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.

Summary


This chapter was a quick dive into the ways that MATLAB can replace your everyday image editing tool, while giving you extra parameterization choices that you wouldn't have in basic software. More specifically, you have learned the basic ways to:

  • Load and display an image in MATLAB using the command line

  • Load, display, manipulate, and save an image using imtool

  • Rotate, flip, or mirror an image in the command line

  • Crop and resize an image using functions

  • Save an image in a variety of formats

These processes are core functionalities of everyday image manipulation for every amateur photographer. They provide the foundations for any complex image processing task and will be used throughout the book. So, congratulations! You have set the first stepping stone to climb to more sophisticated image processing tasks. The rest of the chapters will guide you through some more complex image processing that MATLAB offers and will then move on to video processing. Depending on your needs, you will either be able to use it as a quick reference for any of the techniques it covers, or you can read through the chapters in a sequential order, as you would do in a Media Processing course.

The next chapter will introduce you to different ways to work with grayscale image pixels and manipulate their values. On finishing it, you will be able to enhance and improve the visual quality of an image. Have fun!
