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 1. Basic Image Manipulations

Since it was first released, MATLAB has been associated with technical computing and scientific programming. Due to its high uptake in academia and its large and active community, it has grown to become a versatile and multifunctional tool, providing solutions in a vast diversity of fields. Its usage in image and video processing for scientific applications has been popular for a while, but more recent versions have included processing tools that are more user-friendly and aimed at a broader spectrum of users. The usefulness of MATLAB for image processing is rather self-explanatory, since it is a programming environment specialized for matrix manipulation and images are nothing more than matrices.

In this chapter, you will be introduced to the very basics of image manipulation using MATLAB. Prior experience in using MATLAB is not required, since we will be covering everything from scratch. Some basic understanding of programming would be beneficial.

More specifically, in this chapter we will cover:

  • The basic details of the MATLAB environment and especially those that will be used extensively in this book

  • The various ways of loading, displaying, and saving an image using MATLAB

  • The most basic image manipulations that can be handled by MATLAB, that is, rotation, cropping, and resizing

So, let's get started.
