OpenCV 3.x with Python By Example - Second Edition

Summary

In this chapter, we learned how to install OpenCV-Python on various platforms. We discussed how to read, display, and save images. We talked about the importance of various color spaces, and how we can convert to multiple color spaces, splitting and merging them. We learned how to apply geometric transformations to images, and understood how to use those transformations to achieve cool geometric effects. We discussed the underlying formulation of transformation matrices, and how we can formulate different kinds of transformations based on our needs. We learned how to select control points based on the required geometric transformation. We discussed projective transformations and learned how to use image warping to achieve any given ...
