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 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…

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…

Today’s blog post comes straight out of the PyImageSearch Gurus course. Inside PyImageSearch Gurus we have a community page (much like a combination of forums + Q&A + StackOverflow) where we discuss a variety of computer vision topics, ask questions,…

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…
