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.

Summary

Face recognition is a computer vision success story, despite the complications arising from various skin colors, orientations, facial expressions, hair colors, and lighting conditions. In this chapter, we learned the techniques for facial detection. For each of these techniques, you need to remember that facial detection requires a lot of trained images. Face detection is being widely used in many video surveillance applications, and standard APIs are available for both cloud-based and edge devices from Google, Amazon, Microsoft, and Intel, among others. We will learn about the cloud-based API in Chapter 11, Deep Learning on Edge Devices with CPU/GPU Optimization, and techniques for CNN in Chapter 4, Deep Learning on Images, and Chapter 5, Neural Network Architecture and Models. In this chapter, the CNN model for face detection and expression classification was briefly...
