#003 How to resize, translate, flip and rotate an image with OpenCV?

08.05.2020

Highlight: In our previous posts we learned how to implement some simple functions that allow us to load, modify and draw some basic shapes on our input images. Now, when we have a solid foundation, it is time to dive deeper to our first image processing techniques. We should keep in mind these techniques because they are fundamental tools for almost all areas of computer vision. Therefore, a basic understanding of image processing is crucial…
