+Check [a wiki](https://github.com/opencv/opencv/wiki/Deep-Learning-in-OpenCV) for a list of tested models.
+
+If OpenCV is built with [Intel's Inference Engine support](https://github.com/opencv/opencv/wiki/Intel%27s-Deep-Learning-Inference-Engine-backend) you can use [Intel's pre-trained](https://github.com/opencv/open_model_zoo) models.
+
+There are different preprocessing parameters such mean subtraction or scale factors for different models.
+You may check the most popular models and their parameters at [models.yml](https://github.com/opencv/opencv/blob/master/samples/dnn/models.yml) configuration file. It might be also used for aliasing samples parameters. In example,
+
+```bash
+python object_detection.py opencv_fd --model /path/to/caffemodel --config /path/to/prototxt
+```
+
+Check `-h` option to know which values are used by default:
+
+```bash
+python object_detection.py opencv_fd -h
+```
