You can master Computer Vision, Deep Learning, and OpenCV - PyImageSearch
I publish a brand new Computer Vision, Deep Learning, and OpenCV tutorial every Monday at 10AM EST. Here you'll find my most recent tutorials and guides.
In this tutorial, you will learn how to split and merge channels with OpenCV. As we know, an image is represented by three components: a Red, Green, and Blue channel. And while we’ve briefly discussed grayscale and binary representations of…

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 use OpenCV and the cv2.imread function to: Load an input image from disk Determine the image’s width, height, and number of channels Display the loaded image to our screen Write the image…
Read More of OpenCV Load Image (cv2.imread)
In this tutorial, you will learn how to get and set pixel values using OpenCV and Python. You will also learn: What pixels are How the image coordinate system works in OpenCV How to access/get individual pixel values in an…
Read More of OpenCV Getting and Setting Pixels
In this tutorial, you will learn how to resize an image using OpenCV and the cv2.resize function. Scaling, or simply resizing, is the process of increasing or decreasing the size of an image in terms of width and height. A…

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 mask images using OpenCV. My previous guide discussed bitwise operations, a very common set of techniques used heavily in image processing. And as I hinted previously, we can use both bitwise operations…

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…
