Overview of this book

Whether you want to enhance your holiday photographs or make a professional banner image for your website, you need a software tool that offers you quick and easy ways to accomplish it. All-in-one tools tend to be rare, and Matlab is one of the best available.This book is a practical guide full of step-by-step examples and exercises that will enable you to use Matlab as a powerful, complete, and versatile alternative to traditional image and video processing software.You will start off by learning the very basics of grayscale image manipulation in Matlab to master how to analyze 3-dimensional images and videos using the same tool. The methods you learn here are explained and expanded upon so that you gradually reach a more advanced level in Matlab image and video processing. You will be guided through the steps of opening, transforming, and saving images, later to be mixed with advanced masking techniques both in grayscale and in color. More advanced examples of artistic image processing are also provided, like creating panoramic photographs or HDR images. The second part of the book covers video processing techniques and guides you through the processes of creating time-lapse videos from still images, and acquiring, filtering, and saving videos in Matlab. You will learn how to use many useful functions and tools that transform Matlab from a scientific software to a powerful and complete solution for your everyday image and video processing needs.

Chapter 10. From Beginner to Expert – Handling Motion and 3-D

The methods and techniques we have presented in the previous chapters introduced you to the very basics of video processing. We did not get into the mathematical details involved in such processing and preferred to demonstrate how the theory comes into action using hands-on, practical exercises that hopefully helped you comprehend the essence of the algorithms. In this final chapter, we will try to spice things up a little, going into more complex methods that require some more mathematical insight. We will avoid going into the most difficult details, but nevertheless, this chapter may seem a little more challenging than the others, as it will demonstrate basic motion detection and estimation techniques, combine them with the notion of image registration and use them for video stabilization. Furthermore, we will indulge in the field of three-dimensional image and video processing and create our own 3-D videos.
