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.
Well. I’ll just come right out and say it. Today is my 27th birthday. As a kid I was always super excited about my birthday. It was another year closer to being able to drive a car. Go to R…

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…

As we all know, OpenCV 3.0 was officially released back in June of 2015. This new update incorporated a ton of new features and optimizations, including Python 3 bindings. But the big question on everyone’s mind is: “Should I switch to OpenCV…

Last week we discussed how to use OpenCV and Python to perform pedestrian detection. To accomplish this, we leveraged the built-in HOG + Linear SVM detector that OpenCV ships with, allowing us to detect people in images. However, one aspect…

I’ve met a lot of amazing, uplifting people over the years. My PhD advisor who helped get me through graduate school. My father who was always there for me as a kid — and still is now. And my girlfriend…

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…

A few weeks ago Raspbian Jessie was released, bringing in a ton of new, great features. However, the update to Jessie also broke the previous OpenCV + Python install instructions for Raspbian Wheezy: Install OpenCV 2.4 with Python 2.7 bindings…

Today’s blog post will build on what we learned from last week: how to construct an image scraper using Python + Scrapy to scrape ~4,000 Time magazine cover images. So now that we have this dataset, what are we going…

Since this is a computer vision and OpenCV blog, you might be wondering: “Hey Adrian, why in the world are you talking about scraping images?” Great question. The reason is because image acquisition is one of the most under-talked about…
