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.
A few weeks ago, I demonstrated how to order the (x, y)-coordinates of a rotated bounding box in a clockwise fashion — an extremely useful skill that is critical in many computer vision applications, including (but not limited to) perspective…

We have now reached the final installment in our three part series on measuring the size of objects in an image and computing the distance between objects. Two weeks ago, we started this round of tutorials by learning how to…

Last updated on July 8, 2021. Measuring the size of an object (or objects) in an image has been a heavily requested tutorial on the PyImageSearch blog for some time now — and it feels great to get this post…

In today’s blog post, I interview PyImageSearch Gurus member, Tuomo Hiippala, who was recently awarded a 28000€ grant (approximately $30,500 USD) to research how computer vision can be used to study visual culture, including social media images and photo archives.…

One of my favorite aspects of running the PyImageSearch blog is sharing little bitesize OpenCV tips and tricks that I’ve learned after nearly 7 years of using the OpenCV library. Today’s tip comes from my bag of experiences: constructing transparent…

Last week’s blog post taught us how to write videos to file using OpenCV and Python. This is a great skill to have, but it also raises the question: How do I write video clips containing interesting events to file…

Let me just start this blog post by saying that writing to video with OpenCV can be a huge pain in the ass. My intention with this tutorial is to help you get started writing videos to file with OpenCV…
