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.
Last updated on July 8, 2021. That son of a bitch. I knew he took my last beer. These are words a man should never, ever have to say. But I muttered them to myself in an exasperated sigh of…

So you’ve just built your first awesome computer vision app. Maybe it can detect faces in images. Or maybe your app can recognize prescription pills in photos. Or maybe your computer vision app can identify the covers of top selling…

I’m going to start this post by clueing you in on a piece of personal history that very few people know about me: as a kid in early high school, I used to spend nearly every single Saturday at the…

I really, really hope that someone finds this resource useful. The amount of time I have wasted over the past few months (passively) trying to get boost and boost-python to install on my OSX machine via Homebrew has been nothing…

Alright, so at this point you have been exposed to contours pretty heavily on the PyImageSearch blog. We used contours to build a kick-ass mobile document scanner. Contours enabled us detect barcodes in images. And we even leveraged the power…

Still using the original, plain ole’ implementation of SIFT by David Lowe? Well, according to Arandjelovic and Zisserman in their 2012 paper, Three things everyone should know to improve object retrieval, you’re selling yourself (and your accuracy) short by using…

Today I’ve got a little trick for you, straight out of the PyImageSearch vault. This trick is really awesome — and in many cases, it completely alleviates the need to tune the parameters to your Canny edge detectors. But before…

Over the past year the PyImageSearch blog has had a lot of popular blog posts. Using k-means clustering to find the dominant colors in an image was (and still is) hugely popular. One of my personal favorites, building a kick-ass…

So in last week’s blog post we discovered how to construct an image pyramid. And in today’s article, we are going to extend that example and introduce the concept of a sliding window. Sliding windows play an integral role in…
