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.

The editor


A very important tool in MATLAB, besides the default ones you see when first opening the environment, is the editor. The editor can be invoked in various ways, depending on what you want to accomplish. The three basic ways are:

  • Click on the New Script icon on the HOME tab

  • Click on the New icon on the HOME tab and then click on either one of the first four choices: Script, Function, Example, or Class

  • Click on the Open icon on the HOME tab and then either search for a file in your computer with a .m extension (MATLAB code) by clicking on Open…, or selecting a file from the RECENT FILES list

The EDITOR window

Once you have invoked the editor using any of the ways mentioned previously, a new window will pop up. In this window, you can write, alter, and save your code using a powerful code editor. We will not go into detail here, since to fully comprehend the functionalities of this tool, we first have to learn how to write code in MATLAB.
