Compressive Imaging: Structure, Sampling, Learning

Cambridge University Press (to appear)


This book presents an in-depth treatment of compressive imaging, a topic which has developed over the last decade and has fundamentally changed the way modern image reconstruction is performed. It commences with a practical introduction to the subject, supported with examples and downloadable code. Next, it introduces core mathematical techniques in a concise yet rigorous way, before providing a detailed treatment of the mathematics of compressive imaging. The final part is devoted to the most recent trends in compressive imaging, deep learning and neural networks. This highly timely component of the book provides the first readable overview of this nascent topic. Looking toward the next 10-20 years of imaging research, and using both empirical and mathematical insights, this book examines both the potential benefits and the pitfalls of these latest approaches.


This book will soon be published by Cambridge University Press. In the meantime, selected materials are available for viewing.
