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 explain how to compile and install the necessary libraries to follow every example in this book.
By the end of this chapter, you will know:
- How to install OpenCV-Python
- How to read, display, and save images
- How to convert to multiple color spaces
- How to apply geometric transformations such as translation, rotation, and scaling
- How to use affine and projective transformations to apply funny geometric effects to photos
