# Analyze Media

Your connectors might retrieve images, audio, and video from data repositories. When these documents are processed by CFS, KeyView can extract metadata from the media but cannot process its content. To enrich documents that represent media files, you can send the media files to an IDOL Media Server. Media Server processes the files and extracts useful information.

For example, you can run optical character recognition to extract text from scanned documents, or face recognition to recognize faces in photographs. You might want to tag all images and documents that contain your company logo by running object recognition. CFS takes the information extracted by Media Server and adds it to the document's metadata or content. After this information has been added to the document, it can be used by other IDOL operations.

To set up media analysis in CFS, complete the following steps:

- Install Media Server. To run analysis on images, documents, and other media files, install Media Server 11.1 or later.

- Configure Media Server.

  - Depending on the type of analysis you want to run, you might need to train Media Server. For example, to use face recognition or object recognition, you must train Media Server to recognize specific faces or objects.
  - You must create a configuration to perform the analysis tasks that you want to run. CFS retrieves the analysis results from the ACI response, so the configuration must output data using the ACI (response) output engine. You can save this configuration on the CFS machine and configure CFS to send the configuration to Media Server, or you can save the configuration in the Media Server configurations directory, in which case CFS sends the name of the configuration to the Media Server.
- Test Media Server. HPE recommends manually sending an action to Media Server to test that your analysis tasks complete successfully.
- Configure CFS. For information about how to configure CFS, and example configurations, refer to the Connector Framework Server Administration Guide.
