Configure Person Analysis

This section describes how to run person analysis.

TIP: You must first detect people by running face detection or object class recognition with the pre-trained person recognizer.

To configure person analysis

  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 [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=FaceDetect
    Engine2=PersonAnalysis
  3. Create a new configuration section to contain the task settings and set the following parameters:

    Type The analysis engine to use. Set this parameter to PersonAnalysis.
    Input The track to analyze. This track must contain records that identify people. You can use the output from face detection (or another face analysis task such as face recognition) or the output from an object class recognition task that uses the pre-trained person recognizer.
    ClassificationTypes A comma-separated list of strings that specify which classifications to perform.
    NumParallel The maximum number of video frames to analyze simultaneously.

    For example:

    [PersonAnalysis]
    Type=PersonAnalysis
    Input=FaceDetect.DataWithSource
    ClassificationTypes=clothing,hatandhair
    NumParallel=4
  4. Save and close the configuration file. OpenText recommends that you save your configuration files in the location specified by the ConfigDirectory parameter.
