OpenCV Saliency Detection

Today’s tutorial is on saliency detection, the process of applying image processing and computer vision algorithms to automatically locate the most “salient” regions of an image. In essence, saliency is what “stands out” in a photo or scene, enabling your eye-brain connection to quickly (and essentially unconsciously) focus on the most important regions. For example — […]

A gentle guide to deep learning object detection

Today’s blog post is inspired by PyImageSearch reader Ezekiel, who emailed me last week and asked: Hey Adrian, I went through your previous blog post on deep learning object detection along with the followup tutorial for real-time deep learning object detection. Thanks for those. I’ve been using your source code in my example projects but […]

Real-time object detection on the Raspberry Pi with the Movidius NCS

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 purchasing an Intel Movidius NCS for a personal project. My project involves object detection with […]

Keras and deep learning on the Raspberry Pi

Today’s blog post is the most fun I’ve EVER had writing a PyImageSearch tutorial. It has everything we have been discussing the past few weeks, including: Deep learning Raspberry Pis 3D Christmas trees References to HBO’s Silicon Valley “Not Hotdog” detector Me dressing up as Santa Clause! In keeping with the Christmas and Holiday season, […]

HOG detectMultiScale parameters explained

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 of the HOG person detector we did not discuss in detail is the detectMultiScale  function; specifically, […]

Pedestrian Detection OpenCV

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 who has always been positive, helpful, and supportive (even when I probably didn’t deserve it). I’ve also […]
