What is this book? And what does it to cover?
Deep Learning for Computer Vision with Python will make you an expert in deep learning for computer vision and visual recognition tasks.
Inside the book we will focus on:
- Neural Networks and Machine Learning
- Convolutional Neural Networks (CNNs)
- Object detection/localization with deep learning
- Training large-scale (ImageNet-level) networks
- Hands on implementations using the Python programming language and the Keras (which is compatible with either TensorFlow or Theano) + mxnet libraries
After going through Deep Learning for Computer Vision with Python, you'll be able to solve real-world problems with deep learning.
Utilize Python, Keras (with either a TensorFlow or Theano backend), and mxnet to build deep learning networks.
Python, Keras, and mxnet are all well-built tools that, when combined, create a powerful deep learning development environment that you can use to master deep learning for computer vision and visual recognition.
We'll be utilizing the Python programming language for all examples in this book. Python is an easy language to learn and is hands-down the best way to work with deep learning algorithms.
To build and train our deep learning networks we'll primarily be using the Keras library. Keras supports both TensorFlow and Theano, making it super easy to build and train networks quickly.
We'll also use mxnet, a deep learning library that specializes in distributed, multi-machine learning. The ability to parallelize training across GPUs/devices is critical when training deep neural network architectures on massive datasets (such as ImageNet).
Each library that we use in this book will be thoroughly reviewed to ensure you understand how to build & train your own deep learning networks.
Dr. Rosebrock delivers on what he promises! [Inside the book] he focuses on mastering deep learning concepts, lays down the theoretical foundation, develops interesting deep learning and computer vision projects with detailed explanation of Python scripts, and puts to your disposal priceless expertise to get you quickly engaged in the incredible field of deep learning.

A three volume book — customized to what you want to learn.
Since this book covers a huge amount of content, I've decided to break the book down into three volumes called "bundles". A bundle includes the eBook, video tutorials, and source code for a given volume.
Each bundle builds on top of the others and includes all content from the lower volumes. You should choose a bundle based on: (1) how in-depth you want to study deep learning, computer vision, and visual recognition and (2) your particular budget.
You can find a quick breakdown of the three bundles below — the full list of topics to be covered can be found later on this page:
- Starter Bundle: A great fit for those taking their first steps towards deep learning for image classification mastery. You'll learn the basics of (1) machine learning, (2) neural networks, (3) Convolutional Neural Networks, and (4) how to work with your own custom datasets.
- Practitioner Bundle: Perfect for readers who are ready to study deep learning in-depth, understand advanced techniques, and discover common best practices and rules of thumb.
- ImageNet Bundle: The complete deep learning for computer vision experience. In this bundle, I demonstrate how to train large-scale neural networks on the massive ImageNet dataset. You just can't beat this bundle if you want to master deep learning for computer vision.
More than just a book — this is your gateway to mastering deep learning.
Deep Learning for Computer Vision with Python is more than just a book. It's a complete package that is designed from the ground-up to help you master deep learning.
Each bundle includes:
- The eBook files in PDF, .mobi, and .epub format.
- Video tutorials and walkthroughs for each chapter in the book.
- All source code listings so you can run the examples from the book out-of-the-box.
- A downloadable pre-configured Ubuntu VirtualBox virtual machine that ships with all necessary Python + deep learning libraries you will need to be successful pre-installed.
- Access to the Deep Learning for Computer Vision with Python companion website, so you can further your knowledge, even when you're done reading the book.
The ImageNet Bundle also includes a hardcopy edition of the complete book delivered to your doorstep.
New to machine learning and neural networks? Go with the Starter Bundle.
The Starter Bundle begins with a gentle introduction to the world of computer vision and machine learning, builds to neural networks, and then turns full steam into deep learning and Convolutional Neural Networks. You'll even solve fun and interesting real-world problems using deep learning along the way.
The Starter Bundle is appropriate if:
- You are new to the world of machine learning/neural networks.
- You are on a budget.
While this is the lowest tier bundle, you'll still be getting a complete education. That said, for a more in-depth treatment of deep learning for computer vision, I would recommend either the Practitioner Bundle or ImageNet Bundle.
Want an in-depth treatment of deep learning? Choose the Practitioner Bundle.
The Practitioner Bundle is appropriate if you want to take a deeper dive in deep learning. Inside this bundle, I cover more advanced techniques and best practices/rules of thumb. When you factor in the cost/time of training these deeper networks, the techniques I cover in the Practitioner Bundle will save you so much time that the bundle will pay for itself, guaranteed.
While the Starter Bundle focuses on learning the fundamentals of deep learning, the Practitioner Bundle takes the next logical step and covers more advanced techniques, including transfer learning, fine-tuning, networks as feature extractors, working with HDF5 + large datasets, and object detection and localization.
I also review Deep Dreaming and Neural Style, Generative Adversarial Networks (GANs), and Image Super Resolution in detail.
Using the techniques discussed in this bundle, you'll be able to compete in image classification competitions such as the Kaggle Dog vs. Cats Challenge (claiming a position in the top-25 leaderboard) and Stanford's cs231n Tiny ImageNet challenge.
This bundle is perfect for you if you are ready to study deep learning in-depth, understand advanced techniques, and discover common best practices and rules of thumb.
The Practitioner Bundle gives you the best bang for your buck. If you're even remotely serious about studying deep learning, you should go with this bundle.
Interested in a complete deep learning education? Go with the ImageNet Bundle.
The ImageNet Bundle is the most in-depth bundle and is a perfect fit if you want to train large-scale deep neural networks. This is also the only bundle that includes a hardcopy edition of the complete Deep Learning for Computer Vision with Python book, mailed to your doorstep.
Inside this bundle, I demonstrate how to build a custom Python framework to train network architectures from scratch — this is the exact same framework I use when training my own neural networks. We'll use this framework to train AlexNet, VGGNet, SqueezeNet, GoogLeNet, and ResNet on the challenging ImageNet dataset.
Using the training techniques I outline in this bundle, you'll be able to reproduce the results you see in popular deep learning papers and publications — this is an absolute must for anyone doing research and development in the deep learning space.
To demonstrate advanced deep learning techniques in action, I provide a number of case studies, including age + gender recognition, emotion and facial expression recognition, car make + model recognition, and automatic image orientation correction.
This bundle also includes a special BONUS GUIDE that reviews Faster R-CNNs and Single Shot Detectors (SSDs) and how to use them.
You should choose the ImageNet Bundle if:
- You want the complete deep learning for computer vision experience.
- Intend on training deep neural networks on large datasets from scratch.
When it comes to studying deep learning, you can't beat this bundle!

Which bundle should I buy?
Each bundle builds on top of the others and includes all content from lower volumes. You should choose a bundle based on (1) how in depth you want to study deep learning, computer vision & visual recognition and (2) your particular budget. Use the "Here's the full breakdown of what you'll learn inside Deep Learning for Computer Vision with Python" section above to help you decide which topics you want to learn, then pick a bundle based on your choices.
What happens after I purchase?
After you purchase your copy of Deep Learning for Computer Vision with Python you will (1) receive an email receipt for your purchase and (2) you will be able to download your books, code, datasets, etc. immediately. If you purchased the ImageNet Bundle, the only bundle to include a hardcopy edition, you will receive a second email to enter your shipping information.
Your book is more expensive than other online courses and books — why is your book worth the price?
First, it's important to understand that Deep Learning for Computer Vision with Python is the most complete, comprehensive deep learning education online (the ImageNet Bundle is over 900+ pages). Not only does it cover the theory behind deep learning, it also details the implementation as well. You can't find a book this detailed in any other online platform, MOOC, or book.
Secondly, I personally dedicate time daily to answering your questions, providing help, and offering suggestions — no other book or course online gives you this level of access to authors. To be totally honest with you, I've considered raising the price of this book multiple times but haven't (yet).
My book may seem expensive, but the value you are getting is multiple orders of magnitude higher than any other book or course. I encourage you to give my book a try. Once you dig into the content I'm confident you'll agree that the book is well worth the price.
Why are we using the Python programming language?
First of all, Python is awesome. It is an easy language to learn and hands-down the best way to work with deep learning algorithms. The simple, intuitive syntax allows you to focus on learning the basics of deep learning, rather than spending hours fixing crazy compiler errors in other languages.
What deep learning libraries and packages are we using?
We will be using the Keras and mxnet libraries in this book. Keras supports both TensorFlow and Theano, making it super easy to quickly build and train networks. We primarily use the TensorFlow backend in this book. The mxnet library specializes in distributed learning, making it a great choice for training deep network architectures on massive datasets. Each library in the book is thoroughly reviewed to ensure you understand how to build & train your own deep learning networks.
I want to learn TensorFlow. Is TensorFlow covered?
This book primarily uses Keras and mxnet. We use TensorFlow as the computation engine for Keras. Think of Keras as a wrapper around TensorFlow making it easier (and faster) to build and train deep neural networks. Together, Keras and TensorFlow are the two most widely used deep learning libraries. As a deep learning expert who has taught thousands of students, I recommend you master Keras before TensorFlow. In 99.9% of situations, Keras will (1) be easier to use and (2) obtain the same (if not better) accuracy as TensorFlow.
What if I'm a beginner at deep learning?
Don't worry; you won't get bogged down by tons of theory and complex equations. We'll start off with the basics of machine learning and neural networks. You'll learn in a fun, practical way with lots of code. You'll be a neural network ninja in no time, and be able to graduate to the more advanced content.
What if I'm already experienced in deep learning?
This book isn't just for beginners — there's advanced content in here too. You'll discover how to train your own custom object detectors using deep learning. You'll build a custom framework that can be used to train very deep architectures on the challenging ImageNet dataset from scratch. I'll even show you my personal blueprint that I use to determine which deep learning techniques to apply when confronted with a new problem. Best of all, these solutions and tactics can be directly applied to your current job, research, and projects.
Do I need any programming experience before reading this book?
This book assumes you have some prior programming experience (e.g. you know what a variable, function, loop, etc. are). You should have more skills than a novice, but certainly not an intermediate or advanced developer. As long as you understand basic programming logic flow you'll be successful in reading (and understanding) the contents of this book.
Do I need to know OpenCV?
You do not need to know the OpenCV library to be successful when going through this book. We only use OpenCV to facilitate basic image processing operations such as loading an image from disk, displaying it to our screen, and a few other basic operations. That said, a little bit of OpenCV experience goes a long way, so if you're new to OpenCV I highly recommend (1) purchase a copy of Deep Learning for Computer Vision with Python and (2) work through my other book, Practical Python and OpenCV to learn the fundamentals.
Do I need any special hardware to run the examples in the Starter Bundle or Practitioner Bundle?
All examples inside the Starter Bundle can be executed on a CPU without a problem. The same is true for most examples in the Practitioner Bundle, although some examples will take longer to run. In either case, a GPU will dramatically speed up the network training process but is not a requirement.
Do I need special hardware for the ImageNet Bundle?
If you intend on going with the ImageNet Bundle, you are expected to have a GPU with at least 6GB of memory. The more GPUs you have available, the better. You should also have at least 1TB of free space on your machine. The ImageNet Bundle covers very advanced deep learning techniques on massive datasets, so make sure you make the necessary hardware preparations.
Can I upgrade from a lower tier bundle to a higher one? How does the upgrade process work?
Yes, you can always upgrade your bundle to a higher one. For example, you could purchase the Starter Bundle and then upgrade to the Practitioner Bundle or ImageNet Bundle at a later date.
The cost to upgrade would simply be the price difference between your current bundle and the bundle you wanted to upgrade to (you would not need to "repurchase" the content you already own). To upgrade your bundle just send me an email and I can get you the upgrade link.
What GPUs do you recommend for the book?
I personally use the NVIDIA Titan X (12GB) on a daily basis for training my own deep learning networks. The Titan X a bit expensive, so NVIDIA has released the GTX 1080 with 8GB of memory for half the cost of the Titan X. The latest addition to the NVIDIA family, the 1080 Ti (11GB), is also highly recommended. Alternatively, I would recommend using Amazon EC2 and their GPU instances (particularly p2.* and g2.*) in the cloud to train your networks if you do not want to purchase physical hardware.
Can I use the cloud for deep learning?
Yes, you can absolutely use cloud services such as Amazon Web Services (AWS) or Microsoft Azure either with or without a GPU to work through the examples in this book. To jumpstart your education, I have released my own personal pre-configured Amazon Machine Instance (AMI) to help you with your studies and projects. Simply launch an EC2 instance using this pre-configured AMI and you'll be ready to train your own deep neural networks in the matter of minutes! If you're a Microsoft Azure user, you can spin up Microsft DSVM instance and be up and running in a few minutes as well.
Are the hardcopy editions shipping?
Yep, the hardcopies are indeed shipping! The ImageNet Bundle is the only bundle that includes a hardcopy edition. After you purchase, you will receive an email with a link to enter your shipping information. Once I have your shipping address I can get your hardcopy edition in the mail, normally within 48 hours.
When will the video tutorials be released?
All video tutorials have been released! You will be able to download the videos as soon as you purchase your copy.
Where can I learn more about you?
I have authored over 250+ blog posts about computer vision, OpenCV, and deep learning over at PyImageSearch.com. Check out the posts to get a feel for my teaching and writing style (not to mention the quality and depth of the tutorials). I would also highly suggest that you sign up for the (free) Table of Contents and sample chapters I am offering using the form at the bottom-right corner of this page.
I have another question.
