Overview of this book

Computer vision allows machines to gain human-level understanding to visualize, process, and analyze images and videos. This book focuses on using TensorFlow to help you learn advanced computer vision tasks such as image acquisition, processing, and analysis. You'll start with the key principles of computer vision and deep learning to build a solid foundation, before covering neural network architectures and understanding how they work rather than using them as a black box. Next, you'll explore architectures such as VGG, ResNet, Inception, R-CNN, SSD, YOLO, and MobileNet. As you advance, you'll learn to use visual search methods using transfer learning. You'll also cover advanced computer vision concepts such as semantic segmentation, image inpainting with GAN's, object tracking, video segmentation, and action recognition. Later, the book focuses on how machine learning and deep learning concepts can be used to perform tasks such as edge detection and face recognition. You'll then discover how to develop powerful neural network models on your PC and on various cloud platforms. Finally, you'll learn to perform model optimization methods to deploy models on edge devices for real-time inference. By the end of this book, you'll have a solid understanding of computer vision and be able to confidently develop models to automate tasks.

An introduction to Darknet for object detection

Darknet is an open neural network framework that is written in C and managed by Joseph Redmon, the first author of YOLO. Detailed information about Darknet can be found at pjreddie.com. In this section, we will discuss Darknet and Tiny Darknet for object detection.

Detecting objects using Darknet

In this section, we will install Darknet from the official Darknet site and use it for object detection. Follow these steps to install Darknet on your PC and make an inference:

  1. The following five lines should be entered in the terminal. Hit Enter after each command line. These steps will clone Darknet from GitHub, which will create a Darknet directory in your PC as well as get the...
