You can master Computer Vision, Deep Learning, and OpenCV - PyImageSearch
OpenCV TutorialsLearn how to successfully use, operate, and apply the OpenCV library for Computer Vision and Deep Learning using these free OpenCV tutorials and guides.
In this tutorial, you will learn how to rotate an image using OpenCV. Additionally, I’ll also show you how to rotate an image using my two convenience functions from the imutils library, imutils.rotate and imutils.rotate_bound, which make rotating images with…

In this tutorial, you will learn how to flip images using OpenCV and the cv2.flip function. Similar to image rotation, OpenCV also provides methods to flip an image across its x- or y-axis. Though flipping operations are used less often,…

In this tutorial, you will learn how to apply bitwise AND, OR, XOR, and NOT with OpenCV. In our previous tutorial on Cropping with OpenCV, you learned how to crop and extract a Region of Interest (ROI) from an image.…

In this tutorial, you will learn how to perform image arithmetic (addition and subtraction) with OpenCV. Remember way, way back when you studied how to add and subtract numbers in grade school? Well, it turns out, performing arithmetic with images…

In this tutorial, you will learn how to crop images using OpenCV. As the name suggests, cropping is the act of selecting and extracting the Region of Interest (or simply, ROI) and is the part of the image in which…
