Who This Book Is For
If you are an Android developer and want to know how to implement vision-aware applications using OpenCV, then this book is definitely for you.
It would be very helpful if you understand the basics of image processing and computer vision, but no prior experience is required
What You Will Learn
Identify and install all the elements needed to start building vision-aware Android applications
Explore image representation, colored and gray scale
Recognize and apply convolution operations and filtering to deal with noisy data
Use different shape analysis techniques
Extract and identify interest points in an image
Understand and perform object detection
Run native computer vision algorithms and gain performance boosts
In Detail
Starting from the basics of computer vision and OpenCV, we'll take you all the way to creating exciting applications. You will discover that, though computer vision is a challenging subject, the ideas and algorithms used are simple and intuitive, and you will appreciate the abstraction layer that OpenCV uses to do the heavy lifting for you. Packed with many examples, the book will help you understand the main data structures used within OpenCV, and how you can use them to gain performance boosts. Next we will discuss and use several image processing algorithms such as histogram equalization, filters, and color space conversion. You then will learn about image gradients and how they are used in many shape analysis techniques such as edge detection, Hough Line Transform, and Hough Circle Transform. In addition to using shape analysis to find things in images, you will learn how to describe objects in images in a more robust way using different feature detectors and descriptors.
By the end of this book, you will be able to make intelligent decisions using the famous Adaboost learning algorithm.
Style and approach
An easy-to-follow tutorial packed with hands-on examples. Each topic is explained and placed in context, and the book supplies full details of the concepts used for added proficiency.
