Patent number: 10127452Abstract: The filtering tasks that are conventionally applied in a video monitoring application, to distinguish images that may be relevant to the application, are distributed to the image source, or near-source devices. Source devices, such as cameras and playback devices, and near-source devices, such as video concentrators and streaming devices, are configured to include video processing tools that can be used to pre-filter the image data to identify frames or segments of frames that include image information that is likely to be relevant to the receiving video monitoring application. In this manner, the receiving processor need not spend time and resources processing images that are pre-determined to be irrelevant to the receiving application.Type: GrantFiled: May 28, 2015Date of Patent: November 13, 2018Assignee: HONEYWELL INTERNATIONAL INC.Inventors: Tomas Brodsky, Mi-Suen Lee, Carolyn Christine Ramsey, Yun-Ting Lin

Patent number: 8558892Abstract: Blocking zones of a surveillance system are configured to prevent false alarms caused by motion within the zones, while allowing tracking of objects through the zones. An object that first appears within a blocking zone is not considered to be a reportable object until the object leaves the zone. All reportable objects are tracked, without regard to the blocking zones. Objects that remain within their initial blocking zone are not deemed to be reportable objects, and therefore do not generate alarms. If an object initially appears within overlapping zones, the object is not deemed to be reportable until it leaves each of the zones at least once. The blocking zones do not mask the video images, and thus a complete record of activity is available for forensic purposes.Type: GrantFiled: October 20, 2004Date of Patent: October 15, 2013Assignee: Honeywell International Inc.Inventors: Tomas Brodsky, Yun-Ting Lin

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: 7620207Abstract: A method and system is configured to characterize regions of an environment by the likelihoods of transition of a target from each region to another. The likelihoods of transition between regions is preferably used in combination with conventional object-tracking algorithms to determine the likelihood that a newly-appearing object in a scene corresponds to a recently-disappeared target. The likelihoods of transition may be predefined based on the particular environment, or may be determined based on prior appearances and disappearances in the environment, or a combination of both. The likelihoods of transition may also vary as a function of the time of day, day of the week, and other factors that may affect the likelihoods of transitions between regions in the particular surveillance environment.Type: GrantFiled: January 22, 2008Date of Patent: November 17, 2009Assignee: Honeywell International Inc.Inventors: Tomas Brodsky, Yun-Ting Lin

Patent number: 7529646Abstract: A video processing and analysis system is coupled to a building management and control system. The video processing system provides traffic, occupancy, and other information derived from video images of sections of the building and its environs to the building management and control systems. The building systems use this information in a variety of business management applications, including maintenance scheduling, asset replacement, elevator dispatching, HVAC and lighting control, and so on, to reduce operational or maintenance costs, expedite emergency procedures, improve service levels of building facilities, and regulate the building's environmental conditions.Type: GrantFiled: April 4, 2006Date of Patent: May 5, 2009Assignee: Honeywell International Inc.Inventors: Yun-Ting Lin, Tomas Brodsky, Mi-Suen Lee, Carolyn Ramsey
