Building Computer Vision Projects with OpenCV 4 and C++

Creating a TensorFlow model

TensorFlow is an open source software library that focuses on high-performance numerical computation and deep learning with access and support to CPUs, GPUs, and TPUs (Tensor Process Units, new Google hardware specialized for deep learning purposes). This library is not an easy library and has a high learning curve, but the introduction of Keras (a library on top of TensorFlow) as a part of TensorFlow makes the learning curve easier, but still requires a huge learning curve itself. 

In this chapter, we cannot explain how to use TensorFlow because we will require a separate book for this topic alone, but we are going to explain the structure of the CNN we are going to use. We will show how to use an online visual ...
