Identify Vehicle Colors

Media Server can detect the color of vehicles identified by vehicle model detection.

To detect the color of vehicles

  1. Create a new configuration to send to Media Server with the process action, or open an existing configuration that you want to modify.

  2. In the [Analysis] section, add a new analysis task by setting the AnalysisEngineN parameter. You can give the task any name, for example:

    [Analysis]
    AnalysisEngine0=ANPR
    AnalysisEngine1=VehicleModel
    AnalysisEngine2=VehicleColor
  3. 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 track must be the ColorRegionWithSource output track from a vehicle model analysis task. This track contains a region identified by the vehicle model task, which should contain a sample of the vehicle's color. You can customize the selection of this region by setting the parameter ColorRegion in your vehicle model analysis task.
    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 the color analysis task to analyze only the region that represents the vehicle, and not the entire image.
    ColorDictionary (Optional) To match vehicle colors against the colors that are defined in a dictionary, specify the path to a dictionary file.
    ColorThreshold (Optional) The analysis task discards colors that do not make up a significant proportion of the region (as specified by this parameter).
    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=./colorcluster/carcolors.dat
    ColorThreshold=20
    ColorSpace=HSV

    For more information about the parameters that customize color analysis, refer to the Media Server Reference.

  4. Save and close the configuration file. HPE recommends that you save your configuration files in the location specified by the ConfigDirectory parameter.
