Computer Vision and TensorFlow Fundamentals

Computer vision is rapidly expanding in many different applications as traditional techniques, such as image thresholding, filtering, and edge detection, have been augmented by deep learning methods. TensorFlow is a widely used, powerful machine learning tool created by Google. It has user configurable APIs available to train and build complex neural network model in your local PC or in the cloud and optimize and deploy at scale in edge devices.

In this chapter, you will gain an understanding of advanced computer vision concepts using TensorFlow. This chapter discusses the foundational concepts of computer vision and TensorFlow to prepare you for the later, more advanced chapters of this book. We will look at how to perform image hashing and filtering. Then, we will learn about various methods of feature extraction and image retrieval...

Description

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.

Good variety of examples to work through. The examples and concepts go beyond the typical introductory book. The code is generic enough to run locally or on AWS SageMaker. The author provides great support when problems were encountered. I'm glad I purchased this book.Would love to see another advanced book that covers TensorFlow model zoo, model/research, object detection API, TensorRT and deploying models to IoT edge devices (e.g. NVIDIA Jetsons)

This book is a good starting point for computer science professionals who are new to the field of Computer Vision. I personally have not worked with CV a lot, but have the general prerequisite knowledge of machine learning concepts, and found this book to be a good starting point. This book had a good balance between theoretical concepts and working code snippets that can be tried out. The GitHub repo linked in the book was very helpful to replicate the code snippets as well, and I have not come across many books with this kind of functionality. All the code snippets I tried out worked well without any problems. From a practical implementation point of view, the section on deploying the model on a phone was quite interesting and fun to explore. Each concept mentioned in the book was very well illustrated and supported with thorough mathematical explanations as well.On the downside, I felt the book was focused mostly on image applications and could have also included more applications with videos as input in addition to images. I would have also liked a little more intuition when explaining certain concepts, in addition to the mathematical formulations already mentioned in the book. That really helps readers grasp the concept well.Overall, this was a well-written and instructive book for people wanting to gain knowledge in the CV domain!

There are many books out there / but this book stands out - very clear explanation of codes and contents, lots of detailed explanations for object detection, classification, visual search, matching and training in cloud. All the codes work and and their screen video has been really helpful. I find deployment of model in phone and Raspberry PI example has many practical usage. +4minus point: some sections like action recognition and semantic segmentation could be expanded more with training a custom model. -1bonus point: the author has been very helpful to connect and answer questions through LinkedIn +1

Says it teaches image in painting but the linked notebook is just a GAN to generate MNIST digits
