Patent number: 9336433Abstract: The present invention is a complete end-to-end video face recognition system. The invention performs a track-by-track labeling of all tracks within a video. A novel algorithm Mean Sequence SRC (MSSRC) is applied to a face track to perform video face recognition using a joint optimization to leverage all of the available video data and the knowledge that the face track frames belong to the same individual. Additionally the system constructs a probabilistic affinity graph combining appearance and co-occurrence similarities to model the relationship between face tracks in a video. Finally, using this relationship graph, random walk analysis is employed to propagate strong class predictions among similar face tracks, while dampening weak predictions.Type: GrantFiled: July 24, 2014Date of Patent: May 10, 2016Assignee: UNIVERSITY OF CENTRAL FLORIDA RESEARCH FOUNDATION, INC.Inventors: Enrique Ortiz, Mubarak Shah, Alan Wright

Patent number: 9330447Abstract: An image evaluation device (101) properly evaluating the graininess (or roughness) of an image is provided. The blurer (102) creates a second image b by blurring a first image a. The differentiator (103) creates a third image c presenting the difference between the first image a and second image b. The pixel value of each pixel of the third image c presents the difference in pixel value between the pixels at the same position in the first image a and second image b. The scanner (104) scans the pixels contained in the third image c, obtains the differences in pixel value between adjoining pixels, and obtains the respective probabilities of occurrence of the differences. The calculator (105) calculates the entropy from the obtained, respective probabilities of occurrence of the differences. The outputter (106) outputs the entropy as the evaluation value of the graininess (or roughness) of the first image.Type: GrantFiled: November 15, 2012Date of Patent: May 3, 2016Assignee: Rakuten, Inc.Inventor: Hiromi Hirano

Patent number: 9280721Abstract: A method for ascertaining the position of an edge in or on an object surface region of interest by optical scanning. The reflectivity of the object surface region is evaluated. Light is emitted onto the object surface region under different illumination conditions, in particular different light incidence directions, and in each illumination condition a sequence S1 to Sn of camera images B is recorded. Each camera image B of a sequence S1 to Sn is recorded at another illumination intensity I. Subsequently in each case one reflectivity image R1 to Rn is produced from a plurality of or from all camera images B of a sequence S1 to Sn. Thereafter, a resulting reflectivity image E is produced from a plurality of or from all reflectivity images R1 to Rn by weighted addition, in which resulting reflectivity image E the position of an edge is determined.Type: GrantFiled: March 15, 2013Date of Patent: March 8, 2016Assignee: CARL MAHR HOLDING GMBHInventors: Uwe Nehse, Marco Buechner

Patent number: 9262690Abstract: The present disclosure proposes a method and an electronic device for detecting glare pixels of an image including an object and an electronic device using the same. The method includes the following steps. First, the image is processed to remove overexposed pixels from the image to generate a first image. The first image is processed to remove non-object pixels from the first image to generate an object pixel image. The glare pixels are detected from the object pixel image according to a saturation distribution threshold and an intensity distribution threshold. The present disclosure is able to adjust the saturation distribution threshold and the intensity distribution threshold dynamically and adaptively to satisfy various kinds of objects and ambient lighting conditions so as to improve the probability of successful detection and reduce the probability of false alarms on the glare pixels.Type: GrantFiled: August 27, 2013Date of Patent: February 16, 2016Assignee: HTC CorporationInventor: Chia-Wei Chiu
