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 5. 2-Dimensional Image Filtering

Up to this point, you should be able to use MATLAB at a novice level, to perform various useful image processing operations. It is now time to move on to more advanced image filtering processes and revisit some of the already covered ones. In this chapter, we will dig a little deeper into the image filtering theory and use some more complicated techniques to enhance our images. We will also provide some more information about the processes that you have already learned, so that you take a look behind the curtains and see what they really do. All the methods we will present, will once more be accompanied by hands-on examples that demonstrate their significance in both typical and more advanced image processing tasks.

In this chapter, we shall learn:

  • The basic theory on image filtering and processing pixel neighborhoods

  • How we can filter an image using convolution

  • Alternative ways to filter an image

  • Creating image filters in MATLAB

  • Using filters for image...
