Media Server can detect the color of vehicles identified by vehicle model recognition.
To detect the color of vehicles
Create a new configuration to send to Media Server with the process
action, or open an existing configuration that you want to modify.
In the [Session]
section, add a new analysis task by setting the EngineN
parameter. You can give the task any name, for example:
[Session] Engine0=Ingest Engine1=ANPR Engine2=VehicleModel Engine3=VehicleColor
Create a new section in the configuration file to contain the task settings and set the following parameters:
Type
|
The analysis engine to use. Set this parameter to ColorCluster . |
Input
|
The image track to process. This must be the ColorRegionWithSource output track from a vehicle recognition task. This track contains a region that can be used to analyze the vehicle's color. You can customize the selection of this region by setting the parameter ColorRegion in your vehicle recognition task, but in most cases the default value provides the greatest accuracy. |
RestrictToInputRegion
|
A Boolean value that specifies whether to analyze a region of the input image or video frame that is specified in the input record, instead of the entire image. Set this parameter to TRUE , because you want to analyze only the region that represents the vehicle, and not the entire image. |
ColorDictionary
|
(Optional but recommended) To match vehicle colors against the colors that are defined in a dictionary, specify a dictionary file. Micro Focus recommends that you use the supplied dictionary file weightedcarcolors.dat , which is optimized for analyzing color regions derived by the default ColorRegion setting in the vehicle recognition task. |
ColorThreshold
|
(Optional) Any color cluster with a score that does not meet the specified threshold is omitted from the results. |
ColorSpace
|
(Optional) The color space in which the results are provided (RGB , YCbCr , HSL , HSV , CIELAB ). |
For example:
[VehicleColor] Type=ColorCluster Input=VehicleModel.ColorRegionWithSource RestrictToInputRegion=TRUE ColorDictionary=weightedcarcolors.dat ColorThreshold=20
For more information about the parameters that customize color analysis, refer to the Media Server Reference.
Save and close the configuration file. Micro Focus recommends that you save your configuration files in the location specified by the ConfigDirectory
parameter.
