# Set up a Task to Generate Image Hashes

To generate image hashes

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=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 to generate image hashes from.
   `Region` | (Optional) To create a hash from a region of the image, instead of the entire image, specify the region.
   `RegionUnit` | (Optional) The units used to specify the position and size of the region of interest (`pixel` or `percent`).

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