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…

This is the final post in our three part series on shape detection and analysis. Previously, we learned how to: Compute the center of a contour Perform shape detection & identification Today we are going to perform both shape detection…

Last updated on July 7, 2021. This tutorial is the second post in our three-part series on shape detection and analysis. Last week we learned how to compute the center of a contour using OpenCV. Today, we are going to…

Today, we are going to start a new 3-part series of tutorials on shape detection and analysis. Throughout this series, we’ll learn how to: Compute the center of a contour/shape region. Recognize various shapes, such as circles, squares, rectangles, triangles,…

One of my favorite parts of running the PyImageSearch blog is a being able to link together previous blog posts and create a solution to a particular problem — in this case, real-time panorama and image stitching with Python and…

I’ll keep the introduction to today’s post short, since I think the title of this post and GIF animation above speak for themselves. Inside this post, I’ll demonstrate how to attach multiple cameras to your Raspberry Pi…and access all of…

In today’s blog post, I’ll demonstrate how to perform image stitching and panorama construction using Python and OpenCV. Given two images, we’ll “stitch” them together to create a simple panorama, as seen in the example above. To construct our image…

Over the past two weeks on the PyImageSearch blog, we have discussed how to use threading to increase our FPS processing rate on both built-in/USB webcams, along with the Raspberry Pi camera module. By utilizing threading, we learned that we…

Today is the second post in our three part series on milking every last bit of performance out of your webcam or Raspberry Pi camera. Last week we discussed how to: Increase the FPS rate of our video processing pipeline.…
