Patent number: 8218859Abstract: This disclosure describes various exemplary method and computer program products for transductive multi-label classification in detecting video concepts for information retrieval. This disclosure describes utilizing a hidden Markov random field formulation to detect labels for concepts in a video content and modeling a multi-label interdependence between the labels by a pairwise Markov random field. The process groups the labels into several parts to speed up a labeling inference and calculates a conditional probability score for the labels, the conditional probability scores are ordered for ranking in a video retrieval evaluation.Type: GrantFiled: December 5, 2008Date of Patent: July 10, 2012Assignee: Microsoft CorporationInventors: Jingdong Wang, Shipeng Li, Xian-Sheng Hua, Yinghai Zhao

Patent number: 8218850Abstract: A method of processing a mammogram image to derive a value for a parameter useful in detecting differences in breast tissue in subsequent images of the same breast or relative to a control group of such images, said derived parameter being an aggregate probability score reflecting the probability of the image being a member of a predefined class of mammogram images, comprises computing for each of a multitude of pixels within a large region of interest within the image a pixel probability score assigned by a trained statistical classifier according to the probability of said pixel belonging to an image belonging to said class, said pixel probability being calculated on the basis of a selected plurality of features of said pixels, and computing said parameter by aggregating the pixel probability scores over said region of interest. Said features may include the 3-jet of said pixels.Type: GrantFiled: December 23, 2008Date of Patent: July 10, 2012Assignee: Synarc Inc.Inventors: Jakob Raundahl, Marco Loog, Mads Nielsen

Publication number: 20120141021Abstract: Systems and methods for automated pattern recognition and object detection. The method can be rapidly developed and improved using a minimal number of algorithms for the data content to fully discriminate details in the data, while reducing the need for human analysis. The system includes a data analysis system that recognizes patterns and detects objects in data without requiring adaptation of the system to a particular application, environment, or data content. The system evaluates the data in its native form independent of the form of presentation or the form of the post-processed data.Type: ApplicationFiled: February 28, 2011Publication date: June 7, 2012Applicant: INTELLISCIENCE CORPORATIONInventors: Robert M. Brinson, JR., Nicholas L. Middleton, Bryan G. Donaldson

Patent number: 8189927Abstract: A method of face categorization and annotation of a face image library includes automatically cropping a face within an acquired digital image or removing one or more non-facial items from the digital image, or both, and thereby generating a full-size face image. The full-size face image is stored with other indicia identifying a person corresponding to the face in a face image library of an embedded device such as a mobile camera phone or other handheld camera device.Type: GrantFiled: March 4, 2008Date of Patent: May 29, 2012Assignee: DigitalOptics Corporation Europe LimitedInventors: Eran Steinberg, Yury Prilutsky, Peter Corcoran, Eric Zarakov, Petronel Bigioi

Patent number: 8175382Abstract: Image enhancement techniques are described to enhance an image in accordance with a set of training images. In an implementation, an image color tone map is generated for a facial region included in an image. The image color tone map may be normalized to a color tone map for a set of training images so that the image color tone map matches the map for the training images. The normalized color tone map may be applied to the image to enhance the in-question image. In further implementations, the procedure may be updated when the average color intensity in non-facial regions differs from an accumulated mean by a threshold amount.Type: GrantFiled: May 10, 2007Date of Patent: May 8, 2012Assignee: Microsoft CorporationInventors: Zicheng Liu, Cha Zhang, Zhengyou Zhang

Patent number: 8160354Abstract: An image-based pattern recognizer and a method and apparatus for making such a pattern recognizer are disclosed. By employing positional coding, the meaning of any feature present in an image can be defined implicitly in space. The pattern recognizer can be a neural network including a plurality of stages of observers. The observers are configured to cooperate to identify the presence of features in the input image and to recognize a pattern in the input image based on the features. Each of the observers includes a plurality of neurons. The input image includes a plurality of units, and each of the observers is configured to generate a separate output set that includes zero or more coordinates of such units.Type: GrantFiled: December 26, 2008Date of Patent: April 17, 2012Assignee: Five Apes, Inc.Inventor: Williams J.
