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 8. Acquiring and Processing Videos

Now that you are acquainted with the processes of importing videos in MATLAB and creating new ones from still images, it is time we explore another aspect of MATLAB video processing, which is video acquisition. In this chapter, we will learn how you can use MATLAB to acquire videos, or sequences of images, which are saved on your computer rather than the storage of the camera. Furthermore, we will learn about the storage space problems faced everyday by video processing professionals and discuss compression issues and tricks, so that we mitigate this problem. Finally, some difficulties of real-time video processing in MATLAB will be presented and explained. Various tips on speeding up such processes will also be given. While learning all these, we will investigate hands-on examples that will help you comprehend various implementation techniques.

In this chapter, we will cover:

  • How we can record videos in MATLAB, using the Image Acquisition Tool

  • What...
