1.4 Intelligent Video Analysis

Bosch IVA 4.0 (Intelligent Video Analysis), with the auxiliary function IVA 4.0 Flow is an algorithm that detects certain properties and the behavior of objects in a scene monitored by a video camera and from this generates alarm events that, in turn, can be processed in a CCTV system. Recording with activated IVA 4.0 settings is required in order to be able to later search through the video material quickly and purposefully using this algorithm. IVA 4.0 makes it possible to capture and evaluate directional movement of objects in such a way that false alarms are prevented to a large extent. IVA 4.0 adapts automatically to changing environmental conditions and is therefore largely non-sensitive to perturbing influences such as rain and tree movement. Specifically when used for a forensic search, IVA 4.0 allows moving objects to be filtered according to their color. Using the IVA 4.0 algorithm, extensive video material can be specifically searched for objects with particular color properties.
New IVA 4.0 Functions
Head detection: Objects can be identified as people by means of typical features. – Similarity search: Objects can be detected on the basis of their similarity to other objects
that have already been classified.
IVA 4.0 Flow auxiliary function: A uniform optical flow is detected largely irrespective of
the structure of the background and the size of individual objects. A flow in the opposite direction to the general direction of movement can also be defined as an alarm-triggering event. IVA 4.0 Flow is used to detect uniform movement flows and movements against the general flow.

2 Requirements

2.1 Setup

The easiest way to set up IVA 4.0 and IVA 4.0 Flow is using the Configuration Manager program. This must be installed on a Windows PC that can communicate with the respective device over a network. You will find a current version of the Configuration Manager program on the CD received when you purchased the license. Operational requirements for the Configuration Manager program can be found in the documentation supplied. Configuration Manager does not have to be licensed. No additional programs are required to analyze live images. Alternatively, you can also configure IVA 4.0 and IVA 4.0 Flow using the Web browser view of the device.
IVA 4.0-Compatible Senders and Cameras
IVA 4.0 is also available on the following devices: – Dinion IP – VideoJet X series – VideoJet X SN series – VIP X1600 – VG4 AutoDome IP – FlexiDome IP –Extreme IP

2.2 Forensic Search in Recordings

The functionality of IVA 4.0 is also used in searches for objects in recordings. Moving objects can be detected by their behavior (for example, direction, speed, sudden appearance or disappearance) and according to their properties (for example, size or color). You will need the Archive Player program for this. You will find the current version of the Archive Player program on the CD received when you purchased the license. To use IVA 4.0 for movement analysis in recordings, the recordings must already have been created using a device (or a camera) with IVA 4.0 settings activated accordingly.
NOTICE!
Objects can be detected both in live images and in recordings, only in the area marked as sensitive.
Install the Configuration Manager and Archive Player programs from the IVA 4.0 CD. Doing so ensures that you are using the versions that are compatible with IVA 4.0.

2.3 License

When you purchase IVA 4.0 you will be provided with an authorization number via e-mail. Using this number and the installation code that you will find in the Web browser view of the device, you can generate the activation key on the Bosch Software License Manager Internet platform. This key is then entered in the Web browser view of the device. Then you can use IVA 4.0.

Upgrade from IVA 3.5
If you have already licensed IVA 3.5 for the device, you simply need to upgrade the firmware of the device to version 4.0 or higher. The license for IVA 3.0 is then automatically changed to an IVA 4.0 license. Relicensing is not necessary. You obtain the current firmware from your customer service or from the download area on our Internet site. You can update the firmware directly via the Web browser view of the device or by using Configuration Manager. For detailed information on this process, please see the appropriate documentation.

2.4 Limitations

Please note the following considerations: IVA 4.0 is suitable for monitoring boundaries, fences and enclosures and for the protection of pipelines, overland lines, car parks etc. However, in certain environments the use of this type of motion detection system may not always be advisable; this is because movements may not always be detected or too many movements may be detected owing to reflections. Movements may be falsely detected if there is: – a reflective metal background – glass (glazed building frontages) – water as a background – cones of light moving in darkness Large areas of reflected light can also cause spurious motion detection. However, light reflections caused by falling raindrops, for example, are small enough to be ignored for statistical purposes and owing to the uniform nature of their motion. Objects that always move uniformly (such as clouds) do not impair the detection of other objects and do not trigger false alarms. A constant background is necessary in order to detect motion reliably and to assign that motion to a particular object. The more the background moves, the harder it is to distinguish moving objects from it. For instance, a person walking in front of a hedge that is moving in the wind will very probably not be detected. If the image consists to a certain extent of nothing but moving objects — in other words, if objects cannot be distinguished from each other or from the background — the motion of an individual object cannot be detected (for example, individuals in a large crowd). In this scenario, IVA 4.0 Flow can detect uniform movement flows. If a very large number of objects are detected, a lot of computing power will be required – this will reduce the power that is available for the transmission of live video data. If necessary, change the settings so that only relevant objects are detected. IVA 4.0 and the associated configuration menus offer a number of simple ways to overcome these limitations and eliminate problem areas. Note: – If you are analyzing movement in live images, the computing power of the device (sender
or camera) is challenged.
During motion analysis in recordings, the computing power of the PC, on which IVA 4.0 is
used via Archive Player, is challenged.
Bosch Security Systems Operating Manual DOC | 4.0 | 2009.06
10 en | Requirements IVA 4.0
If you are specifically looking for moving objects with certain color properties, take the following into consideration: – An object is almost never displayed in a consistent color in the image data. Pixels on the
outer edge of a detected object in particular often contain the color information of the background and not the object. Objects such as automobiles comprise a variety of parts (body, windows, tires). Each individual part of the object is displayed in a different color — the mudguards in red, for example, and the tires in black.
The color properties of an object depend upon the lighting conditions. If the lighting
conditions in a captured image change, then the captured color of the object will also change. Objects on a street appear in different hues depending on the time of day and weather conditions.
An object that changes its position or direction of movement may then appear with
different color properties. For example, automobiles are often marked on the side in color but not on the back. When people are seen from the front, the hue of the face determines the color impression; however, if the person turns around, the color properties are then defined by the hair or headdress.

IVA 4.0 Configuration | en 11

3 Configuration

IVA 4.0 and IVA 4.0 Flow are set up using the Configuration Manager program or via the Web browser view of the device. You must move the camera to the required position first in each case. When using VG4 AutoDome, the individual presets must be specified before configuring IVA 4.0 for each preset. All of the settings you make relate to the selected camera position. This means that you must reconfigure IVA 4.0 for this camera whenever you change the camera's direction or position. For more details, also refer to: Section 6 IVA and VG4 AutoDome, page 58.

3.1 Configuration with Configuration Manager

This chapter provides a description of the program, the configuration and the various IVA 4.0 settings. For details on configuring IVA 4.0 Flow, please refer to: Section 5 IVA 4.0 Flow, page 49.

4.1 The Basics

The camera 'sees' a selected area. This area is displayed in the Configuration Manager program as a single, constantly refreshed image. In the Web browser view of the device you will see a live video preview.
Objects
Objects are typically people or vehicles moving within the area seen by the camera. Objects can be filtered according to certain properties (size, aspect ratio, direction of movement, speed, location, color). An alarm event can be generated if objects match certain parameters. Objects that do not match the criteria you define are filtered out and do not generate an alarm event. It is always the center of an object that is relevant for generating an alarm event.
Sensitive Area
The scene that is captured by a camera often includes areas that are irrelevant for alarm event generation (such as sky). You can reduce the size of the area that is actually analyzed for motion. This will make motion detection for the remaining — sensitive — area correspondingly faster and more effective.
NOTICE!
Please note that when using IVA 4.0 for a forensic search in recordings, motion analysis is only possible in the area that was previously marked as the sensitive area in the recording.
Calibration
If you wish to detect objects correctly according to their size or speed, a link must be made for each camera position between the size of the real-life situation and the dimensions as they appear on the camera image. For example, you must tell the software that an object that appears on the camera image with a height of 50 pixels is around 2 m high in reality. The camera angle is used to compute object speeds. For more information, please see the description on calibration (see: Section 4.7.1 Calibration, page 39).
NOTICE!
The unit of measurement display can be adapted so that when the English language user interface is used, the relevant "imperial measurements" used in the English-speaking world are displayed (see: Section 7 Display of Units of Measurement, page 59).
Field
Fields are polygons that cover a certain area, for example an entrance or the open space in front of a barrier. These fields are created by you. Objects that move within a field can lead to the generation of an alarm event.
Line
A line can be compared to a virtual trip wire. Objects that cross a line you have defined in a pre-defined direction can trigger an alarm event.
DOC | 4.0 | 2009.06 Operating Manual Bosch Security Systems
IVA 4.0 IVA 4.0 | en 15
Route
Objects that move along a route you have defined in a pre-defined direction can trigger an alarm event. It is possible to include deviations from this route using the relevant tolerance defaults.
NOTICE!
You can create up to 16 fields, 16 lines and 8 routes (as routes are counted twice). The total sum of these items cannot be greater than 16. If this limit is reached, no additional items can be created.
Color
The color properties of an object are mainly used in forensic searches to detect moving objects by their color. As objects rarely appear in one single color, the colors are detected by analyzing the different proportions of color according to their frequency. This means that, for example, you can search for objects that consist of up to 25% dark red pixels but also include up to 20% light gray pixels at the same time. Color properties used for filtering can be adopted and refined using a marked object.
NOTICE!
The detection of color is not possible for objects that are only displayed with very few pixels.
Task
Tasks are the central control element in the IVA 4.0 setup. The aim of a task is to generate an alarm event in precisely defined situations. A task can be created using a wizard. Expert users can adapt tasks created in this way to individual requirements using additions in the script. Tasks can be activated or deactivated at any time. You can define up to eight tasks.
Wizard
To make it easier to create and edit tasks, certain tasks have wizards that guide you through the creation of a task in a few steps. During this process, you are asked to define all of the parameters required for the task.
Filter Hierarchy
IVA 4.0 offers a series of filter options so you can adapt the analysis to your requirements. You exclude certain objects or areas from the analysis in order – to avoid false alarms
and
not to increase the computing power of the device unnecessarily. Here is a schematic overview of the various options for restricting the number of alarm­triggering objects.

task, in order to define objects and their behavior so that unwanted alarm events are avoided. When setting up a task, each step represents a further filter.

4.2 Object Outlines and Other Image Information

Depending on the configuration of IVA 4.0, additional overlays in the image, for example object outlines, can provide more information. These object outlines are displayed in real time and are always synchronized exactly with the moving object. However, because the camera image on the VCA page of Configuration Manager is not live video feed, the outline does not always exactly surround the object in this case.
Description
Objects that generate an alarm event under the current settings appear on the camera image inside a red outline.
An object that has triggered one alarm event but does not generate another appears inside an orange outline (example: object has crossed a line). In the Archive Player program, an orange outline also appears around objects that will trigger an alarm event, but only if a relevant search has been carried out beforehand.
Objects that are detected as moving but do not generate an alarm event under the current settings appear inside a yellow outline.
The point at which an object is detected as idle is displayed inside a frame and marked with an i (example: abandoned bag).
The point at which an object is detected as having been removed is displayed inside a frame and marked with an X (example: theft).
A green trajectory indicates the direction in which an object has moved.

Description
A yellow flag marks the currently selected object. The properties of this object can be displayed when a task is created. An object can only be selected if you have selected the Object Properties tab (see: Section 4.8 Object Properties, page 47) or if you process the Approximation (see: Section Next Step - Approximation, page 24) step when creating a task.
A flag with a blue head marks an object that has been detected by head detection (see: Section Final Step - Define the Head Detection Conditions, page 29).
