摘要： An image processing system detects a moving person or other object of interest. The system generates a thresholded difference image by processing a video signal or other type of image signal received from a camera. The difference image is then segmented into regions bounded by vertical lines passing through the image, and silhouette candidates are identified in one or more of the regions. Tensor voting is used to determine saliency values and corresponding tangents for each of the silhouette candidates, and the resulting values and tangents are used to detect the object of interest. In an embodiment in which the object of interest is a moving person, a neck position of the moving person may be detected by analyzing a sum of x-components of tangents along a corresponding silhouette. The detected neck position may then be utilized to determine a head position and a head size for the moving person.

摘要： A virtual PTZ camera is described which forms a virtual image using multiple cameras whose fields of view overlap. Images from the cameras are merged by transforming to a common surface and property-blending overlapping regions to smooth transitions due to differences in image formation of common portions of a scene. To achieve high speed, the images may be merged to a common planar surface or set of surfaces so that transforms can be linear. Image information alone may be used to calculate the transforms from common feature points located in the images so that there is no need for three-dimensional geometric information about the cameras.

摘要： The present invention relates generally to the field of video-camera systems, such as a video conferencing systems, and more particularly to video camera targeting systems that locate and acquire targets using an input characterizing a target and a machine-classification system to assist in target acquisition responsively to that input. In some embodiments, the characterization and classification are employed together with one or more inputs of other modalities such as gesture-control. In one example of the system in operation, an operator is able to make pointing gestures toward an object and, simultaneously speak a sentence identifying the object to which the speaker is pointing. At least one term of the sentence, presumably, is associated with a machine-sensible characteristic by which the object can be identified. The system captures and processes the voice and gesture inputs and re-positions a PTZ video camera to focus on the object that best matches both the characteristics and the gesture. Thus, the PTZ camera is aimed based upon the inputs the system receives and the system's ability to locate the target by its sensors.

摘要： A home control system for automatic detection and warning of abnormal behavior includes a unit for observing behavior in a predetermined area under surveillance, a unit for processing an output of observed behavior from the unit for observing, and a pattern recognition module for recognizing whether the observed behavior is associated with predefined normal behaviors. The detection of predetermined normal behavior in progress leads to a provision of an anticipatory action. Upon recognition that the observed behavior is abnormal, an alarm signal is triggered to remind the user.

摘要： 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.

摘要： 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.

摘要： A video processing system tracks a moving person or other object of interest using a combined audio-video tracking system. The audio-video tracking system comprises an audio locator, a video locator, and a set of rules for determining the manner in which settings of a camera are adjusted based on outputs of the audio locator and video locator. The set of rules may be configured such that only the audio locator output is used to adjust the camera settings if the audio locator and video locator outputs are not sufficiently close and a confidence indicator generated by the audio locator is above a specified threshold. For example, in such a situation, the audio locator output alone may be used to direct the camera to a new speaker in a video conference. If the audio locator and video locator outputs are sufficiently close, the system determines if a confidence indicator generated by the video locator is above a specified level, and if so, the video locator output may be used to adjust the camera settings. For example, the camera may be zoomed in such that the face of a video conference participant is centered in and occupies a designated portion of a video frame generated by the camera.
