Chapter 1. Applying Geometric Transformations to Images
In this chapter, we are going to learn how to apply cool geometric effects to images. Before we get started, we need to install OpenCV-Python. We will discuss how to install the necessary tools and packages as well.
By the end of this chapter, you will know:
- How to install OpenCV-Python
- How to read, display, and save images
- How to convert between multiple color spaces
- How to apply geometric transformations like translation, rotation, and scaling
- How to use affine and projective transformations to apply funny geometric effects on photos
Installing OpenCV-Python
Let's see how to install OpenCV with Python support on multiple platforms.
