You can master Computer Vision, Deep Learning, and OpenCV - PyImageSearch
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…

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…

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…

This past Saturday, I was caught in the grips of childhood nostalgia, so I busted out my PlayStation 1 and my original copy of Final Fantasy VII. As a kid in late middle school/early high school, I logged 70+ hours…

OpenCV can be a big, hard to navigate library, especially if you are just getting started learning computer vision and image processing. The release of OpenCV 3 has only further complicated matters, moving a few important functions around and even…

It was unavoidable — the OpenCV 3 release was bound to break backwards compatibility with some OpenCV 2.4.X functions: cv2.findContours and cv2.normalize come to mind right off the top of my head. So how do you ensure that your code…

Last week we kicked-off the OpenCV 3.0 install fest by detailing how to install OpenCV 3.0 and Python 2.7+ on the OSX platform. Today we are going to continue the OpenCV 3.0 install instruction series by moving over to the…
