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 7. Adding Motion – From Static Images to Digital Videos

In all the previous chapters, we have focused on ways to import, manipulate, process, and save static images using MATLAB, in numerous manners and for various goals. Now, it is time to slowly indulge in the peculiarities of video processing, using MATLAB as our only tool. We will start with explaining the nature of videos and the ways they can be created. Some necessary theoretical details about videos will be explained, followed by instructions on how to load and view videos in MATLAB. Then, we will continue with ways to create video streams using static images. These are the fundamentals of time-lapse videos, so by the end of this chapter you will be able to make your first time-lapse video using MATLAB. Finally, we will provide another way to save your time-lapse sequence, which is in gif format.

In this chapter, we will learn:

  • The basic principles of digital video processing

  • The significance of frame rates

  • How we can load videos...
