In some embodiments, a non-transitory processor-readable medium stores code representing instructions to cause a processor to smooth a current image of a scene to produce a smoothed image and subtract pixel values of a background image of the scene from corresponding pixel values of the smoothed image to produce an altitude difference image. Pixel values of the altitude difference image are weighted to produce a weighted difference image. The weighted difference image is convolved to produce a convoluted difference image. A threshold is applied to each pixel of the convoluted difference image to produce a thresholded difference image. Pixels having a value less than the threshold are removed from the thresholded difference image and classified as background pixels. Foreground pixels are determined based on the thresholded difference image.

A method and apparatus for visualizing correlations among and between objects and events stores objects, events, and correlations to form a query space. The query space includes a correlation graph having a node for each of the objects and events, and an edge for each of the correlations. Each of the edges in the correlation graph connects either two of the nodes, or one of the nodes and another one of the edges. In response to a query performed in the query space, the present invention visualizes at least a subset of the nodes and edges to form a result space.

A security system comprises a computer network and a plurality of sensors each connected to the computer network at a respective network address and each generating sensing data. A managing component is connected with the network and communicates with the sensors by access thereof through the associated network address on the network, and processes sensor information received from said sensors. The managing component has a display with an interface screen showing to a user all the sensors in the security system, and an input device through which the user can enter interactive instructions to the managing component. The managing component controls communications to and from the sensors and has a rules engine storing rules therein. Each of the rules being associated with a respective device on the network, and causing the managing computer to take an action in response to output from at least one of the devices.

A method for remote event notification over a data network is disclosed. The method includes receiving video data from any source, analyzing the video data with reference to a profile to select a segment of interest associated with an event of significance, encoding the segment of interest, and sending to a user a representation of the segment of interest for display at a user display device. A further method for sharing video data based on content according to a user-defined profile over a data network is disclosed. The method includes receiving the video data, analyzing the video data for relevant content according to the profile, consulting a profile to determine a treatment of the relevant content, and sending data representative of the relevant content according to the treatment.

In some embodiments, a non-transitory processor-readable medium stores code representing instructions to cause a processor to receive a first image of a visual pattern from a sensor. The visual pattern encodes at least one compression parameter, at least one capture parameter or at least one video analytic parameter to be applied to the sensor. The code represents instructions to cause the processor to apply the at least one compression parameter, the at least one capture parameter or the at least one video analytic parameter to the sensor. The code further represents instructions to cause the processor to receive a second image from the sensor. The sensor captures or analyzes the second image according to the at least one compression parameter, the at least one capture parameter or the at least one video analytic parameter.
