Kinect in Motion – Audio and Visual Tracking by Example

Posted: 09 Sep 2013 09:13 AM PDT

Book Description

Kinect is a motion-sensing input device by Microsoft for the Xbox 360 video game console and Windows PCs. It provides capabilities to enhance human-machine interaction along with a zero-to-hero journey to engage the user in a multimodal interface dialog with your software solution.

Kinect in Motion – Audio and Visual Tracking by Example guides you in developing more than five models you can use to capture gestures, movements, and voice spoken commands. The examples and the theory discussed provide you with the knowledge to let the user become a part of your application.

Kinect in Motion – Audio and Visual Tracking by Example is a compact reference on how to master color, depth, skeleton, and audio data streams handled by Kinect for Windows.Starting with an introduction to Kinect and its characteristics, you will first be shown how to master the color data stream with no more than one page of lines of code. Learn how to manage the depth information and map them against the color ones. You will then learn how to define and manage gestures that enable the user to instruct the application simply by moving arms or any other type of natural action. Finally you will complete your journey through a multimodal interface, combining gestures with audio.The book will lead you through many detailed, real-world examples, and even guide you on how to test your application.

What you will learn from this book

  • Tune the captured color data stream to adjust the output to the environmental condition
  • Detect simple actions, such as arm movement, to raise events in your application
  • Debug and test your application to increase the quality of the software delivered
  • Track users wherever they are seated or standing so that your application can interact with the users
  • Capture sounds to convert the vocal input into application commands
  • Adjust the Kinect angle programmatically to optimize the view angle according to the user position and the environment characteristics

Approach
The book includes a series of step-by-step illustrated tutorials supported by detailed explanations for building a multimodal user interface based on Kinect for Windows.

Who this book is for
Kinect in Motion – Audio and Visual Tracking by Example is great for developers new to the Kinect for Windows SDK, and who are looking to get a good grounding in how to master video and audio tracking. It's assumed that you have some experience in C# and XAML already.

OpenCV Computer Vision with Python

Posted: 09 Sep 2013 09:07 AM PDT

Book Description

Computer Vision can reach consumers in various contexts via webcams, camera phones and gaming sensors like Kinect. OpenCV’s Python bindings can help developers meet these consumer demands for applications that capture images, change their appearance and extract information from them, in a high-level language and in a standardized data format that is interoperable with scientific libraries such as NumPy and SciPy.

“OpenCV Computer Vision with Python” is a practical, hands-on guide that covers the fundamental tasks of computer vision—capturing, filtering and analyzing images—with step-by-step instructions for writing both an application and reusable library classes.

“OpenCV Computer Vision with Python” shows you how to use the Python bindings for OpenCV. By following clear and concise examples you will develop a computer vision application that tracks faces in live video and applies special effects to them. If you have always wanted to learn which version of these bindings to use, how to integrate with cross-platform Kinect drivers and and how to efficiently process image data with NumPy and SciPy then this book is for you.

What you will learn from this book

  • Install OpenCV and related software such as Python, NumPy, SciPy, OpenNI, and SensorKinect—all on Windows, Mac or Ubuntu
  • Capture, display, and save photos and real-time videos
  • Handle window events and input events using OpenCV’s HighGui module or Pygame
  • Understand OpenCV’s image format and how to perform efficient operations on OpenCV images with NumPy and SciPy
  • Apply "curves" and other color transformations to simulate the look of old photos, movies or video games
  • Apply an effect only to edges in an image
  • Copy and resize segments of an image
  • Apply an effect only to certain depths in an image by using data from a depth sensor such as Kinect
  • Track faces, eyes, noses and mouths by using prebuilt datasets
  • Track arbitrary objects by creating original datasets

Approach
A practical, project-based tutorial for Python developers and hobbyists who want to get started with computer vision with OpenCV and Python.

Who this book is for
OpenCV Computer Vision with Python is written for Python developers who are new to computer vision and want a practical guide to teach them the essentials. Some understanding of image data (for example, pixels and color channels) would be beneficial. At a minimum you will need access to at least one webcam. Certain exercises require additional hardware like a second webcam, a Microsoft Kinect or an OpenNI-compliant depth sensor such as the Asus Xtion PRO.
