# Identify Duplicate Images

To identify duplicate images

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=ImageHash

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 `ImageHash`.
   `Input` | (Optional) The name of the track that contains the images to analyze.
   `Database` | (Optional) The image hash database to use to identify duplicate images. If you do not set this parameter, Media Server uses all image hash databases.
   `MatchThreshold` | (Optional) The minimum confidence score required for a match.

   For example:

       [ImageHash]
       Type=ImageHash
       Database=MyImageHashes
       MatchThreshold=60

   For a complete list of parameters you can use to customize this task, refer to the Media Server Reference.

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