Abstract: A method and apparatus are disclosed for generating and maintaining enhanced background models for use in background-foreground segmentation. Background models are modified to contain an indication of objects that are typically stationary. Thereafter, if an object moves and has been previously identified as an object that is typically stationary, the object will not unnecessarily be identified as part of the foreground during background-foreground segmentation. In an exemplary implementation, moving objects are classified into two sets. A first set includes objects that typically move independently and a second set includes objects that are typically stationary. Generally, once an object is assigned to the second (stationary object) set, the object will remain in the background, even if the object is moved (normally, movement of the object would cause the object to become part of the foreground).

Abstract: A system and method for alerting a driver of an automobile to a traffic condition. The system comprises at least one camera having a field of view and facing in the forward direction of the automobile. The camera captures images of the field of view in front of the automobile. A control unit receives images of the field of view from the camera and identifies objects therein of a predetermined type. The control unit analyzes the object images of at least one predetermined type to determine whether one or more of the identified objects present a condition that requires the driver's response. A display receives control signals from the control unit regarding the one or more of the objects that present a condition that requires the driver's response. The display displays an image of the object to the driver that is positioned and scaled so that it overlays the actual object as seen by the driver, the displayed image of the object enhancing a feature of the actual object to alert the driver.

Abstract: 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.

Abstract: A camera system comprising a camera, a monitor, an image detector, a touch screen, and a remote control. The monitor displays a field of view of a lens of the camera. The image detector provides a viewer image to the remote control whereby the remote control can determine a desired image within the field of view that the viewer is gazing upon. The touch screen enables a viewer of the monitor to point to the desired image of the field of view and provides signal(s) indicative of the pointing. The remote control is operable to activate various drives to pan and/or tilt the camera, or to zoom and/or focus the lens to the desired image and to follow any movement of the image within the field of view.
