a stage for holding a sample to be imaged, a method for autofocusing is presented. The method includes determining a measured focus value corresponding to at least a first of a plurality of logical image segments. Further, the method includes imaging the first logical image segment using the measured focus value. The method also includes determining a predicted focus value for a second of the plurality of logical image segments using the measured focus value and a stored focus variation parameter. In addition, the method includes imaging the second logical image segment using the predicted focus value.Type: GrantFiled: April 13, 2009Date of Patent: November 4, 2014Assignee: General Electric CompanyInventors: David LaVan Henderson, Kevin Bernard Kenny, Siavash Yazdanfar

Patent number: 8861816Abstract: A method of processing graphical image data representing optically scanned medication-related units may include receiving image data generated responsive to disposal of the units on a tray disposed a distance from an image acquisition component, the image data including data indicative of visually observable features of the units disposed on the tray. The method further includes comparing at least two features among the visually observable features from the image data to reference data indicative of corresponding features of reference units. The reference data is selected for comparison based on an identification of the reference data as corresponding to a prescription being processed. The reference data includes data indicative of features of the reference units extracted from images captured using hardware corresponding to hardware used to generate the image data. The method further includes generating a likelihood rating for each of the at least two features based on the comparing.Type: GrantFiled: December 5, 2011Date of Patent: October 14, 2014Assignee: Illinois Tool Works Inc.Inventors: David A. Lang, David A. Yanez, Nelson D. Tarr, Chris S. Burt

Patent number: 8855421Abstract: Methods and apparatuses for identifying an image based on Embedded Media Marker (EMM) identification. A hierarchal comparison including a first coarse comparison and a second refining comparison is used. The first coarse comparison compares an image with an EMM to images in a database at a low resolution. The results are fed to the second refining comparison, which conducts a comparison at a higher resolution than the first coarse comparison. By utilizing this hierarchical comparison approach, it is possible to identify the image with fewer false positives.Type: GrantFiled: April 25, 2011Date of Patent: October 7, 2014Assignee: Fuji Xerox Co., Ltd.Inventors: Xin Yang, Qiong Liu, Chunyuan Liao
