You can master Computer Vision, Deep Learning, and OpenCV - PyImageSearch
Easily one of my all-time favorite papers in computer vision literature is Seam Carving for Content-Aware Image Resizing by Avidan and Shamir from Mitsubishi Electric Research Labs (MERL). Originally published in the SIGGRAPH 2007 proceedings, I read this paper for…

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…

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),…

We have now reached the final installment in our three part series on measuring the size of objects in an image and computing the distance between objects. Two weeks ago, we started this round of tutorials by learning how to…

Last updated on July 8, 2021. Measuring the size of an object (or objects) in an image has been a heavily requested tutorial on the PyImageSearch blog for some time now — and it feels great to get this post…

Today’s blog post wouldn’t be possible without PyImageSearch Gurus member, Hans Boone. Hans is working on a computer vision project to automatically detect Machine-readable Zones (MRZs) in passport images — much like the region detected in the image above. The…

The watershed algorithm is a classic algorithm used for segmentation and is especially useful when extracting touching or overlapping objects in images, such as the coins in the figure above. Using traditional image processing methods such as thresholding and contour…

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…

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…
