Patent number: 7876361Abstract: To calibrate images from an overhead camera, two equal-length reference lines at different heights relative to the floor plane are imaged. By comparing the resultant image-width of each of these lines in the view provided by the camera, the effective focal point of the camera is determined. In a preferred embodiment, a doorframe is used to provide equal-length lines at different heights parallel to the floor. The threshold of the doorway at the floor plane is used as a reference plane, and a parallel calibration line at a known/measured height in the doorway is defined. The image produced by a vertically oriented camera of these two equal length lines will show a longer line at the elevated position, the different widths of the images of these lines being dependent upon the camera's effective focal point. From these two projections of the equal-length lines at different heights, the camera's focal point distance from the reference floor plane is determined.Type: GrantFiled: January 11, 2006Date of Patent: January 25, 2011Assignee: Honeywell International Inc.Inventors: Yun-Ting Lin, Tomas Brodsky, Mi-Suen Lee

Patent number: 7778444Abstract: An image processing system (250) and method (300) are disclosed for correcting a head pose in a video phone image, so that a frontal view is presented on a display. A disclosed head pose corrector (250) estimates the orientation of a head pose and adjusts the orientation of the head pose, if necessary, to present a frontal view. The orientation of the head pose is adjusted by generating a three dimensional model of the face surface and adjusting the orientation of the three dimensional face model to provide the desired frontal view. The head pose corrector (250) may be included in a video phone (100) to correct the head pose of transmitted or received images (or both) or may be included in a server on a network to automatically adjust the head shots of one or more participants to a video phone communication.Type: GrantFiled: December 8, 2003Date of Patent: August 17, 2010Assignee: Koninklijke Philips Electronics N.V.Inventors: Mi-Suen Lee, Yun-Ting Lin, Miroslav Trajkovic, Vasanth Philomin

Patent number: 7619648Abstract: A surveillance system allows a user to characterize the user's environment and/or the user s surveillance application, via a selection from among a variety of predefined environments and/or applications. Preferably, the selection is from among a variety of scene configurations, such as the expected number and type of targets in a typical scene, the lighting conditions of the scene, and so on. The selected environments and/or applications effect a determination of the parameters that are used in the various algorithms and processing modules within the surveillance system. Because the selection is preferably from a variety of common scene configurations, no technical skills are required to effect an optimization of the performance of the surveillance system for a particular environment.Type: GrantFiled: July 1, 2008Date of Patent: November 17, 2009Assignee: Honeywell International Inc.Inventor: Mi-Suen Lee

Patent number: 7412202Abstract: A recommendation system is disclosed that generates recommendations for one or more items based on user preferences and one or more environmental factors. The user's preferences are learned under various environmental conditions using an environmental data collection system. The observed environmental conditions may include, for example, location, characteristics of the location, weather or characteristics of the user's motion, such as a rate of movement. For each positive and negative behavioral example, a number of attributes of the selected item are classified in the user profile together with the prevailing environmental conditions. When recommending an item, the disclosed recommender retrieves the user preferences and evaluates the current environmental conditions. A recommendation score can be generated for each available item based on the user's demonstrated preferences under similar environmental conditions, such as in the same or a similar geographic area or under similar weather conditions.Type: GrantFiled: April 3, 2001Date of Patent: August 12, 2008Assignee: Koninklijke Philips Electronics N.V.Inventors: Srinivas Gutta, Mi-Suen Lee, Lalitha Agnihotri

Patent number: 7369680Abstract: A system and apparatus are disclosed for modeling patterns of behavior of humans or other animate objects and detecting a violation of a repetitive pattern of behavior. The behavior of one or more persons is observed over time and features of the behavior are recorded in a multi-dimensional space. Over time, the multi-dimensional data provides an indication of patterns of human behavior. Activities that are repetitive in terms of time, location and activity, such as sleeping and eating, would appear as a Gaussian distribution or cluster in the multi-dimensional data. Probability distribution functions can be analyzed using known Gaussian or clustering techniques to identify repetitive patterns of behavior and characteristics thereof, such as a mean and variance. Deviations from repetitive patterns of behavior can be detected and an alarm can be triggered, if appropriate.Type: GrantFiled: June 28, 2002Date of Patent: May 6, 2008Assignee: Koninklijke Phhilips Electronics N.V.Inventors: Miroslav Trajkovic, Mi-Suen Lee, Serhan Dagtas, Srinivas Gutta, Tomas Brodsky, Vasanth Philomin, Yun-Ting Lin, Hugo Strubbe

Patent number: 7298871Abstract: A system and method for automatically controlling systems and devices in a local environment, such as a home. The system comprises a control unit that receives images associated with one or more regions of the local environment. The one or more regions are each serviced by one or more servicing components. The control unit processes the images to identify, from a group of known persons associated with the local environment, any one or more known persons located in the regions. For the regions in which one or more known person is identified, the control unit automatically generates a control signal for at least one of the servicing components associated with the region, the control signal reflecting a preference of at least one of the known persons located in the respective region.Type: GrantFiled: June 7, 2002Date of Patent: November 20, 2007Assignee: Koninklijke Philips Electronics N.V.Inventors: Mi-Suen Lee, Hugo Strubbe

Patent number: 7254296Abstract: An optical assembly incorporates a compact and efficient lens for coupling a beam of light from an optical device to an optical fiber. The lens includes a curved reflecting surface and a focusing surface. The lens is positioned to receive and internally reflect the beam of light from the optical device toward the focusing surface. The focusing surface in turn focuses the reflected beam into the end of an optical fiber. The curved surface may include a reflective coating for transmitting a portion of the beam toward a monitoring unit which is used to monitor a parameter of the beam. The optical assembly may further include a platform for supporting the optical device, the lens, the optical fiber and the monitoring unit.Type: GrantFiled: January 13, 2004Date of Patent: August 7, 2007Assignee: SAE Magnetics (Hong Kong) LimitedInventors: Sio Kuan Lam, Ka Suen Lee, Shing Lui Lau, Kwok Sing Cheng, Mark Wing-Keung Mak, Fuk Kay Frank Tong
