Being able to efficiently extract and transform data for the training of complex applications is primordial, but this is assuming that enough data is available for such tasks in the first place. After all, NNs are data-hungry methods and even though we are in the big data era, large enough datasets are still tenuous to gather and even more difficult to annotate. It can take several minutes to annotate a single image (for instance, to create the ground truth label map for semantic segmentation models), and some annotations may have to be validated/corrected by experts (for instance, when labeling medical pictures). In some cases, images themselves may not be easily available. For instance, it would be too time- and money-consuming to take pictures of every manufactured object and their components when building automation models for industrial plants...

Overview of this book
Computer vision solutions are becoming increasingly common, making their way into fields such as health, automobile, social media, and robotics. This book will help you explore TensorFlow 2, the brand new version of Google's open source framework for machine learning. You will understand how to benefit from using convolutional neural networks (CNNs) for visual tasks.
Hands-On Computer Vision with TensorFlow 2 starts with the fundamentals of computer vision and deep learning, teaching you how to build a neural network from scratch. You will discover the features that have made TensorFlow the most widely used AI library, along with its intuitive Keras interface. You'll then move on to building, training, and deploying CNNs efficiently. Complete with concrete code examples, the book demonstrates how to classify images with modern solutions, such as Inception and ResNet, and extract specific content using You Only Look Once (YOLO), Mask R-CNN, and U-Net. You will also build generative adversarial networks (GANs) and variational autoencoders (VAEs) to create and edit images, and long short-term memory networks (LSTMs) to analyze videos. In the process, you will acquire advanced insights into transfer learning, data augmentation, domain adaptation, and mobile and web deployment, among other key concepts.
By the end of the book, you will have both the theoretical understanding and practical skills to solve advanced computer vision problems with TensorFlow 2.0.
