Intro to anomaly detection with OpenCV, Computer Vision, and scikit-learn

In this tutorial, you will learn how to perform anomaly/novelty detection in image datasets using OpenCV, Computer Vision, and the scikit-learn machine learning library. Imagine this — you’re fresh out of college with a degree in Computer Science. You focused your studies specifically on computer vision and machine learning. Your first job out of school […]

Multiprocessing with OpenCV and Python

In this tutorial, you will learn how to use multiprocessing with OpenCV and Python to perform feature extraction. You’ll learn how to use multiprocessing with OpenCV to parallelize feature extraction across the system bus, including all processors and cores on your computer. Today’s tutorial is inspired by PyImageSearch reader, Abigail. Abigail writes: Hey Adrian, I […]

Building an Image Hashing Search Engine with VP-Trees and OpenCV

In this tutorial, you will learn how to build a scalable image hashing search engine using OpenCV, Python, and VP-Trees. Image hashing algorithms are used to: Uniquely quantify the contents of an image using only a single integer. Find duplicate or near-duplicate images in a dataset of images based on their computed hashes. Back in […]

Creating GIFs with OpenCV

In this tutorial, you will learn how to create animated GIFs using OpenCV, Python, and ImageMagick. You’ll then combine all of these techniques to build a meme generator with OpenCV! We all need a good laugh every now and then. And perhaps the best way to find LOLs is from memes. Some of my favorite […]

pip install opencv

In this tutorial, you will learn how to pip install OpenCV on Ubuntu, macOS, and the Raspberry Pi. In previous OpenCV install tutorials I have recommended compiling from source; however, in the past year it has become possible to install OpenCV via pip, Python’s very own package manager. While installing from source will give you […]
