2. Common Operations When Working with Images

Overview

In this chapter, we will take a look at geometric transformations – rotation, translation, scaling, affine transformation, and perspective transformation. We will crop im ages using NumPy and OpenCV functions. Then, we will discuss binary images and how to carry out arithmetic operations on images. We will have a look at some real-life applications where these techniques can come in handy.

By the end of this chapter, you should have a fairly good idea of how to process images for your specific case study. You will be able to use affine transformations on images and carry out tasks such as motion identification using binary operations.
