In this tutorial, you will learn about adaptive thresholding and how to apply adaptive thresholding using OpenCV and the cv2.adaptiveThreshold function. Last week, we learned how to apply both basic thresholding and Otsu thresholding using the cv2.threshold function. A diverse…

In this tutorial, you will learn how to use OpenCV and the cv2.threshold function to apply basic thresholding and Otsu thresholding. A dataset for this topic enables us to understand the effect of different thresholding techniques on different types of…

Whether you’re interested in learning how to apply facial recognition to video streams, building a complete deep learning pipeline for image classification, or simply want to tinker with your Raspberry Pi and add image recognition to a hobby project, you’ll…

Today’s blog post is a followup to a tutorial I did a couple of years ago on finding the brightest spot in an image. My previous tutorial assumed there was only one bright spot in the image that you wanted…

Today’s post is a followup to a previous (extremely popular) article on detecting barcodes in images using Python and OpenCV. In the previous post we explored how to detect and find barcodes in images. But today we are going to…

UPDATE: The introduction to this post may seen a little “out there”. For some context, I had just finished watching the South Park Black Friday episodes prior to writing this post so I definitely had some inspiration regarding zombie shoppers,…

Tragic. Heartbreaking. Unbearable. These are the three words that I would use to describe my past week. About a week ago, a close childhood friend of mine passed away in a tragic car accident. I went to elementary school and…
