Publication number: 20120327246Abstract: A system for automatically acquiring high-resolution images by steering a pan-tilt-zoom camera at targets detected in a fixed camera view is provided. The system uses automatic or manual calibration between multiple cameras. Using automatic calibration, the homography between the cameras in a home position is estimated together with the effects of pan and tilt controls and the expected height of a person in the image. These calibrations are chained together to steer a slave camera. The manual calibration scheme steers a camera to the desired region of interest and calculates the pan, tile and zoom parameters accordingly.Type: ApplicationFiled: September 4, 2012Publication date: December 27, 2012Applicant: INTERNATIONAL BUSINESS MACHINES CORPORATIONInventors: Andrew William Senior, Sharathchandra Pankanti, Arun Hampapur, Lisa Marie Brown, Ying-Li Tian

Publication number: 20120027304Abstract: The invention provides an improved method to detect semantic attributes of human body in computer vision. In detecting semantic attributes of human body in computer vision, the invention maintains a list of semantic attributes, each of which corresponds to a human body part. A computer module then analyzes segments of a frame of a digital video to detect each semantic attribute by finding a most likely attribute for each segment. A threshold is applied to select candidate segments of the frame for further analysis. The candidate segments of the frame then go through geometric and resolution context analysis by applying the physical structure principles of a human body and by analyzing increasingly higher resolution versions of the image to verify the existence and accuracy of parts and attributes.Type: ApplicationFiled: July 28, 2010Publication date: February 2, 2012Applicant: International Business Machines CorporationInventors: Lisa Marie Brown, Rogerio Schmidt Feris, Arun Hampapur, Daniel André Vaquero

Patent number: 7777615Abstract: A system for assisting the alignment of a hitch pin mounted on the rear of a vehicle with a hitch socket mounted on the front of a trailer. The system includes a camera mounted to the vehicle and positioned to capture an image rearwardly of the vehicle. A video display is contained within the vehicle which displays the image captured by the camera. A processor is also contained in the vehicle which calculates a preferred path of travel of the vehicle to position the hitch pin in alignment with the hitch socket. The processor is programmed to provide instructions to an operator of the vehicle of the required steering to maintain the vehicle on the preferred path of travel. The processor recalculates the preferred path of travel whenever the vehicle veers from the preferred path of travel by a preset threshold.Type: GrantFiled: March 20, 2008Date of Patent: August 17, 2010Assignees: Toyota Motor Engineering & Manufacturing North America, Inc., Denso International America, Inc., Denso CorporationInventors: Masato Okuda, Christian Arthur Trager, Lisa Marie Brown, Michael Wiegand, Tanemichi Chiba, Christopher Kurpinski, Jeffrey Edward Angeliu, Hirohiko Yanagawa, Yoshihisa Sato, Toshihiro Wakamatsu, Justin McBride, Thomas Keeling

Patent number: 7529388Abstract: Techniques for tracking entities using a single overhead camera are provided. A foreground region is detected in a video frame of the single overhead camera corresponding to one or more entities. It is determined if the foreground region is associated with an existing tracker. It is determined whether the detected foreground region is the result of at least one of a merger of two or more smaller foreground regions having corresponding existing trackers and a split of a larger foreground region having a corresponding existing tracker when the detected foreground region is not associated with an existing tracker. The detected foreground region is tracked via at least one existing tracker when the foreground region is associated with an existing tracker or the foreground region is the result of at least one of a merger and a split.Type: GrantFiled: May 5, 2008Date of Patent: May 5, 2009Assignee: International Business Machines CorporationInventors: Lisa Marie Brown, Arun Hampapur, Andrew William Senior, Ying Li Tian, Senem Velipasalar

Patent number: 7480414Abstract: Methods and apparatus are provided for normalizing objects across a plurality of image viewpoints. A set of classification results are obtained for a given object class across a sequence of images for each of a plurality of viewpoints. The classification results are each comprised of a position of one of the objects in the image, and at least one projected property of the object at that position. Normalization parameters are then determined for each of the viewpoints by fitting a high order model to the classification results to model a change in the projected property. The high order model may implement a least squares fit of a second order polynomial to the classification results. The normalization parameters may be used to compute normalized features and normalized training data for object classification.Type: GrantFiled: October 14, 2004Date of Patent: January 20, 2009Assignee: International Business Machines CorporationInventors: Lisa Marie Brown, Arun Hampapur, Ying-Li Tian, Chiao-Fe Shu, Andrew William Senior

Patent number: 7447331Abstract: A system and method for generating a viewable video index for low bandwidth applications are provided. The exemplary aspects of the present invention solve the problems with the prior art systems by incorporating information for generating a viewable representation of the video data into the index, thus generating a viewable video index. The viewable video index contains information for generating a visual representation of moving objects in the video data, a visual representation of the background of the video capture area, i.e. the scene, a representation of the object trajectory, a representation of the object attributes, and a representation of detected events. The result is that the viewable video index may be transmitted to a low bandwidth application on a client device and may be used along with associated object and background models to generate a representation of the actual video data without requiring that the original video data itself be streamed to the client device.Type: GrantFiled: February 24, 2004Date of Patent: November 4, 2008Assignee: International Business Machines CorporationInventors: Lisa Marie Brown, Jonathan H.
