Patent number: 9218532Abstract: A light receiver records images of light beams originating from a neighborhood of lights, and demodulates identifiers (IDs) from them at determined image positions. The receiver retrieves a set of neighbor IDs for each demodulated ID and a real-world position of the corresponding light. The receiver cross-references the demodulated IDs against the retrieved sets of neighbor IDs to reveal errors in the demodulated IDs. The receiver corrects the errors to produce correct IDs each indexing a real-world position that is correctly matched to one of the determined light beam positions. The receiver determines a position of the receiver relative to the light transmitter based on the correctly matched real-world and determined light beam positions.Type: GrantFiled: September 28, 2012Date of Patent: December 22, 2015Assignee: Intel CorporationInventor: Richard D.

Patent number: 9218815Abstract: Disclosed herein are systems, methods, and non-transitory computer-readable storage media for performing speaker verification. A system configured to practice the method receives a request to verify a speaker, generates a text challenge that is unique to the request, and, in response to the request, prompts the speaker to utter the text challenge. Then the system records a dynamic image feature of the speaker as the speaker utters the text challenge, and performs speaker verification based on the dynamic image feature and the text challenge. Recording the dynamic image feature of the speaker can include recording video of the speaker while speaking the text challenge. The dynamic feature can include a movement pattern of head, lips, mouth, eyes, and/or eyebrows of the speaker. The dynamic image feature can relate to phonetic content of the speaker speaking the challenge, speech prosody, and the speaker's facial expression responding to content of the challenge.Type: GrantFiled: November 24, 2014Date of Patent: December 22, 2015Assignee: AT&T Intellectual Property I, L.P.Inventors: Ann K.

Patent number: 9135507Abstract: A method for searching a building roof facet and reconstructing a roof structure line, in which the searching is performed automatically and without limitation of how slope of the roof facet, and the building structure line is constructed through aerial imagery. At first, lidar point clouds on the roof are extracted to compose a roof facet by using coplanarity analysis, and the roof is differentiated to a possible flat roof and a pitched roof. An optimal roof facet is obtained by analyzing lidar point clouds to overcome the low pitched facet issue. A relationship of a roof facet on a 2-dimensional space is analyzed to ascertain an area of a roof structure line. An initial boundary is generated. Line detection is performed on the images and a roof structure line segment is composed. All the structure line segments are used to reconstructing a 3-dimensional building pattern in object space.Type: GrantFiled: July 11, 2013Date of Patent: September 15, 2015Assignee: NATIONAL CENTRAL UNIVERSITYInventors: Liang-Chien Chen, Yun-Jou Lin

Patent number: 9111343Abstract: Systems, methods and computer program products for mapping coordinates of various imaging stations are described. In some implementations, cells (e.g., red blood cells) in a biological specimen can be used for determining the mapping information between the imaging stations. The use of cells allows a target image (e.g., an image of a sub-region of cells in the biological specimen) taken by one imaging station to be pattern-matched to a reference image (e.g., an image showing a larger region of cells in the biological specimen that also includes the sub-region) taken by another imaging station. Once the target image is matched to the reference image, point by point correspondence (and therefore coordinates) between the target image and the reference image can be established for computing the coordinate transformation to map the imaging stations.Type: GrantFiled: January 18, 2011Date of Patent: August 18, 2015Assignee: Roche Diagnostics Hematology, Inc.Inventors: Michael Zahniser, Russell Zahniser
