| 20110191195 | INTELLIGENT VIDEO VERIFICATION OF POINT OF SALE (POS) TRANSACTIONS - A method of monitoring a point of sale (POS) transaction including: receiving non video data regarding the POS transaction; defining exceptional transaction rules based at least on predetermined non video POS data events; inferring a potentially exceptional transaction based on a corresponding exceptional transaction rule and the received POS non video data; and verifying the inferred potentially exceptional transaction with video data regarding a corresponding POS transaction. | 08-04-2011 |
| 20100165112 | AUTOMATIC EXTRACTION OF SECONDARY VIDEO STREAMS - The automatic generation ( | 07-01-2010 |
| 20100033567 | AUTOMATIC CALIBRATION OF PTZ CAMERA SYSTEM - In one exemplary embodiment a method calibrates a pan-tilt-zoom (PTZ) camera system. The PTZ camera system may include a PTZ camera. The method may perform at least one of the following steps: determining a radial distortion of the PTZ camera; determining a base focal length of the PTZ camera; determining a zoom and magnification profile of the PTZ camera; determining an actuation delay of the PTZ camera system; determining a pan position mode speed and/or a tilt position mode speed of the PTZ camera; determining a pan velocity profile and/or a tilt velocity profile of the PTZ camera; determining a zoom position profile and/or a zoom duration profile of the PTZ camera; determining a query delay of the PTZ camera system; and determining a minimum query interval of the PTZ camera system. | 02-11-2010 |
| 20090297023 | VIDEO SEGMENTATION USING STATISTICAL PIXEL MODELING - A method for segmenting video data into foreground and background ( | 12-03-2009 |
| 20090158367 | Intelligent video network protocol - Software capabilities of a video analytics device are obtained. The software of the video analytics device is configured. An output from the video analytics device is received. The output is sent to a user device. | 06-18-2009 |
| 20090060278 | STATIONARY TARGET DETECTION BY EXPLOITING CHANGES IN BACKGROUND MODEL - A sequence of video frames of an area of interest is obtained. A first background model of the area of interest is constructed based on a first parameter. A second background model of the area of interest is constructed based on a second parameter, the second parameter being different from the first parameter. A difference between the first and second background models is determined. A stationary target is determined based on the determined difference. An alert concerning the stationary target is generated. | 03-05-2009 |
| 20090060277 | BACKGROUND MODELING WITH FEATURE BLOCKS - Video content analysis of a video may include: modeling a background of the video; detecting at least one target in a foreground of the video based on the feature blocks of the video; and tracking each target of the video. Modeling a background of the video may include: dividing each frame of the video into image blocks; determining features for each image block of each frame to obtain feature blocks for each frame; determining a feature block map for each frame based on the feature blocks of each frame; and determining a background feature block map to model the background of the vide based on at least one of the feature block maps. | 03-05-2009 |
| 20090041297 | Human detection and tracking for security applications - A computer-based system for performing scene content analysis for human detection and tracking may include a video input to receive a video signal; a content analysis module, coupled to the video input, to receive the video signal from the video input, and analyze scene content from the video signal and determine an event from one or more objects visible in the video signal; a data storage module to store the video signal, data related to the event, or data related to configuration and operation of the system; and a user interface module, coupled to the content analysis module, to allow a user to configure the content analysis module to provide an alert for the event, wherein, upon recognition of the event, the content analysis module produces the alert. | 02-12-2009 |
| 20080291278 | Wide-area site-based video surveillance system - A computer-readable medium contains software that, when read by a computer, causes the computer to perform a method for wide-area site-based surveillance. The method includes receiving surveillance data, including view targets, from a plurality of sensors at a site; synchronizing the surveillance data to a single time source; maintaining a site model of the site, wherein the site model comprises a site map, a human size map, and a sensor network model; analyzing the synchronized data using the site model to determine if the view targets represent a same physical object in the site; creating a map target corresponding to a physical object in the site, wherein the map target includes at least one view target; receiving a user-defined global event of interest, wherein the user-defined global event of interest is based on the site map and based on a set of rules; detecting the user-defined global event of interest in real time based on a behavior of the map target; and responding to the detected event of interest according to a user-defined response to the user-defined global event of interest. | 11-27-2008 |
| 20080240616 | Automatic camera calibration and geo-registration using objects that provide positional information - A video sequence of a field of view within an environment is received. Targets are detected in the video sequence. Target geo-positional information is received. Correspondences between the targets detected in the video sequence and the target geo-positional information are determined and used to calibrate the camera and to geo-register a field of view of the camera. | 10-02-2008 |
