Image Analyzers

Image analyzers include the Tools Activity Detection (AD), the Video Motion Detection (VMD), the movement detection Video Motion Extended (VMX), the Scene Validation (SV), the AI-Connect, the Analytic Host , the Number Plate Recognition (ANPR) and the License Plate Recognition (LPR) .

For all image analysis applications, the server connections must be configured and the media channels to be analyzed must be selected. You also need to define which applications will be included in the analysis. These settings are made in the VCA Setup Editor for the analysis application ANPR and LPR. For AD, VMD, VMX, SV and AI-Connect these settings can be made via the Analytic Host.

Drawing Zones

Zones are created in the applications of G-Tect, in Activity Detection (AD) and Privacy Zones.

In these applications zones are drawn as polygons. This makes it possible to mark more complex shapes in the image and zones can be moved, made larger or smaller or changed in shape at any time. They can be copied, cut, duplicated and pasted, too.

Marked zones look different in the different applications:

Application

Polygonal zones may overlap. Each zone retains your settings.
Intersections can not be configured separately.

Draw a Polygon

  1. Click to create a node.
  2. Move the cursor to another point in the image and click again. The two points are connected.

  3. Move the cursor to another point in the image and click again. The marked points now form a surface.

  4. You can now add as many points as you want for this polygon.

  5. You stop drawing the polygon by clicking on its starting point.

Example

Move a Polygon

  1. Move the cursor over the polygon.

  2. When the mouse pointer changes shape, click the polygon and drag it to the desired location.

Change the Shape/Size of the Polygon

  1. Move the cursor to a node.

  2. Hold the left hand mouse button down, and drag the node in the desired direction.

Add Node

You can always add a node to the polygon. Move the cursor to the desired location on the perimeter of the polygon and click with the left mouse button.

Delete Node

To delete a node, move the cursor over the node and right click.

Context Menu of a Polygon

When you move the cursor over a polygon and right click, a context menu with the following commands appears:

Command

Description

Delete

The polygon will be deleted.

Duplicate

The polygon is duplicated.

Cut

The polygon is cut out.
It can be added here, at another location or in another application using the Paste command

Copy
