In the first chapter, we discussed various new additions in the OpenCV 4.0 release. One of the key releases to note is the OpenVINO toolkit. It's also interesting to note that the OpenVINO toolkit was selected as the 2019 Developer Tool of the Year by Embedded Vision Alliance.

In this chapter, we will focus only on how to use the OpenVINO toolkit with OpenCV. We will begin by installing the OpenVINO toolkit and then proceed to an interactive face detection demo with it. We will also learn to use OpenVINO Model Zoo with OpenCV and the OpenVINO Inference Engine (IE) with OpenCV. At the end of this chapter, we will also learn how to carry out image classification using OpenCV with OpenVINO IE.

In this chapter, we will cover the following topics:

• OpenVINO toolkit installation
• Interactive face detection demo
• Using OpenVINO Model Zoo with OpenCV
• Using OpenVINO IE with OpenCV
• Image classification using OpenCV with OpenVINO IE
