Overview of this book

<p>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 how to efficiently process image data with NumPy and SciPy, then this book is for you.</p> <p>This book has practical, project-based tutorials for Python developers and hobbyists who want to get started with computer vision with OpenCV and Python. It is a 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.</p>

Appendix B. Generating Haar Cascades for Custom Targets

This appendix shows how to generate Haar cascade XML files like the ones used in Chapter 4, Tracking Faces with Haar Cascades. By generating our own cascade files, we can potentially track any pattern or object, not just faces. However, good results might not come quickly. We must carefully gather images, configure script parameters, perform real-world tests, and iterate. A lot of human time and processing time might be involved.
