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.

Training an object detector in the AWS SageMaker cloud platform

AWS (https://aws.amazon.com) is the Amazon cloud platform used to perform a wide variety of tasks in the cloud. AWS SageMaker is the machine learning platform used to train and deploy models using the AWS interactive platform. AWS SageMaker interacts with AWS S3 buckets to store and retrieve data. The step-by-step process of training an object detector is described in the following section.

Setting up an AWS account, billing, and limits

Increase the service limit to ml.p3.2xlarge or something similar by contacting AWS Support. Note that it may take up to two business days for the instance type to get approved, so plan accordingly. If this is not done, then you...
