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 3. Morphological Operations and Object Analysis

In the previous chapters, you learned various image processing techniques related to image manipulation. In some of them, we concentrated our processing on specific regions of the images, predefined by the user. However, many processes that involve visual media enhancement need to focus on automatically specified regions of interest. In this chapter, we will present some basic techniques for selecting the regions of interest, based on image morphology. We will also revisit the manual selection of regions, presenting some more flexible tools. Then, you will be demonstrated some basic object analysis techniques such as edge, corner, and circle detection. Several examples will help you better understand how morphological operations combined with object analysis methods can help in targeting our processing on specific areas of an image.

In this chapter, we shall:

  • Learn about binary images and how they are used for masking

  • Learn about morphological...
