Many strategies used in machine learning are explicitly designed to reduce the test error, possibly at the expense of increased training error. These strategies are collectively known as regularization. —Goodfellow, Bengio, and Courville (2016) In previous lessons, we discussed two…

Last week, we discussed Multi-class SVM loss; specifically, the hinge loss and squared hinge loss functions. A loss function, in the context of Machine Learning and Deep Learning, allows us to quantify how “good” or “bad” a given classification function…

Now that we’ve had a taste of Deep Learning and Convolutional Neural Networks in last week’s blog post on LeNet, we’re going to take a step back and start to study machine learning in the context of image classification in…

Did you know that OpenCV can detect cat faces in images…right out-of-the-box with no extras? I didn’t either. I had to check it out for myself…and do a little investigative work to see how this cat detector seemed to sneak…

I said it in last week’s blog post and I’ll say it again here today — I am not, by any stretch of the imagination, a GUI developer. I think my aversion to GUI development started back in early-High school…

Last week we learned a bit about Python virtual environments and how to access the RPi.GPIO and GPIO Zero libraries along with OpenCV. Today we are going to build on that knowledge and create an “alarm” that triggers both an…

We have now reached the final installment in our three part series on measuring the size of objects in an image and computing the distance between objects. Two weeks ago, we started this round of tutorials by learning how to…

Last updated on July 8, 2021. Measuring the size of an object (or objects) in an image has been a heavily requested tutorial on the PyImageSearch blog for some time now — and it feels great to get this post…

Last week’s blog post taught us how to write videos to file using OpenCV and Python. This is a great skill to have, but it also raises the question: How do I write video clips containing interesting events to file…
