# Blur Images

The `Blur` transformation task blurs regions of an image or video frame. The task blurs any regions (including rectangles, polygons, and faces) that are present in the input records. It creates a new output track which contains the blurred images. This track is named `taskName.Output`, where `taskName` is the name of the transformation task. The original input track is not modified.

TIP: To write the blurred images to disk, use the image encoder.

To blur regions of images and video frames

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 task by setting the `EngineN` parameter. You can give the task any name, for example:

       [Session]
       Engine0=Ingest
       ...
       Engine3=Blur

3. Create a new configuration section to contain the task settings and set the following parameters:

   `Type` | The transformation engine to use. Set this parameter to `Blur`.
   `Input` | The name of the track that contains the images to blur, with region data. The track must supply records that contain both an image and at least one region. Any regions (including rectangles, polygons, and faces) present in an input record are blurred in the output.

   For example:

       [Blur]
       Type=Blur
       Input=FaceDetect.ResultWithSource

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