Object Detection

Today’s post is inspired by Danielle, a PyImageSearch reader who emailed me last week and asked: Hi Adrian, I’m enjoying your blog and I especially liked last week’s post about image classification with the Intel Movidius NCS. I’m still considering…

A few weeks ago I demonstrated how to perform real-time object detection using deep learning and OpenCV on a standard laptop/desktop. After the post was published I received a number of emails from PyImageSearch readers who were curious if the…

Today’s blog post was inspired by PyImageSearch reader, Emmanuel. Emmanuel emailed me after last week’s tutorial on object detection with deep learning + OpenCV and asked: Hi Adrian, I really enjoyed last week’s blog post on object detection with deep…

Last updated on July 7, 2021. A couple weeks ago we learned how to classify images using deep learning and OpenCV 3.3’s deep neural network (dnn ) module. While this original blog post demonstrated how we can categorize an image…

Did you know that OpenCV can detect cat faces in images…right out-of-the-box with no extras? I didn’t either. But after Kendrick Tan broke the story, I had to check it out for myself…and do a little investigative work to see…

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…

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…
