You can master Computer Vision, Deep Learning, and OpenCV - PyImageSearch
Image ProcessingImage processing is the cornerstone in which all of Computer Vision is built. Follow my image processing guides to learn the fundamentals of Computer Vision using the OpenCV library.
Did you know that the human eye perceives color and luminance differently than the sensor on your smartphone or digital camera? You see, when twice the number of photons hit the sensor of a digital camera, it receives twice the…

Between myself and my father, Jemma, the super-sweet, hyper-active, extra-loving family beagle may be the most photographed dog of all time. Since we got her as a 8-week old puppy, to now, just under three years later, we have accumulated…

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…

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…

Being raised on the east coast of the United States I guess I should be used to the snow by now — but I’m not. As a kid, I loved the snow. I loved sledding, snowboarding, and snowball fights. But…

Awhile back I was going through /r/computervision when I stumbled across a question asking how to remove contours from an image using OpenCV. Intrigued, I posted a reply. The basic algorithm for removing contours from an image goes something like…

You know what’s a really good feeling? Contributing to the open source community. PyPI, the Python Package Index repository is a wonderful thing. It makes downloading, installing, and managing Python libraries and packages a breeze. And with all that said,…

This past weekend I’ve been really sick with the flu. I haven’t done much besides lay on my couch, sip chicken noodle soup from a coffee mug, and marathon gaming sessions of Call of Duty. It’s honestly been years since…

Last updated on July 8, 2021. A couple of days ago, Cameron, a PyImageSearch reader emailed in and asked about methods to find the distance from a camera to an object/marker in an image. He had spent some time researching,…
