Chapter 2. Working with Pixels In Grayscale Images
Now you have grasped some basic visual media processes that MATLAB has to offer. You have learned how to import and export images, apply basic geometric transformations on them, and generally perform tasks that are included in most basic image editors. In this chapter, you will start building up your MATLAB skills by taking advantage of ready-made functions that allow editing of pixel values in an image. You will also start making your own small programs, save them as scripts or functions, and apply them in practical examples.
In this chapter, we will cover:
- How to manipulate one or more pixels in an image using
for loops, or indexing - How to perform histogram-based processing using MATLAB
- How to write our first scripts and functions for automating more complex processes
So, let's get started!
