PRODUCTS: VIDEO ANALYTICS



PureTech Systems is a world leader in the development and deployment of advanced video analytics / intelligent video solutions for security and safety applications.  All our analytics are internally developed and maintained by our technical staff.  New algorithms and applications are constantly being developed.  The following lists some of our more popular algorithms, each of which can be combined with the others to provide a powerful video security solution.

Object Detection
The ability to detect objects and intrusions using various types of cameras and illuminants while ignoring normal environmental conditions

Object Detection

 

Slew To Cue
Not technically a video algorithm, but the capability to slew a camera or related device directly to an object’s exact position  or to precise geospatial coordinates, followed by the activation of various other video analytic functions.

Automatic PTZ Following (Single Camera)
The most advanced, single camera, automatic  PTZ following on the market.  Designed specifically for outdoor use, this function tracks an objects of interest at varying zoom levels.  It has the ability to change object type mid follow (EX. A person entering a vehicle), continue to follow during obstructed views, changing aspects ratios (crawling, walking, etc) and varied speeds (walking, stopping, running).

Stopped Vehicle
Detection that a vehicle, or other object of interest has stopped within a defined region.

Background Modeling
Background modeling is crucial to every form of analytic behavior intended to be used in outdoor applications.  It affords the capability to recognize traits of the background and remove those attributes from the scene.  This then allows for analysis of the remaining objects.

Detection within a Region
The use of video analytics becomes more powerful when allowing the ability to add additional requirements to the behavior. For example, the entrance or exit from a defined area, or a specific object type of action occurring in that area.

Detection within a Region

 

Car Counting
The ability to count vehicles with directional accuracy, while ignoring pedestrians and environmental conditions.

Shadow Removal
The ability ignore both attached (from a person, car or similar) and unattached shadows (birds, aircraft, clouds).

Live or Recorded Video
Also referred to as a "forensic browser", this is the ability to also apply analytic algorithms to recorded video. This is very valuable when reviewing video for other events associated with an alarm condition.

Live or Recorded Video

 

Object Classification
The identification of objects by type: human, car, truck, boat, unknown.  The subsequent classification can then be used for alarming and display.

Object Classification

 

Image Stabilization
Camera movement is commonplace, annoying and places havoc on most motion detection products.  The Stabilization algorithm removes this video shifting providing a stable video for 3rd party systems and operator viewing.

Image Stabilization

 

Wrong Direction / Speed Threshold
This algorithm can detect the real speed of the vehicle or object, regardless of its orientation to the camera (approaching, departing, moving across scene), as well as, the direction of movement with respect to an area of interest.  Thresholds can then be set to trigger appropriate alarms.

 

Wrong Direction / Speed Threshold

 

Dropped or Thrown Objects
The algorithm looks for objects that have been left in a location, or have been thrown into the view of the camera.

Dropped or Thrown Objects

 

Loitering / Crowd Detection
Often times it is important to not only detect the object, but understand how many objects are present and whether they are remaining in a defined area for a suspicious period of time.  This behavior is covered by Loitering and Crowd Detection.

Loitering / Crowd Detection

 

Camera Tampering
Video analytics can also be used to detect possible tampering with the camera.  The Camera Tampering function looks for the loss of the video image (Due to coverage or disconnection) or excessive movement of the camera (Due to removal or redirection).

Camera Tampering

 

Man Overboard
A specialized detection algorithm to detect jumping or falling targets in both land and water applications.

Man Overboard

 

Real Size
The ability to determine "real" object size. This is in contrast to just determining pixel size. Although an object may encompass a very large number of pixels, this algorithm enables the software to compute the object's size in the real world regardless of how large it may appear in the camera view.

Real Size

 

Scan-to-Target
A specialized camera control algorithm that can be enabled when the redirected camera gets to the scene but finds no intruder. The Scan to Target feature considers a variety of parameters and then commands the camera to scan in an appropriate pattern, the whole time keeping the intelligent video algorithms enabled and searching for the intruder. Once found the target can be followed using PTZ Auto Follow.
