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 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. When…

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…

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…

In this tutorial, you will learn about contrastive loss and how it can be used to train more accurate siamese neural networks. We will implement contrastive loss using Keras and TensorFlow. Previously, I authored a three-part series on the fundamentals…

In this tutorial you will learn how to perform real-time augmented reality in video streams using OpenCV. Last week we covered the basics of augmented reality with OpenCV; however, that tutorial only focused on applying augmented reality to images. That…

In this tutorial you will learn the basics of augmented reality with OpenCV. Augmented reality takes real-world environments and then enhances these environments through computer-generated procedures that perpetually enrich the environment. Typically, this is done using some combination of visual,…

In this tutorial you will learn how to automatically determine ArUco marker type/dictionary with OpenCV and Python. Today’s tutorial is the final part of our three-part series on ArUco marker generation and detection: Generating ArUco markers with OpenCV and Python…
