I’ve got a big announcement today: I will be doing more Deep Learning and Convolutional Neural Network tutorials on the PyImageSearch blog over the coming months. I’m dead serious about this — and I’ve put my money where my mouth…

I said it in last week’s blog post and I’ll say it again here today — I am not, by any stretch of the imagination, a GUI developer. I think my aversion to GUI development started back in early-High school…

I’ll be honest with you. I’m not much of a GUI developer. Never was one, never will be. I enjoy creating the occasional user interface with HTML + CSS, or hacking up a WordPress plugin to make it more aesthetically…

Here’s a common question I get asked on the PyImageSearch blog: How do I make a Python + OpenCV script start as soon as my system boots up? There are many ways to accomplish. By my favorite is to use…

Last week we learned a bit about Python virtual environments and how to access the RPi.GPIO and GPIO Zero libraries along with OpenCV. Today we are going to build on that knowledge and create an “alarm” that triggers both an…

I can’t believe this is the first time I am writing a blog post on GPIO and the Raspberry Pi. It’s a pretty big mistake on my part. I should have written this post much earlier. You see, on average,…

A few weeks ago, I wrote a blog post on creating transparent overlays with OpenCV. This post was meant to be a gentle introduction to a neat little trick you can use to improve the aesthetics of your processed image(s),…

Can you believe it’s been over four years since the original Raspberry Pi model B was released? Back then the Pi Model B shipped with only 256MB of RAM and a 700MHz single core processor. Just over one year ago…

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…
