# Import a Recognizer

Micro Focus may provide recognizers that you can use with Media Server to run object class recognition. These are pre-trained, and to use one you only need to import the training data into your Media Server database. For a list of the available pre-trained recognizers, see Pre-Trained Object Class Recognizers.

To import a recognizer

1. Go to the MySupport portal and download the recognizer to your Media Server machine. When you download the recognizer, ensure the version matches the version of Media Server that you are using.

2. Import the training data by running the action `ImportObjectClassRecognizer`, for example if you downloaded the file to the folder `pretrained`, in the Media Server installation folder:

       /action=ImportObjectClassRecognizer&recognizer=roadscene
               &recognizerpath=./pretrained/roadscene.dat

   where,

   `recognizer` | The name to give to the imported recognizer.
   `recognizerpath` | The path of the recognizer data file on disk
   `recognizerdata` | The recognizer data (you can set this as an alternative to `recognizerpath`).

   Media Server imports the data. You can now run object class recognition.
