Summary

In this chapter, we started by understanding the various geometric transforms and their matrix representations. We also saw how we can use OpenCV's functions to carry out these transformations. Then, we performed arithmetic operations on images and saw how addition and multiplication with a constant can be understood as a brightening operation. Next, we discussed binary images and how they can be obtained using binary thresholding. Then, we discussed bitwise operations and how they can be carried out using OpenCV. Finally, we had a look at the concept of masking, where we used NumPy to obtain interesting results.

In the next chapter, we will jump into the world of histograms and discuss how we can use histogram matching and histogram equalization as more advanced image processing steps.
